Maximum speed internal hard drive configuration

Barefeets posted an interesting speed test using 2 velociraptors as the boot drive. I am considering the same setup. I also want to use three other internal drives (a total of 5 drives) set up as a PS swap raid and Image files raid. The fifth drive would be in the lower superdrive bay.
I'm using Seagate 1.5T 7200.11 drives and creating three partitions on each drive. The first partition on each drive will be 15GB for a total of 45GB for PS Swap. The second partition on each drive will be 100GB for a total of 300GB for writing and reading PS files. The remaining partitions on each drive (about 1.14T) will be left alone and will act as stand alone drives. I will move data from the 300GB raid to one of the remaining large partitions and chronosync to the other two drives for redundancy. Routinely that data will move off the computer to outboard backup drives. If I have a drive failure I have the two remaining drives, plus outboard, to rely on. Does all of this make sense? Am I missing anything?

Some results on CS4, Geekbench and CineBench:

*A Case For More Memory on your Nehalem Mac Pro*
Adobe After Effects CS4 (and CS3) spawns subprocesses -- one for each core -- when 'multiprocessing' is enabled in Preferences. Each of those subprocesses can grab up to 3GB of RAM. We typically use the Total Benchmark created by Brian Maffitt to benchmark with After Effects. If you run Activity Monitor during the rendering, you can not only observe the multiple subprocesses but you can observe how much real memory each of them is appropriating as the second phase of the project render progresses toward completion. When we had 16G installed, we observed 13GB of real memory in use.
*PHOTOSHOP CS4*
Only certain functions/filters in Photoshop use multiple cores. Some "MP aware" functions include Rotate, Gaussian Blur, Motion Blur, Radial Blur, Lighting Effects, Lens Flare, Pointilize, Sharpen Edges. These "MP aware" effects use all available cores.
As for memory usage, Photoshop is able to grab more than the 3GB memory cache defined in preferences. If you overflow that and there is memory to spare, OS X Leopard will allocate unused memory as a virtual scratch volume. If you are editing RAW photos with lots of layers and lots of history states, having the 8 memory slots on the 8-core is a big advantage.
http://www.barefeats.com/nehal04.html
You want 16-32GB of RAM. Turn off Spotlight on scratch volume and never ever use the boot drive for primary scratch pref or for media files, once you get into large files that is paramount. Even the stripped boot will help a lot.
4GB files can really push a sytem to the limit, and require optimizing everything.
Adobe believed it was safe to use Carbon code rather than learn new coding, new and different compilers. And a lot of programs are not dealing with more than 2 cores all that well, and even Intel keeps updating their compilers they offer to help improve code. - So yes, and now is perfect time with the move to Snow Leopard for CS5 to go 64-bit, but just as important, multi-core aware. They already know how, on Windows 64, to use a GPU for rendering images in CS4 (look up the Quadro CX) for "GPGPU."
With RAM and properly configured storage, and multiple discreet arrays, each on their own drives probably, I've seen G5 owners with 3-5 10K VelociRaptors load large apps and files in sub-zero bounce - and breath new life into G5.

Installed Samsung F3 1TB internal Hard drive configuration partition

Hi,
Have just installed a Samsung 1tb internal hard drive and now it comes to formatting and partitioning it not sure what amount of gb and how many partitions to do. I have all my itunes music and films stored on an external 1tb hard drive for information, and also have an external 320 gb drive for back ups. So any ideas what to do with the partitions and gb on the internal drive.

There will be a lot of views on how the drive should be partitioned, so I will offer my opinion, and state it is only one opinion.
Take a look at the amount of space you have been using for your operating system, are you planning on upgrading the OS, and then set a partition for only the OS. Make it large enough to allow for future upgrades, maybe 30-40 GB larger than needed so there is enough space for doing installs.
Keep a partition large enough for all of your software, maybe have that be most of the remainder of the drive after the OS partition.
Since you keep music, etc., on an external drive it should be easy to keep the internal drive in good shape and unfragmented.
You could set a partition for temporary files, the /tmp file system, but it is easy to fill that up with a lot of web surfing and get yourself in trouble on space.
Anyway, my view is a good size partition to allow for OS and future OS installs, and the rest for software.

Which speed internal hard drive should I get for FCP editing on a Mac Book

I am going to buy a new Mac Book Pro notebook to edit a feature documentary with FCP. My footage is all on 7200 rpm G-raid external drives. Question: should I buy the 4200 rpm, 5200 rpm, or 7200 rpm hard drive for the notebook? I really like having more hard drive space - but I want to be able to edit quickly, play back thru my deck to a television, etc as well. Editing is miniDV with typically 4 tracks video + audio. Appreciate hearing from anyone who has direct experienc and has compared.

Instead of focusing on the internal drive, I would
advise getting an ExpressCard/34 firewire card to
create a second FW bus for capturing footage to the
G-Raid externals.
Hmm, is that better than just using the FW400 port for the camera and the FW800 port for the external harddrive?

MacBook Pro (13-inch, Mid 2009) - Maximum internal hard drive size and speed?

What is the maximum size of hard drive and speed for an internal hard drive to my Macbook Pro (13 inch, Mid 2009), please?
I bought myself a Technics 1TB, 7200 rpm internal hardrive. Made a clone successfully in Super Duper.
It fits, but It is not available for starting up my Macbook Pro. Not available in System Prefs, but visible and grey in Disc Utility.
Although it starts up my Mac Pro just fine.. but not my Macbook Pro.
Is there a limit of hard drive specifics?
What is the maximum size of hard drive and speed for an internal hard drive to my Macbook Pro (13 inch, Mid 2009), please?

Thanks for the reply
I cloned the Technics HDD ( 2,5" HGST Travelstar 7K1000 - 1 TB : HTS721010A9E630) from the MBP.
I tried to boot it up with my Technincs ( 2,5" HGST Travelstar 7K1000 - 1 TB : HTS721010A9E630) installed in my MBP (as my internal hard drive).

Maximum size for the internal hard drive

I have an Intel based 24" Imac. As soon as my Apple care runs out I want to replace the internal hard drive with something larger. Does anyone have information on the maximum size I can install?? I currently have 320gb, but am looking to increase to 1tb but I don't know if my Mac can handle it.

1TB will definitely work as this was even a build to order option when it was for sale. I'm pretty sure as long as you're not using FAT32 whatever size you put in should be compatible.

Hard Drive configuration for speed

I've got a question regarding the best hard drive configuration for my mac pro. I'm looking to increase the boot speed, application load speed and particularly the speed with which hard drive intensive photoshop processes complete. Right now I'm just using some normal SATA II drives. I'd appreciate it if you could give me some feedback on the various options I am currently considering.
-2x 64GB SSD in a RAID 0 for OS X and applications with some large SATA drives for storage
-4x 300GB VelociRaptor 10k RPM SATA HDD in a RAID 0
-2x 147GB SAS 15k RPM HDD in RAID 0 with some large SATA drives for storage
I am particularly in the dark about the controllers I'd use for each solution. Clearly, I would absolutely require a PCIe card for the SAS drives, but would there be a marked advantage to using a hardware RAID card for the SATA drives over the software RAID in OS X? Also, how easy is it to get the mac pro to boot off drives connected to a controller card rather than the standard setup? And lastly, if there is good reason to use a card, are there any in particular that you would recommend?
Thanks a lot!

2. No. Do not make two partitions unless you do not plan to use Boot Camp Assistant to install Windows on that partition. If you plan to create a Boot Camp partition then you must partition the drive as one Mac OS X volume. Boot Camp Assistant will then create the Windows volume.
3. This drive must be repartitioned and reformatted as follows:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu to two. Use the graphic resizer to set the desired sizes for each volume as you want. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the first volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Select the second volume you created and repeat Steps 4-6.
4. Now here I don't know what you think is your best option. You can buy any two hard drives you want. The ones I identified were only an example of what you could purchase for under $300. There are others, slightly more expensive, that would work, and you would still be under your $300 budget. The Samsung drives are good drives and reasonably priced, but they are just one of several alternatives. You should do some checking on your own before making your decision. I'm just giving some guidance, not trying to tell you what you should do. I've provided three sites where you can read reviews and benchmarks before you decide. You need to "own" your decision.
As for how you configure these two drives that's a secondary issue. I would recommend using them for backup. Two possible arrangements are a Mirrored or a Striped RAID array. A mirrored RAID array would create one volume that has a 1 TB capacity. Everything saved to that volume is essentially saved twice - once on one drive then a copy is mirrored to the other drive. This is not what you described in your Item 4. That's not how it works. Anything saved to the mirrored RAID array is saved the way I described it just above. It makes no difference where the files come from.
Now you can use the mirrored RAID array as a Time Machine backup drive if you want, but then you should not use it for other data storage. You would need the entire capacity as backup for both of the 500 GB drives you currently have. A mirrored RAID provides some data redundancy by having a copy of everything one each drive. Thus, if one drive fails the other drive still functions and your data backup is intact. Mirrored RAIDs are generally no faster than an individual drive that makes up the array.
The second suggestion was to make a Striped RAID array. This type of array produces one volume that is twice the size of the the two drives that make up the array. Thus, you would have a single volume that is 2 TBs in size. You can use this volume for your Time Machine backups also. Striped RAIDs do not provide any data redundancy. If one drive fails all the data stored on the RAID will be lost. However, Striped RAIDs are nearly twice as fast as either drive that makes up the array. This would give you very fast storage and backup.
You could also just leave the two drives to operate independently. Use on for Time Machine backups, use the other for more storage space.
Other possibilities abound. It's pretty much up to you to decide what will fit best into your needs today and in the future. Don't feel obliged to do what one person tells you. Five different users on the Discussions will give five different opinions.
I suggest you educate yourself a bit on backup and restore by reading the FAQ about backup and restore at The XLab FAQs.
Following is more information on RAIDs:

For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?
OS X has software for creating RAIDs by using Disk Utility. Open Disk Utility and select DU Help from the Help menu. Search for "raid" without quotes. You will find information on how to set up mirrored and striped RAIDs using Disk Utility.

Router configuration and Internal Hard Drive

Hi, I was wondering if i installed a new internal hard drive into my computer would i have to reconfigure or reinstall my router? Also a little off topic but should i get a internal hard drive or an internal?

oh ok so all my router settings would stay the same then right. I thought it would change the settings because the old internal hard drive has everything saved onto it such as my network settings and router configurations. Sorry for questions im still a newbie at this stuff.

TiBook 1Ghz -- Maximum internal hard drive limit?

Looking for a definitive answer to the question of hard drive capacity limitations in the TiBook --
I have the last of the mighty TiBooks -- a 1Ghz, 15". I want to replace the internal hard drive. Is there a limit to the drive capacity I can use and access in this PowerBook? Is it the 120 GB limit that affects most older Macs, or can I put a 160 GB (looking at WD Scorpio...Circuit City $79!) and be able to access the whole thing?
If anyone has the answer, has experience doing this or can point me to the KB documents, I'd appreciate it. Thanks.

The Drive Compatibility Database at xlr8yourmac.com contains four reports of successful installation of 160GB drives in 1GHz Titanium Powerbooks. There are no reports of unsuccessful installations in that model. There are no reports at all of 160GB drive installations in the 867MHz Tibook, successful or otherwise. There are also no reports of 160GB drive installations in earlier Tibook models (800MHz and slower), successful or otherwise. Previous posts in the Tibook forums have reported the earlier models' inability to "see" more than 127GB of a 160GB drive, no matter how it has been formatted or prepared.
Thus, Hardy Geer's report (above) about the 1GHz Tibook is quadruply confirmed, and whether or not the simultaneously-produced 867MHz Tibook can use 160GB drives remains uncertain.
To find the four reports, I searched the database for Powerbook G4s running OS X 10.3 and 10.4 in which hard drives manufactured by Hitachi, Fujitsu, Seagate, Western Digital and Samsung, all of whom make 160GB drives, had been installed. Then I scanned all the reports that came up, to determine which PB G4 model each report concerned.
There were many more reports of successful 160GB drive installations in Aluminum PB G4s, including at least one in the original 1GHz 17" Albook introduced in January 2003 - the same time as the 867MHz 12" Albook. Though Albooks aren't my specialty, I suspect this indicates that all Albooks can use 160GB drives, and perhaps larger ones. There was only one report of the installation of Western Digital's recently-introduced 250GB IDE drive (the only one bigger than 160GB currently on the market) in a Powerbook, and that was in a late-model 1.67GHz Albook.

Speed of Working Between Two Internal Hard Drives

I have two identical internal hard drives, the hard drive in slot-A is the boot drive and contains all my applications, the drive in slot-B contains all my work files (Photoshop and Illustrator files, Word and Excel, digitized video, etc).
My question is, how much lag time is there with me working in an application on drive-A with the files from drive-B; if any? Is it better to have the work files on the same drive, such as if I moved them all over to drive-A?
Thanks.

Going off the advice of the much more experienced guys like Hatter on this forum, the way you have it set up currently is much faster. They even have instructions for moving the user files onto the B drive. I haven't tried that yet, but my iTunes and iPhoto data files are there, and it really seems to help. Many posts on details for doing that in this forum, but I'll defer so as not to take a chance of forgetting some important step.

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson
Power Mac G4 Quicksilver 867 Mac OS 9.2.x 17" Studio Display, 512MB RAM

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson

Slow Mavericks - internal hard drive failure?

Hi
I recently updated my iMac 2.5 GHz Intel Core i5 4GB RAM to Mavericks. Before I was working on OS X Lion 10.7.5. Until the day I updated I never had any problems with my computer being slow, unless when I was using heavier applications or heavy files like in Adobe PS for example.
Since I've updated however, it often happens that the icons in my launchpad load slowly, my computer shows the spinning circle more often, and especially Microsoft applications (Word and Excel) take much longer before they are launched. I don't think I have to explain how this is bugging me, since we all like a fast computer. So I kind of regret updating.
I wanted to downgrade to 10.7.5 again, but this doesn't seem that easy even though I know my way around reformatting Apple computers…
So this is kind of a last option. Now I went to the Apple store in Belgium, and they told me that it could be a bug and that I should wait for the next version (yeah right…) or that it could be my internal hard drive was failing. Now I tried to find some information on how to recognize a failing hard drive, but I mostly bumped in to extreme errors. So I was wondering how to know your internal drive is failing? Second of all could it be failing all of a sudden? Since I hadn't had those problems before I updated. Thirdly is it possible that the next update would solve these problems, as they mentioned? Could a clean install help?
Anyway, I find it pretty weird, and there's a lot of different opinions and options, so I would like a more expert view on the problem, so get to a solution and an answer whether or not my disk could be failing, cause then I would like to get it replaced.
Thanks in advance for your advice!

In a previous topic, I was asked to deliver some information in order to get a diagnosis, but there has been no more answer. This is why Now I would like to ask if anyone can interpret this info below… Cause I have no idea what it means…
When I entered the following query in Terminal this is what happened:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}' | open -ef
It produced a text editor window without any content. It didn't take long either, just one or two seconds. (Is this normal?) Does this mean my hard drive is intact?
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any. - there are none
Reset the System Management Controller. - does this simply imply that I have to hold the power button for 10 seconds?
Run Software Update. If there's a firmware update, install it. - done
If you're booting from an aftermarket SSD, see whether there's a firmware update for it. - not the case
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
- not the case
If you have many image or video files on the Desktop with preview icons, move them to another folder.
- not the case
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change. - not an icloud user
Check your keychains in Keychain Access for excessively duplicated items.
- not the case either
Boot into Recovery mode, launch Disk Utility, and run Repair Disk. - is this necesary if the former step didn't bring up any text in the text editor window?
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
- not the case
Since I am doing jack right now and am solely typing this topic, the highest %CPU is about 2-3 percent and is "Safari web material". In the second place there is Safari with about 1-1.5%.
System is about 0.76, user 0.89 and inactive is the leftover. 98,"something".
In the memory tab:
In the disk tab… It varies a lot:

Internal hard drive does not mount in disk utility

My internal hard drive no longer mounts in Disk Utility. It is grayed out. I have extraordinarily frequent spinning beach ball/freezes, in Safari or Apple Mail. The most recent symptom: upon rebooting or just starting up, I see flashing black on the display. This has been occuring for more than six months. Of course, I have made total and frequent backup's. I bought new RAM, but have not yet installed it, and I susect this might help. I have done repeted troubleshooting many times each: Apple's Disk Doctor, Repaired Permissions, Reinstalled the Mac OS, safe boot, Alsoft's Disk Warrior, Apple's longer Harware Test, etc. I have worked as a new user, too. All tests done report that all is well. What od you thnk the problem is? Must I drive 1.5 hrs. each way to the Genius Bar at my nearest Apple Store? Might I try to erase the hard drive as a fix? I hate to do this, only as a last resort, as it is so time-consuming. Should I just update my Mac OS? Please advise, out there, if anyone can offer any advice, I would be greatly appreciative.

The list of issues you posted probably would not get shorter if you attempt to 'upgrade them' away, as usually that kind of effort is not effective yet may expose more of the same problems while not necessarily revealing the original weakness. Another OS X installed over a set of problems seldom helps.
How full is the hard disk drive? If it is too full, or has been very busy in use several years, it may be time to replace the HDD and perhaps put a larger capacity one in the computer. And if the main computer hardware checks out OK (tested under a variety of duration and stress tests) then also consider a RAM upgrade if the device is not already at the maximum capacity.
When was the last time the hard disk drive was devoid of content, maybe wiped -- erased and reformatted by a third party disk utility or have a utility overwrite the entire HDD with zeros? This used to be a common tech service in the course of a major effort to restore a Mac. Or Defragment?
If you can do the latter, this could help resolve bad sectors and remove old data or corruption on the hard drive. Or get a new HDD and before committing a new OS X install & apps to it (or a re-clone of a complete backup) test the drive and be sure it is ready for use. Not all new drives are perfectly ready; some need to get exercise first.
I'd bet on a new hard disk drive of larger capacity (also note spin RPM rate and data speeds) and a full RAM upgrade.
If you have a backup clone on an external hard disk drive (in a boot-capable enclosure) you could really go to town and before you erase the main/only hard drive, make a backup clone and test its ability to boot the Mac. Or put the old drive and content in a suitable boot capable enclosure of the kind with its own power supply, and deal with it later.
Then consider a later version OS X -- whatever most recent version that model can support... {edited}
Good luck & happy computing!

Best Hard Drive Configuration on New iMac?

Hi all,
I am in the process of purchasing a new iMac and will be installing Lightroom on it. This will be my first installing Lightroom on one of my machines, so I am not very familiar with the program, though I have read up on it (and will continue to do so) and have seen it in action before.
I plan to get a 27' iMac, 3.4 i7 CPU, with at least 8GB of RAM (will probably upgrade to more later). I have the option of selecting a 1TB Fusion drive, which is sort of a hybrid drive (a small part of which is SSD for most often used files/programs and the rest is a regular old hard drive), or a 3TB Fusion drive. I'm trying to decide which would be better for Lightroom.
Obviously, the 3TB brings the convenience of size and the ability to store more pictures on a single HD without the need of an external drive (at least right now). However, I am leaning toward the 1TB because the 3TB does not allow one to install Bootcamp, which is a program that let's the user run Windows on the iMac, which I may want to do at some point for work purposes.
All things being equal, and except for purely backup purposes, do most users split up their storage when using Lightroom or they just use one large internal hard drive? Would this have any impact on performance? To be honest, the whole catalog thing is throwing me for a loop. Sounds like I could store the physical images on an external drive, and just have Lightroom itself and the catalog file on the internal Fusion drive, but I'm wondering if this would at all degrade performance/speed of loading/viewing/editing pictures. Obviously, I'm assuming much will depend on the speed of that external drive.
I will continue to read up, but I would appreciate any tips regarding the HD situation before I place my order, as well as any general pointers for a first time Lightroom user starting fresh so that I can get off on the right foot.
Many thanks!

Hallo,
I have the same or at least very similar question.
Just ordered the 21.5" imac with 1TB fusion drive. I need to transfer 450GB of photos from my old windows PC to the new imac set-up. This set-up will include some drive(s) for back-up, but not sure yet which drives.
Just moving the 450GB of photos to imac HD seems a bit much: with photos, applications and some other stuff 60-70 % of the imac HD would allready be consumed up right from the start.
I am using Lightroom for organizing, editing, etc. of my pictures. So this should run as smooth as possible.
Any advice on a good configuration on how to work with iMac, Lightroom, 500 GB of pictures, external HD, back-up is welcome.
thanks,
Maarten

Installing internal hard drive on an old iMac

I am an absolute novice when it comes to taking apart a computer and know nothing about any technical terms or parts. I was able to install a new battery when the original died, so when the "genius" at the Apple Store said I could install an additional internal hard drive, I gave it a whirl. Before I try to return the hard drive, I thought I would give this a shot.
My iMac is a 400 MHz PowerPC G3, one of the early generations, if the not the first (see-through cobalt blue exterier). I am running with 256 MB of memory and the CPU type is PowerPC 750 (83.0). I have Mac OS X Tiger, version 10.4.6 and this machine had been working great until we recently purchased our first iPod. Now with all the music being loaded in iTunes, the iMac has slowed down and even frozen when trying to use a few applications at once.
I figured I needed more hard drive space and/or memory and the people at the Apple store suggested I purchase a Seagate 80 GB Barracuda and install it myself.
Well, I got the computer apart and found the old hard drive, but that is about as far as I can go. I read about making the new hard drive the "slave" hooking up the BLUE, BLACK and GRAY connectors on the new cable, but I don't know a motherboard from a jumpdrive and the new connectors do not match up with the old one (the Blue connector is not the same size as the old one that I think was going into the motherboard). There is also something about an unused power cable in the old computer for the new hard drive, (which I did not see) and a suggestion that I get a Y-shaped power cable from an electronics store, which even if I knew what it was, I would not know where to begin connecting it. Not only does the new connector not match up, it is about 10 times as long as the old one, which leads me to the final issue: if I could get this all hooked up and power-supplied, where in the world would I put the new, additional hard drive? There is no room I can see adjacent to the current hard drive. Do I have to take the thing further apart?
I realize this may provide a great laugh for anyone who knows how all this works. If trying to walk someone through this process using Apple Discussions does not make sense, I completely understand. I had nothing to lose (except possibly the cost of the Seagate drive if they won't take it back).
I was able to put everything back together after taking the old hard drive out, so I think I could do this if the parts were all there and matched up....but I would still need to know where to put the new drive!
Any suggestions are appreciated. I have already resigned myself to the fact I may just need a more expensive external drive...I just have few available ports.
Thanks,
Conrad Farner

"...when the "genius" at the Apple Store said I could install an additional internal hard drive, I gave it a whirl... if I could get this all hooked up and power-supplied, where in the world would I put the new, additional hard drive?"
Your iMac has room for one hard drive and the optical drive (CD-ROM, DVD-ROM, CD-RW, etc.). Any ribbon cable supplied with the hard drive or a Y-splitter power cable is of no use in the iMac. The new drive must replace the original, because the two can't coexist internally. Additionally, you need to configure the new Seagate as "master," since the optical drive is "slave." Refer to Seagate's accompanying documentation, for instructions on setting the small jumper(s) to designate the drive as "master." The drive may have been factory-configured for "cable select," which isn't supported in your iMac. After you get that straightened out, you'll need to boot the computer from the Tiger installer CD and use "Disk Utility" to format the new drive as a Mac OS Extended (HFS+) volume. You may also want to partition it as well.
Incidentally, you should post any future questions about your iMac in the Forum dedicated to the CRT-style iMacs. You'll receive informative answers to any questions that you might have, from those who are thoroughly familiar with your model iMac.

PLEASE HELP me select new internal hard drive for Macbook Pro 2012 (non-retina)

Good afternoon.
I just bought a Macbook Pro 2012 (non-retina) 15 inch from a friend. I think it is running Mountain Lion (has not been upgraded to Mavericks yet), and has iLife on it. It came with the stock 500 gb 5400 rpm internal hard drive. At home, I only have the Snow Leopard OS installation Cds and a copy of iLife 2011 installation Cds. I am going to buy 16 gb of RAM from Other World Computing to install.
I want to replace the hard drive with a 1 tb hard drive, preferably something that is $100 or less.
I talked to Other World Computing (OWC) and looked at the Data Doubler Option to replace the optical drive with a Solid State drive, but decided that for now I want to keep the optical drive inside the computer for portability issues.
I know that Solid State drives are better, but they are still too small, and I want the ease and portability of a 1 tb size INSIDE my computer.
Initially I was going to order this from Other World Computing: 1.0TB 2.5" HGST Travelstar 7K1000 7200RPM SATA 6Gb/s 9.5mm Notebook Drive 32MB Cache. *'New' Factory Replacement with 2+ Year HGST Warranty*    As of April 4, 2014 it's on sale for $79
But then I started reading some of the discussions online and thought maybe I should get a hybrid solid state drive?
I saw on Amazon the Seagate 1TB Solid State Hybrid Drive SATA 6Gbps 64MB Cache 2.5-Inch ST1000LM014 It's on sale for $94.
But according to some reviews, this Seagate has a platter that is only 5400rpm, unlike the previous Seagate Momentum that has a platter speed of 7200rpm.
How reliable are the Seagate, versus a Toshiba or Western Digital or Hitachi or something else?
Here are my questions about replacing the hard drive:
1. Is a hybrid solid state drive going to need some kind of special formatting after I put it into the macbook so that I can put the operating system on it?
2. Is a "normal" platter hard drive more reliable than a hybrid solid state drive?
3. Is there any additional driver or special software that I have to install for a hybrid solid state drive?
4. Currently there is no personal data stored on the computer. Can I just put the new hard drive in, and then insert the snow leopard install cd?
5. If I install snow leopard, can I just go to the App store and get the free upgrade to Mavericks?
6. If I want to do the "Data Doubler" option in the future and add a normal Solid State drive into my computer, will it have trouble interacting with the 1 tb hybrid solid state drive?
I would love to get some recommendations about the smartest option to upgrade my hard drive with something that will be fast (I edit lots of photos) and large (1 tb) that isn't going to cost too much. I don't know much about the different brands or options (and there are so many listed in tons of online reviews), that I got really overwhelmed and confused by the info out there.
I would really appreciate any help and advice. I've never switched out a hard drive before.
PLEASE HELP !!! Thanks!

1. Is a hybrid solid state drive going to need some kind of special formatting after I put it into the macbook so that I can put the operating system on it?
The boot drive, regardless of what it is, needs to be formatted as Mac OS Extended (Journaled). This is standard with OS X.
2. Is a "normal" platter hard drive more reliable than a hybrid solid state drive?
There are arguments pro and con. Bottom line, SSD's and hybrid drives are still quite expensive per GB than standard hard drives. If you have the bucks and are a speed demon, go ahead.   I have better use for my money.   Standard hard drives are mechanical and may wear out over time. But even though SSDs are not mechancial, they can still go bad and ultimately they even have a limit to their write capacity. The jury is still out on this debate.
3. Is there any additional driver or special software that I have to install for a hybrid solid state drive?
No
4. Currently there is no personal data stored on the computer. Can I just put the new hard drive in, and then insert the snow leopard install cd?
You can physically put the hard drive in but probably not install Snow Leopard on this MBP.
The mid-2012 MacBookPro9,1 models came with Lion 10.7.3 (11D2097) preinstalled.   It is very unlikely you would be able to install Snow Leopard on it. Historically you cannot install a version of OS X that is earlier than the version that came with your Mac (even if you replace the hard drive).
5. If I install snow leopard, can I just go to the App store and get the free upgrade to Mavericks?
Not via Snow Leopard on this MBP. See my response to #4.
6. If I want to do the "Data Doubler" option in the future and add a normal Solid State drive into my computer, will it have trouble interacting with the 1 tb hybrid solid state drive?
No. They are completely independent of each other; they are just independent storage units (drives) and their RAM does not interact.
