PPC G5 HDD question

I have a G5 PPC with a 500 GB Western digital HDD installed. The problem is that system info is only reporting 465.17 GB total on the drive. Is there a fix for it?

That's not a problem - it's just due to the differences in the definition of a gigabyte.
HD manufacturers define a GB as 1,000,000,000 bytes, which is 1,000 x 1,000 x 1,000. Operating systems use the binary definition of 1,024 x 1,024 x 1,024 which is 1,073,741,824.
If you assume a 500GB drive is exactly 500,000,000,000 bytes and divide by the binary definition, you'll get 465.66. Subtract a little for what's lost due to formatting, and you're right at what you're experiencing.

HDD questions...

I recently acquired a 17" iMac G5 for free and am trying to repair it. I thought that the original HDD was bad until i recently booted to my 10.4 install disk and opened the disk utility to find the disk there...
I had another hard drive hooked up via an external USB enclosure, but it wasn't showing in Disk Utility. Not only that, but the only time that the internal HDD would show up is if that external drive was connected. I tried to erase the disk and start fresh, but the Disk Utility comes up with some weird error, and does not continue...
My questions:
What could be causing this, and would reformatting the HDD with all zeros correct this problem?
I will try to use firewire target disk mode with another PPC mac (The one listed below) to see what can turn up. I'll keep what I find posted.
thanks,
Superd@ve

Take a look at Console and see if the are any heat related messages in your system log. You likely have a failing power supply or some bad caps.

Aperture - library management and external HDD question

Hi all.
I have just graduated from a point and shoot to a Panasonic GH2 (love it), and have now begun using Aperture 3 rather than iPhoto on my early 2008 MB Pro to manage my photos going forwards. Of course, I’ve now discovered that Aperture is quite the resource hog and so it’s upgrade time (darn, “have” to buy a new ‘puter!). I have a 2011 MB Pro (2.3Ghz i7 with 512GB SSD) on order and 8GB of DDR 3 arriving from Crucial. Since I have this brand-new-computer opportunity I want to make sure I’m organising things properly before I start transferring things across, and so have a few Aperture-related questions. (In case it’s relevant, I’m shooting in RAW+JPEG. So far I’ve been using RAW as master, but have since learnt it might be a good idea to import JPG as master and switch to RAW only when I need to make corrections, so I’ll probably do that going forwards.)
I understand that moving to referenced masters on an external drive might be a good idea and save me precious SSD-space. To that end, questions are:
1. Can anyone recommend a companion external HDD for Aperture and the 2011 MBPro? I guess either FW800 or Thunderbolt are the way to go. The Lacie Little Big Disk Thunderbolt might be an option but is this overkill for Aperture masters or would FW800 be sufficient. I’ve also seen the G-Tech G-RAID mini, Lacie Rugged – thoughts welcome.
Key requirements are a) as compact as possible, and b) bus powered.
2. What kind of performance can I expect if I go down this route? Is there going to be significant loading/processing delay whenever I switch to a new image?
3. How will Aperture cope with (eg) syncing photos to iPad / iPhone if the drive containing the masters isn’t connected? Put another way, are JPG renders saved in the Aperture library (i.e. on my MBP SSD) or with the masters?
Thanks in advance to anyone who responds!

OWC (an excellent vendor) has the Elite Pro Mini hard drive that meets your specs:
http://eshop.macsales.com/shop/firewire/EliteALmini/eSATA_FW800_FW400_USB
Thiunderbolt drives are not mainstream yet but eSATA and FW800 both work well. The multiple connection methods of OWC drives allow very desirable flexibility when purposing/repurposing drives.
Note too that the MBP optical drive can be replaced with up to a 1-TB hard drive DIY or OWC will do it for you. That is what I am doing with my 17" 2011 MBP.
2. Is there going to be significant loading/processing delay whenever I switch to a new image?
SSD latency is orders of magnitude less than hard drives. Switching to a new image even fast hard drives with fast connectivity add significant latency delay. To avoid that what I do is leave (Referenced) Masters on the SSD until all editing is complete (which may be a few weeks). Only then do I use Aperture to change the Referenced Masters location from the SSD to a large external drive.
What kind of performance can I expect if I go down this route?
With Masters on the SSD and 8 GB RAM imports/exports are very fast and all Aperture editing is essentially instant. You will be pleased!
Suggested workflow steps for Referenced Masters:
• Use a FW card reader or MBP slot to copy to a file folder on the SSD (never directly into Aperture or any other images management app). With fast camera cards copy times are quick, but cheap slow cards can slow this step down a lot.
• Eject and physically disconnect the card reader.
• Back up that file folder on external drive(s).
• Only after backup is complete, reformat the camera card in-camera.
• Import images into Aperture from the file folder on the SSD.

SATA HDD question

Hi ppl
Quick question.
When I built my PC I used a HDD with a normal P-ATA connection with the IDE cable.
I am building a PC for my friend and was wondering if I should get a SATA drive.
R they rly that much faster or is it just a gimick?
Also when u install one for the first time and boot up is the SATA drive automatically recognised like a normal P-ATA drive.
Sorry new to this. Thanks for your help
SAspaz

Hey again
Umm alright I dont rly mind if I get either of the drive now. Just a quick question. When I built my rig I just attached the P-ATA HDD using a normal IDE cable and then when I booted I just installed windows xp via CD etc and it just detected my IDE HDD was there.
Now if I built the new PC with a SATA drive and I connect the SATA port and the power to the drive and boot up the PC. Will it automatically recognise the HDD and I can install windows normally or wot. Is there anything I would have to do differently for SATA compared the PATA
Cheers guys. Noob wen it comes to the SATA drives.

Adding second HDD questions

I see this in the manual--
Supports the following double hard drive
configurations:
● 2 TB: (1 TB, 5400 rpm, 12.5 mm × 2)
● 1500 GB: (750 GB, 7200 rpm, 9.5 mm × 2)
● 1500 GB: (750 GB, 5400 rpm, 9.5 mm × 2)
● 1 TB: (500 GB, 5400 rpm, 9.5 mm × 2)
Does that mean that if I have a 750 gb 5400 rpm drive that it will only support another exact same drive? or can I add a 1tb drive @ 7200 rpm for second drive? Thanks!!
This question was solved.
View Solution.

Hi,
Yes, you can add a 1Tb 7200rpm HDD in the second drive bay.

Time Machine w/ external HDD question

Hello all! Just started using Time Machine with an external HDD. So, here is my question, if my HDD (USB) is not attached for a week, and Time Machine is running, will I get some sort of error message letting me know that the backup volume cannot be found? Also, when I reattach, say one week later, will Time Machine pick up and backup those items over the past week? Please advise. Thanks!

Time machine might give you an error but its very unlikely. And as for unplugging the drive, yes time machine will pick up were it left off and update the changes you have made. I usually only hook mine up every couple weeks cause I don't make very many changes.

Mac Book HDD question

I actually have 2 questions for my macbook. I have a late 2008 aluminum body 13 inch macbook 2ghz intel core 2 duo with snow leapord . 1st question the 128gb hdd is almost full i have about 29 gb left. I want to upgrade to an internal hdd can this be done? And any recommendations would be awesome with a link to the HDD.
also the same laptop is crashing. I dont know what seem to be causing it. Itll randomly just crash and it takes for ever to reboot. the battery is fully charged.
thanks

TM will backup everything you do not specifically exclude.
You might try reinstalling OS X. See the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Encrypted external HDD question

Hi,
Hope this doesn't sound like a daft question, but I am trying to learn as much as I can. I have encrypted my external drives, but I was wondering where the decrypt key is. Is it held on the computer or on the drive itself? I ask as in the future either when I upgrade, or as the result of a serious problem with my Mac I would want to restore from one of the drives so need to know if it will work ok on another machine. Also if the decrypt key is on the external HDD isn´t that a security flaw as any hacker would have the key with which to decrypt together with the files?
Thanks

Hi Linc,
I have two external drives, one runs os and has my files on it and the other is a time machine back up of it. Now that I have encrypted the os disk it asks for the drive password on boot up, so I assume that the decrypt key is on the os drive and that I can use that HDD on any Mac but just inputting the password?
Is that correct?

New HDD question

So I just bought a new HDD for my Powerbook and I am going to install it myself. I am pretty confident in my ability to physically install it, but I am unsure of the software end of things (being I am a switch over from Windows). I have the original disks that came with it. What do I do once the new hard drive is installed? If you could simplify that would be great cause I'm a complete Mac n00b. Thanks!

Welcome to Apple Discussions.
So I just bought a new HDD for my Powerbook and I am going to install it myself.
You don't say which PowerBook G4 15" you have, but you will find step by step directions for installation here. Select you PB in the list then navigate to the directions for Replacing HDD. In addition here are few tips you may find helpful:
• Print out the ifixit directions as well as the screw guide ahead of time.
• Be sure you have the right tools. You don't want to damage the screw heads or you may never get them out. And the Torx screw driver is critical.
• I use small medicine cups one for the screws in each step. I nest them so that the last ones out and the first to go back in are on top. You can use an ice cube tray, egg carton, dixie cups etc. (Some users report cutting up the screw guide and placing the applicable section in each container. One user reports printing a full page picture of upper case with all the different size screws, after keyboard, and poking the screws into the correct positions on the page as they were removed.)
• Be very careful pulling out leads. Hold the lead as close to the plug as possible and wiggle (the plug ) to loosen its grip. Don’t hold the wires and pull as that can damage the cable, or worse, in some instances pull the wires out of the plug. Indeed, some users have pulled the socket off the logic board! Use needle nose pliers or tweezers if you can access the plug, or nudge the plug with a small instrument to help loosen its grip.
• Use force gently in removing parts. Separating upper and lower case takes some doing. Use a plastic tool (spudge) so as not to leave marks.
• Refer to the screw guide when reassembling computer. Putting longer screws in the wrong place can perforate the circuit board.
Once you have the HDD installed you will need to format and erase the HDD prior to installing.
Formatting, Partitioning Erasing a Hard Disk Drive
• With computer shut down insert install disk in optical drive.
• Hit Power button and immediately after chime hold down the "C" key.
• Select language
• Go to the Utilities menu (Tiger) Installer menu (Panther & earlier) and launch Disk Utility.
• Select your HDD (manufacturer ID) in left side bar.
• Select Partition tab in main panel. (You are about to create a single partition volume.)
• (where available) Click on Options button
• Select Apple Partition Map (PPC Macs) or GUID Partition Table (Intel Macs)
• Click OK
• Select number of partition in pull-down menu above Volume diagram.
(Note 1: One partition is normally preferable for an internal HDD.)
• Type in name in Name field (usually Macintosh HD)
• Select Volume Format as Mac OS Extended (Journaled)
• Click Partition button at bottom of panel.
• Select Erase tab
• Select the sub-volume (indented) under Manufacturer ID (usually Macintosh HD).
• Check to be sure your Volume Name and Volume Format are correct.
• Click Erase button
• Quit Disk Utility.
Your HDD is now ready for either a fresh install of the OS and restoring from backup, or, if you have a previous installation that is sound, you can clone back to your new HDD. Post back for step by step directions.

Exernal HDD question

Hi guys. I have a Mac Mini and I will buy a MacBook Pro and another Mac Mini very soon. I have tons and tons of music (iTunes Music Store files, as well as MP3s from other online retailers, CDs, etc) and photos. In order to keep some sanity I went and bought an external HDD to store my files on as a safe haven and help keep the same files on every computer...
My question is what is a really good external HDD? I bought a Western Digital My Book Premium Edition 400GB external HDD. It is 7,200 RPM and has 16MB Cache. Best part was, it was $200 @ Best Buy. I think that is a pretty good HDD and a pretty good deal, but wanted to hear what you all had to say.
Also, once I have the correct external HDD, how do I use it among various Macs? Do I need to format it? Do I just treat it as a device that needs to be mounted/ejected (i.e. like an iPod)? This particular model comes with some Google software. Do I install that? Will spotlight search my external HDD? If so, I wont install the Google software.
Thanks,
Keith

I've just orded one of the My Book drives (the 250GB version). I have a Lacie and another WD drive, which are not too bad. The Lacie does get very hot though.
If you are looking to share the drive with a number of computers, you could look at a network version external hard drive. Western Digital do one - http://www.westerndigital.com/en/products/Products.asp?DriveID=243
This would allow you to share files easily between all computers, if you're using all the macs on the same network.
I'm not sure if Spotlight searches network drives though, but someone here may be able to answer that better than I! Spotlight will search the drives if you connect them as USB or Firewire though. It's fast too, at least that's what I've found.
If you go for the non-network version, then you would eject it like an iPod within finder or by draging the drive on the desktop to the Trash.
I think the Google desktop search tool is Windows only.

NMH300 - Hdd question

i have installed 2 hdd on nmh300. the disk is the same and they are 2tb each.
if i put raid 1 - no problem, disk space is 2 tb
if i put raid 0 - no problem, disk space is 4 tb
if i put single disk - 2tb disk space and 1 disk is not used.
Now the question.
i can install 2 single disk and see them as 2 separate disk ? (as 2 unit for 2tb each?)
or the only chance to use the 2 disk is put up one of raid 1 or raid 0 ?
tnks for reply

The mediahub will only display the primary disk which is the disk on bay 1 its not like the NAS200 where you can see two individual disks when its set to JBOD configuration.
Cheers.

Apple TV and shared external HDD questions

I just ordered my 160gb Apple TV today. I can't wait to get it. I do have a few questions though.
Can the Apple TV sync and/or stream from an external HDD that is connected to the airport extreme and can it do this with the host PC and/or Mac with iTunes (I have both) turned off? Both computers access the same library shared on the external HDD.
If the above question can be done, can I buy music etc. from the apple tv directly and than have it sync to the external HDD first and then to the PC when powered on from the external HDD?
Hopefully these questions make sense.
Thanks,
Nathan

Bummer, thanks for the fast reply. I thought it may be possible because on the apple tv page on apple.com it has an ad touting the enhanced streaming capabilities when paired with the airport extreme and since the airport extreme allows you to add an external HDD to be available wirelessly and shared with multiple computers it would seem that the scenario I posted above would work.
If there are any other recommendations and or Tweaks to get close to this please let me know.
Maybe the update will add this functionality.

Cloning HDD question

Hi, I've got a 13" Macbook 2Ghz Intel Core 2 Duo with OSX 10.4 and I want to upgrade my HDD. I already know what drive I want, but my question lies in my means to the end. I understand I can clone my drive with disk utility (from the bootup disk) or super duper to an external drive. My current external drive does not fit my macbook, and the new drive does not have an external enclosure. Won't need the enclosure, I just wanted to save money. Can I clone my macbook drive to my external drive, then install my new drive in the macbook, and clone from the external to the new drive I just installed? It sounds simple enough, but I wanted to be sure. Also, which program would be easier with that extra step, if either? Once this is complete I plan to upgrade to Snow Leopard.

Yes you can clone to/from your existing external. Don't forget the step of preparing your new internal HD by formatting it Mac Extended (Journaled) with a GUID Partition Table.
I think SuperDuper! is easier and more user friendly. You can use the free/trial version for what you want to do.
If you have any more questions about the procedure, perhaps the answer is in [This Tutorial|http://www.macinstruct.com/node/130].

Toshiba Satellite P875-S7310 second HDD question

I just purchased a Toshiba Satellite P875-S7310 (http://us.toshiba.com/computers/laptops/satellite/P870/P875-S7310/) and was hoping to install a second hard drive (SSD) to improve load times and boot times. As I understand it is rather wasy to install a second SSD into the P875-S7102, as it has a second hard drive bay, but I'm unsure about the P875-S7310. Technical support hasn't been of much help to me so I figured the second place to ask would be here. Does the Toshiba Satellite P875-S7310 also have a second HDD bay or will I need to do something like remove the DVD drive and buy a HDD caddy to install a SSD into this laptop?
Thanks a ton if you can provide me with any information,
Nianni150

The problem with those spec sheets is that they don't list the P875-S7102 as having a second hard drive buy, but in in fact does. It also seems to be compatible with whatever the bios firmware is and allows a SSD to be run seperately.
For reference here is the second hard drive bay for the P875-S7102 that was confirmed on this forum to function. I've attached a picture of the back of the P875-S7102 I've ordered which seems to have the same configuration. I guess my question is if anyone knows whether or not the BIOS supports a secondary hard drive and if there is a SATA connection. I was hoping to buy the SSD now and have it arrive at the same time as the laptop. but I'm hesitant to do that since I'm unsure whether it will work or not.

Upgrading HDD question

I'm new to Macs, but I plan on replacing my stock 250gb HDD with a 320gb, 7200rpm hdd. The OS on my MAC is still pretty much stock, just downloaded all updates. So I have a few questions:
1. Is it worth cloning at this point? Or should I just go ahead and start from scratch with the replacement HDD?
2. Do I have to format my replacement HDD (pulling from a Dell), or will the OSX installer take care of all that?
3. I have heard that the MacPros do not "feel" the same or as well put together after it is taken apart to put in a new HDD. Is this true?
I think that's it for now. Thanks.

Well...I've heard that there's about a 40% performance gain according to some benchmarks, and the main program that I'll use will be Logic Studio to do music production. In order to run effects and many tracks, I'll be needing all the power I can get.
However, I'm unfamiliar with Logic (I'm coming from PC's Cakewalk Sonar), and if I won't see that much gain, it might not be worth the trouble.
Are you familiar with Logic?
Thanks again.
I use logic every day. Keeps me from make bad NFL bets (well 8-8 last week so not so much) and getting run over by the streetcars, and petting tigers.
If your job is running benchmarks then I guess that is critical. Using the mac as intended, e.g. a computer these things fall by the wayside as pretty unimportant.
Ex-Windowers are big on tinkering all the time, I guess because the whole Windows experience was so awful, tweaks became a part of life to survive, vs. just using the computer as a tool.
