Quadra 800 and internal SCSI drive

Could somebody advise me whether I can replace the second internal SCSI drive in Quadra 800 (MacOS 7.5) with something bigger and newer? I have a new Seagate Cheetah 73Gb internal SCSI drive (68-pin). Is there any way to use it in the Quadra? Is there any adapter that could be used for that?

Yes, but.
The largest Volume supported on that Mac, provided you are running 7.5 or later, is 4 GB. So you would have to create about 19 partitions (Volumes) to use all the 73 GB. The full story is in this article about Standard Format -- Extended Format requires OS 8.1 or later:
8647- Macintosh: \[Standard] File System Specifications and Terms
Volume
A volume is either a full disk, or a section of a disk, partitioned into separate parts. If you partition a single drive then each partition is considered a volume.
The maximum volume size under System 6 and System 7 is 2 GB. System 7.5 increased that limit to 4 GB and System 7.5.2 (and later) increases that limit to 2 TB on some computers, including:
- any computer that came with System 7.5.2 or newer. \[your Quadra 800came with 7.1 and an enabler]
- any Macintosh computer with PCI slots.
That 68-pin drive likely could use wide transfers and much higher speeds, but can be made backward compatible through careful use of adapters. Alternatiively, you could install a NuBus card to connect to it directly.

Added a 2nd internal SCSI drive into my 7500/100 does not show up.

Hi.
I added a 2nd internal SCSI drive into my 7500/100. It does not show up on the desk top. I rebuild the desktop reset the cuda and ran SCSIProbe. The computer starts up on the newly added drive. No sign from the original drive. Please help.

there are jumpers on the drives that need to be properly set. Both drives are set with the terminating resistor on, one needs to be off. Carefully note nthe placement of the existing jumpers then remove the jumper from the drive in the middle connector.

Internal scsi drives on mac pro?

I have just received my Mac Pro, which will soon be put into use as the center of a commercial audio recording facility. I was under the impression that the SCSI drives I had been using in my aging MDD dual 1 GHZ would be port-able to the new box. But, after snooping around a little bit on the boards here, and looking into the machine itself, this appears not to be possible.
Is it true that ONLY SATA drives are compatible as internal drives in the new Macs?
If so, then I need to sort out my new drive configuration for the studio machine. For better or worse, my studio uses ProTools, which does not support RAID of any sort. So I'm left looking at sharing the internal SATA bus with the system drive, going with an external FW800 drive, or investing in an external SCSI drive (ugh).
Any thoughts would be welcome.
Thanks,

following up on this thread -
I purchased the external chassis recommended above and have compared transfer rates with the somewhat unscientific copy time test, from the desktop of the apple SATA boot drive to and between various other drives. It appears that the internal SATA 7200RPM drive I bought from OWC is outperforming the external (10000RPM) SCSI drives I have mounted in the enclosure. This seems odd to me. I'm not sure if the bus speed is being ratcheted down to accommodate the cabling (SCSI 3) or what. I appear to be getting roughly one third of the 160MB/S limit on the Ultra160 drive (the buffer size is 8MB on this drive as opposed to 16MB on the 7200 drive).
Theoretically, the bus throughput is higher on the SATA bus, but I thought that would be outweighed by the drive performance - that appears not to be true. It also appears that the SATA drive is FASTER on the duplication process than the SCSI drive, which leads me to believe that the rotation speed is being trumped by something else - buffer size perhaps?
Any thoughts would be welcome. Here are the results of my testing.

Duplicating 1.27GB .zip archive on the same drive:

Music/movies on external hard drive and internal hard drive

I moved my itune library to an external drive using the recommended method (consolidate, etc.) quite awhile ago. Everything is working fine with that. However, at some point, apparently when the external drive was not connected, new music and movies were downloaded into the library folder on the internal hard drive on my computer.
Now iTunes, although it displays the information about the files that are on the external hard drive, when I try to play them, I get the message that "the song could not be used because the original file could not be found. Would you like to locate it now?" I can play the song after I locate it on the external hard drive.
My questions:
1)Will I have to "locate" all of these items individually, or is there an easier way to do this? And, is there a way to avoid this problem in the future if I accidentally download an item when the external hard drive is not hooked up?
2)How do I move the files that are now on the internal hard drive to the library on the external hard drive so that iTunes recognizes them?
Thanks!

+However, at some point, apparently when the external drive was not connected,+
Either that, or Windows nicely changed the drive letter on th exHD when you plugged in another USB device like a digital camera or even your ipod. The exHD MUST be connected before you start itunes. It's just the way it's designed.
+1)Will I have to "locate" all of these items individually, or is there an easier way to do this? And, is there a way to avoid this problem in the future if I accidentally download an item when the external hard drive is not hooked up?+
If the drive letter changed from what it was before, all you have to do is assign the correct letter to your exHD permanently.

Make sure iteuns preferences > Advanced tab are set to have the iteuns folder on the exHD. Then run the library > consolidate command. itunes will move them over to the exHD without losing track of them,.
If you move them in Win Explorer, itunes will lose track.

Good choices, though a true SSD would be faster overall, though more expensive. That same drive is a lot cheaper on Amazon though.

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.

Powermac Dual 867 MHz Power PC and internal hard drive

I was just sold a Samsung sp2514n internal hard drive- 250GB 7200RPM 8MB Cache.
The problem is that after I installed it- my computer would not boot up. All I got is a folder with a question mark.
When I took it out- it booted up normally.
Before I upgraded, I was told that it would work in my computer?
Is there something I'm not doing- that needs to be done- or is it incompatible with my computer?
Thanks,

Hard Drive Speed Difference Between FireWire 800 and Internal Drive

Right now I have my entire 1.5 TB Lightroom photo library on an external drive connected to my new Mac Pro via FireWire 800. Will I experience dramatic or even noticeable speed improvements if I move this drive to one of the internal SATA hard drive bays in my Mac Pro?
I would likely buy a new drive and SuperDuper the external to this new drive I put in the Mac Pro.
Thanks,
Matt

SATA II 3Gb is only the controller bus and has almost nothing to do with actual individual drive speed. Confusing the bus interface with hard drive speeds is not a clear way to compare.
Just pull the drive out of the FW case is all you probably need to do. Actual FW800 is less than 80MB/sec and more like 72-75MB/sec - which is as slow as your hdd gets from slow inner tracks.
Other than green, most 1.5TB drives average minimum 75MB/sec to max 115 with average in mid-90s. And the first 1/2 of a drive is where best performance comes from.
The size of the data and media library, amont of free space, all play a role.
I think FW should be left to backups, an alternate boot volume, off line data.
If it was Aperture library, but otherwise SSD is not realistic or viable. Nobody uses RAM disks as they are inefficient.
I still find 10K VelociRaptor ($279 / 600GB) fast, smoother, more responsive, great for system and data drives, even if they are only 135MB/sec, or about what some of your 2TB drives can offer.
QUICK TAKES - A striped pair of Velociraptor 600G 10K HDDs matches the speed of one SSD. For less that the price of one 256G SSD, you can buy two 10K 600G Velociraptor HDDs. If you stripe them (RAID 0), you get the same sustained transfer speed as the SSD. http://www.barefeats.com/quick.html
If you are not already using all the internal drive bays, just nice to have them handy before going external. Also take a look at two other articles on Barefeats:

MPB, Fireface 800 and a 1TB drive, what next?¿?¿?¿

Hi
I just got a bare 1TB SATA HD WDC drive
I use this set up to record:
Computer: MBP 17" Hi Res
Interface: FireFace800.
*Options on Audio interface*: FW400/FW800
*Options on Computer*: USB, FW400/FW800, possibly SATA with a Xpress card.
+I know USB is un reliable and taxes the system, and for a Sata direct connection i will have to find a Xpress card that works with the MBP, if i am lucky.+
I was getting error after error before running of USB drives so i ran out and got this SATA drive here.
Now what i am asking here is what the best method i should use to get the most out of this drive., should i get a external sata to FW 800, or a Sata to Sata xpress for the computer, and shold i partition it as well?
Cheers

Thanks for your post!
Maybe i should get a enclosure with Firewire 800, 400, eSata and USB well as
In the mean time, i borrowed a very expensive one from our studio and i need to format this drive and at least load some sessions on it until i decide which enclosure.
--> So should i make a single GUIDE partition?
--> you guys reckon i go Sata Xpress card enclosure all the way and if so which ones would you recommend?

DVD and internal Sony Drive problems

Hi,
I noticed that there were a few people having problems with writing DVD's so here's my problem to add to the list.
SONY DVD RW DW-U21A:
Firmware Revision: AADB
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: No
I always use DVD-R.
This is the drive shipped with my mac and until a few weeks ago it worked fine. I then bought a batch of TDK DVDs (2x-16x speed) and none would write. Some of my older Sony DVDs wrote the same files absolutely fine. I thought it was a bad batch of TDK's and got my money back.
Now I've just bought some Imation discs (up to 16x compatible) and some BenQ (8x)- who make for a lot of large brand names. The Imations fail in every write and the BenQ's are fine.
As far as I know my drive is 8x compatible, so could this 16x compatibility be part of the problem even though the discs are meant to be able to be written at 8x, or is a firmware upgrade the way to go?
One more thing, the DVD shop asked me if I needed DVD's version 1 or 1.1. How would I find this out?
Any pointers in this direction would be most helpful if you reckon it is the 8x/16x thing as the lesser speeds are getting more difficult to come by.

Agreed -- we shouldn't be forced into buying new drives. I'm as frustrated as you are. Apple should work with Sony to get the firmware updates we need -- there should be no reason that the new 16x media can't be burned at 8x in our year-old G5 systems.
I tried again tonight with new 16x Fuji media in Studio Pro, and got the same error. However, some lower-end, big-box-computer-store 8x media burns just fine. As I type, I'm burning to some old Apple DVD 1x media I had lying around; it too is working just fine. Proves to me that it is only the newer 16x-capable media that fails in this drive (I think 5 different media vendors is enough to demonstrate this).
Did you also notice that it is (nearly) impossible to find brand-name 8x media in the stores today? I'd be happy if I could find that without mailorder. FYI -- a mailorder location where I have been successful is www.supermediastore.com -- I might have to order from them again.
I see that someone else has posted and mentioned macsales.com -- that is where I got the $43 price for the Pioneer burner.
I have no association with macsales.com or supermediastore.com -- just a satisfied customer in the past.

Quicksilver scsi drive size limit ?

Hello all.
The original 37gig SCSI drive on my Quicksilver (NOT mirror door) is beginning to sing a sad song so I am looking into replacement.
I know there is a 128gig size limit for ATA drives in this model but is there any size limit for internal SCSI ????
I have already added a 120gig ATA with my original 80gig ATA so I think I'm pretty well maxed out (heat and power wise) on internal ATA drives.
Due to the cost of SCSI drives I'm thinking what I may do is buy an external LARGE firewire dive, transfer the contents of my internal SCSI drive to that firewire drive and then just use the SCSI drive as a dedicated "video capture" drive until it finally dies.
So, besides the original question about SCSI drive size limits does anyone have anythoughts on going external firewire vs. additional internal drives?
Thanks.
Gary

Hello! If speed is an issue get a sata Raptor drive (most 36 or 80 gigs). The access time is as fast as a 10,000 rpm scsi drive. Just add a sata card to use the sata drive. Tom

Can I clone and transfer from the internal hard drive to an external hard drive ?

I got an intel duo iMac, the machine is very good even if it is almost 3 years old. But with the internal hard drive having 320 Gb I am running out of hard drive space. I have looked into changing the internal hard drive but that involves having to send the machine away to have that done. So I was wondering if I could just transfer all the Mac OS X and all the applications and settings within three user accounts to say a 2 TB external hard drive, and boot from that, using cloning software.
Alternatively, is there a way to transfer the iPhoto and iMovie libraries to an external hard drive. That would free up space. I do not know how, if that is possible, although I have managed that with iTunes. My iMac is running Snow Leopard.
Regards from John5801

John,
USB should be fine for general computer use, but media may add a little too much for the sustained rate that USB2 provides. In a previous career I did a lot of video editing. Firewire was much preferred in that task because of its stability at higher rates. I can see why the SuperDuper! people might suggest it.
When I cloned the wife's iMac, I had replaced the HDD on the MacBook Pro with a USB pocket drive that I've kept the original MacBook's installation mounted on. I've booted directly to that external drive, so you should be okay if you can make the clone across the USB. When I cloned the wife's machine I booted the MacBook Pro with a fresh HDD in Firewire target mode and connected it as an external Firewire 800 drive. Firewire 800 is much faster, but you'll need the cable and everything to be right.
Firewire has a better reputation among people running a lot of media from their drive. I would suggest that you try and get an external drive kit that can support both. I think your iMac supports both firewire 400 AND firewire 800 along with the 3 USB2 ports. I'm guessing based on my wife's 24" imac. The fastest would be the Firewire 800, but that standard is about to be pushed aside in both cases.
Hope that helped.

OS 8.1 - Trying to partition an external scsi drive and backup data.

Have an Apple PowerMac 6000 series minitower at work. It runs a program called 4D, that is a database we use to catalog images. Since I've been with the company, there has been no backup of the database, as an external scsi drive had died and never been replaced.
Since the system is running OS 8.1, I wasn't sure how I could do any sort of network backup, and in the end I managed to get a new 50-pin scsi 50GB LaCie External Hard drive with the 25-pin cable to connect to the PowerMac. Connected it yesterday, and it did appear on the desktop as you'd expect.
But when I went to point 4D to the drive, it didn't seem to recognize the file system. I tried erasing the drive, but it had the same probem. Norton Utilities is on the mac, so I tried replacing the partition. Specifically, I tried creating two partitions. One that's 40GB, that I could do 4D backups to. The other, the remaining space (about 7GB) so I could try to copy the entire drive to that partition and maybe even boot from it if the other drive failed.
However, the drive was still mounted when I tried to repartition and it ended up causing an error. I tried rebooting, and the drive wasn't showing on the desktop, but it still wouldn't repartition. Not knowing was else to do, I low level formatted the drive, told it to write zeros to it, and then create the two partitions. Given I was doing all this on a Saturday and didn't know how long it would take, I left it running in the background to check on Monday.
Anyone have any experience with OS 8.1? Is there a program like Carbon Copy Cloner that works with that OS? And any thoughts on what I'd need to do to get this drive working as indicated above? I started using Apple again with OS X, and it's quite a bit different than 9 and previous. Could sure use some help.

Hi, merkman2001 -
I would use the Apple utility Drive Setup (which comes with a normal OS 8.1 install) to initialize and partition the drive, rather than Norton or any other third-party utility.
As far as the format type goes, select Mac OS Extended when asked.
<hr>
Is there a program like Carbon Copy Cloner that works with that OS?
Generally such is not needed with OS 9 and earlier OS versions. All pre-OSX OS's and software can be copied using a Finder (drag and drop) copy process, and remain usable.
This means that the System Folder on the internal drive can be dragged to the icon of the external drive and dropped into it. Ditto any/all additional folders, those containing the programs and documents.
You should be able to successfully do a test boot using the freshly-copied OS on the external drive; this is the best way to verify the integrity of the copied OS.
Can't recall if aliases were used in OS 8.1. If they were, it may be necessary to 'fix' any of them used, since the pathname contained in an alias is not corrected when it is copied to another drive - it continues to point to the original original.
You can also copy the entire source drive to the external one in one action - drag the iccon of the internal drive to that of the external one and drop it in.
After Finder gets done copying everything (this may take some time, so disable any sleep mode or screensaver), there will be a new folder on the external volume - this folder will be named the same as the internal drive. Inside that folder will be a copy of everything that was on the internal drive, including everything left lying around on the desktop and anything left unemptied in the Trash (these will be placed in new folders named "Desktop" and "Trash" respectively).
In order to make that external volume bootable using the freshly copied OS, move the System Folder out of the folder it was copied into, so that it is at the root level of the drive, meaning visible in the window that appears when you first open the drive's icon.
