Internal Drive Performs Strangely in Target Disk Mode

I am trying to use one of my internal HDs on my MacPro Mac Pro (2x3 GHz Quad-Core Intel Xeon) as a destination for a HD clone using SuperDuper.
I startup my MacPro in Target Disk mode using FW800 cable and 2 of my internal HDs show up instantly. My 3rd internal HD shows up after maybe 3 minutes for some reason. When I select it as a destination using SuperDuper, the files just don't want to copy at an acceptable speed and the app eventually errors out. Why would one internal HD not work in Target Disk mode when the 2 others do? The HD works fine when I access it from my MacPro and DIsk Utility returns no errors on the drive.
Here is the internal HD info:

Hi, problem solved! Thanks very much for the help. As soon as I opened up the G4 I remembered what the back of the hard drives looked like and after quickly changing the jumper blocks and hooking the computer back up everything worked as you said it would. Again, thanks! I am curious, though, is there no way to have both drives show up while in Firewire mode. It's no big deal, the migration assistant seems to have worked flawlessly but it might be handy to have both drives show later if it's possible.

Data recovery options if drive not accessible through Target Disk Mode

I have the classic data recovery question: my computer seems to have failed, and I'd like to save some data. Thanks in advance for any advice.
Details:
- Most recent backup was about a month ago to Time Machine (unfortunately, this laptop went off on a long trip and didn't have access to the destination disk, and then when it came home was running very slowly and my wife halted the TM backup thinking it was slowing the computer down). Some documents have been backed up more recently via Dropbox and/or Mozy, but not a couple important ones
- When booted in Target Disk Mode, no drive shows up on the computer to which I connect it
- When I boot from an OS X CD, a drive appears in Disk Utility with no volumes on it, and the options to 'repair disk' and 'verify disk' are greyed out.
- When I try to just start the computer up, it gets to the grey screen with the apple and just spins.
Questions:
- Should I attempt anything else myself? I've never learned about Lion's Recovery Mode; can it be used to copy some data off, in the unlikely case that this computer would boot into that Mode? Would any further attempts to boot, etc. potentially reduce the chances of a professional company recovering data?
- I'm planning to take this to an Apple Store today to confirm that this is indeed a hard drive problem and not a failed mother board or something; is there a way for me to do this myself? In the past I've used Hardware Test CDs from Apple and stuff; I don't know if those still work on modern computers.
Thanks again for any help!

I know I used to have a copy of Disk Warrior, but can't find it and it's probably out of date. I downloaded the Data Rescue demo, but it only got partway through scanning the disk and then failed. It told me to 'clone' the disk, but after about three days of trying still wasn't making much progress on it, so I gave up.
However, I was able to recover the few important files I needed simply by removing the drive, putting it in an enclosure, and connecting it via USB. After 10 or 20 minutes, Finder gave me a message that said something like, "this disk cannot be repaired, and is probably damaged. You can still access the disk, but copy everything off ASAP because it will probably fail soon." Some files indeed couldn't be copied, but I could copy the things I needed.
I assume that this is a hardware problem. To confirm, I assume that I can check it without having DiskWarrior simply by trying to reformat it? If it can't be reformatted, I assume there's no chance that it is a functioning drive. Is that right?

Mac mini doesn't recognise Powerbook G4 in Target Disk mode

The hard disk on my Powerbook G4 is reporting errors so I would like to get the data off it by connecting it to my mini in target disk mode with a firewire cable.
The powerbook drive fires up into target disk mode but the mini doesn't seem to recognise it. Anyone else had this problem and solved it?
Thanks in advance.

Hi,
Thanks for your reply, I cannot get startup manager to come up unfortunately, I have tried trying to get startup to take place with the 10.4 bootup DVD, but couldn't get that to work either. I am thinking of resorting to using DiskWarrior DVD to load from it and see what I can salvage....

Target Disk Mode Installation

I have an iBook (doesn't have a DVD drive) that I would like to install Leopard on from my DVD installation disk. Since the iBook's HD only has 1 partition, is it possible to do an Erase and Install while in target disk mode using another computer's DVD drive? I am concerned that erasing the HD will have some effect on the computer's ability to stay in target disk mode.

From the host computer, launch Disk Utility.app, and select the hard drive you have in target disk mode from the list to the left. Click the Partitions tab, then Options. You should be able to select "GUID Partition Scheme". Now is also a good time to name the hard drive; name it "Macintosh HD". Click on the Partition button again to apply the changes. Quit Disk Utility, and follow the prompts from the installation disc, selecting the iBook as the destination volume for installation.

HT1661 Problems mounting Imac in target disk mode on retina laptop with a solid state drive as host

I'm trying to use an Imac in target disk mode to copy files from it to a new retina display laptop with a solid state drive, but the target drive will not mount even tho it does start in target disk mode. I have all the proper firewire connection. The Imac will not respond for more than a few minutes before crashing when started from its own system. I would like to salvage a few files from it before I perform a clean install of the system.
Anyone has any idea why it wont mount in Target mode onto the retina laptop? Help!
Thanks in advance. :-)

Mac OS X doesn't offer a "clean install" option.
I'm assuming your target Mac is running 10.6?
And you setup the target Mac without adding a Firewire cable until after the Firewire logo appears on the screen?

Firewire Target Disk Mode - Secondary Internal HDD?

Hello great collective of knowledge.
Does anyone know if there is a way to target the secondary internal hard disk in Firewire Target Disk Mode?
Thanks,
Clint

FireWire Target Disk Mode will only work with the master Ultra ATA drive. To access other drives, change the position of them in the computer or use File Sharing, with SharePoints if necessary.

Firewire target disk mode only recognizes 128GB of my 400 GB external drive

I am using an old Powermac G4 with a Seagate 400MB internal secondary drive as a n external drive via firewire target disk mode. I have used disk utility to format it but only 128 GB of the 400 GB is recognized? Any thoughts?

More than likely your old G4 has a disk controller only capable or recognizing drives up to 128Gb size. If it's an original G4 model with no additional ATA card in it, that would be normal.

Old G4 450 Sawtooth - Multiple Drives - Target Disk Mode ?

So I have had this old computer a long time and have upgraded it over the years as much as it can handle - faster processor, max ram, multiple drives ...
The problem I am having at the moment is only one of the drives will show up in TDM - the one that shows up is the original 20Gb drive. I have a Seagate 500Gb and another Seagate 1.5 Tb drive too. Neither of the Seagates show up in TDM. I haven't cracked it open in a while but seem to remember they are connected via a SATA controller card. Just verified the two SATA connections. The 500Gb drive is my boot drive.
So is there something obvious here that I should understand? Thank you.
Oh I'm connecting to a circa 2007 MBP and Mavericks. The G4 is running Leopard.

I think I found my answer .... unless someone has an idea or info otherwise.
Tip: FireWire Target Disk Mode works on internal ATA drives only. Target Disk Mode only connects to the master ATA drive on the Ultra ATA bus. It will not connect to Slave ATA, ATAPI or SCSI drives.
Doesn't mention SATA but inferring it does include SATA.

Firewire Drives not showing and no Target disk mode

Strange problem. My two g4 450's one dual and one single will not start in Target disk mode, will not recognize Firewire drives and yet WILL recognize my iSight camera. What's going on?
Have 6 different drives to choose from but none mount. They all work on my G5 & MDD Dual
Enio

PROBLEM AND SOLUTION:
One computer does not recognize the other, which was booted into Firewire Target Disk Mode (either by holding the T key on start up, or by selecting FTDM in system preferences as the start up mode).
My particular case: older MBP to newer MBP unibody. I have a cable that is firewire 400 with a firewire 800 tip on the other end (6-9 pin cable). This cable is needed, for instance, if you machine only has firewire 400 but your new machine only has firewire 800 (like the new Unibody MBP). Well, they sold me this 6-9 pin cable at the store, when they should have just given me a firewire 800 cable straight across, because both machines have FW 800. Anyway, I tried the 6-9 pin cable, where the old MBP was connected via its 400 port to the Unibody's 800 port.
No dice. Would not mount, nothing. Repeated restarts, checked the cable and it does work... called Apple tech support, nothing. Researched the web until finally I think I know what it is.
There is not enough power coming from the 400 port to power the 800 port. I tried this 400-800 with my new Mac Mini as well, and it does not work. It does, however, get picked up on the older MBP when using a straight FW 400 cable. I then came across an article saying that someone was told by Apple that the FW bus can, in some machines, not provide enough power for FWTD mode. The solution for 400-800 is to go 800-800, or 400-400 if you can. If these latter don't work (FWTD mode fails to mount the connected computer's hard drive), us a powered firewire hub and connect Computer A to it, then connecting the hub to Computer B.

Target disk mode opticle drive?

My ibook g3 cd drive is broken and my external drive is having problems booting from install discs. The iMac boots them fine. I have an iBook g4 that will do this but its dads laptop. I need to install mac os x 10.1 (which will not mount external drives on installation) on the iBook g3 (there is somthing wrong with the mother board, it runs tiger worse than the iMac which has less ram.)
my point is is how can I use the iMac g3 opticle drive on the ibook g3 with target disk mode?

I don't think you can do it that way, if you are using the iMac in target mode. According to this document
http://support.apple.com/kb/HT1661
"FireWire Target Disk Mode works on internal ATA drives only. Target Disk Mode only connects to the master ATA drive on the Ultra ATA bus..."
On the slot-loader iMac G3, the optical drive is the slave drive on the ATA bus. The hard drive is obviously master. So only the internal hard drive can be seen by the host computer.
You may be able to do it as follows. Start the iBook in FireWire Target Disk Mode. Connect it do the iMac running normally. The iBook's hard drive should show up on the iMac's desktop as an external FireWire drive. If so, insert the Mac OS X 10.1 installation disc. Restart with the C key held down to start up from the iMac's optical drive. Run the installation using the iMac and target the iBook's hard drive for the installation. Once installation completes, and after the initial restart, shut down both computers and try to restart the iBook normally, from the new 10.1 installation.

Target disk mode with external hard drive?

Hi all,
I have a very annoying problem. I've just bought a new Mac Mini, previously I had an iBook G4 600 (about 6 years old). My Mac mini works perfectly, but...
1) I don't want to copy everything over from the iBook with Migration Assistant, I'd rather pick and choose what to copy. Is buying a firewire cable and using Target Disk mode the only quick way to do this?
2) I was intending to transfer files using my external HD. But the Mini doesn't recognise my poor old external drive. However, all my iTunes music is on the external HD. It seems by far the fastest way to get the music off (as long as I can't get the mini to recognise the HD)would be to boot the iBook in Target Disk mode then somehow be able to read from the external HD as well. Is this possible? If not, what on earth can I do??
Thanks in advance,
Suz

Okay after testing, I am ready to conceded that you are correct that you can daisy chain an external drive and a TDM Mac together and have them mount both drives.
However. unless Suz proves me wrong (Which is always a possibility), I do not think that it will fix her initial problem. Since all's TDM does is allow the computer to act as a Firewire device, so it and the external hard drive, are simply 2 FW devices on a serial bus. If the new Mac Can't mount the external drive from the old computer, I doubt it would mount it with the old computer connected to it. (Unless there is just some funky thing going on that having another firewire device on the bus corrects?)
Let's see if it shows up in System profiler, and if it shows up there how does Disk Utility see it?
Have you also tried resetting the NVRAM?
Also just to be on the safe side, do you have another Firewire device that you can connect, to let us know that the port on the new mac is actually working?

Using Target disk mode from hard drive which is starting to fail, when I move files, I get a preparing to copy message but nothing happens. Any ideas?

Hello, i have a MacBook Pro. The hard drive is failing to such an extent that I can't currently use the computer, only things like utility mode etc. I have connected it unto my iMac and using a Firewire in target disk mode, I am attempting to move files across using that mode. The HD of the Macbook Pro appears in the IMac devices menu and I copy and paste the appropriate folders/files but as I do this I get a progress bar which says "preparing to copy" but then nothing appears to happen. Any ideas on what to do? Is there a password or other issue here that I am over-looking. Perhaps the hard drive of my macbook pro is so corrupted that I can't move files over. Any help would be great?

Try moving smaller groups of files. I' guessing that you don't have a backup huh?

Can you install tiger on a power mac g4 with out a DVD drive if so how, I do have have a 2011 iMac can I use that in target disk mode with a FireWire cable any help would be appreciated

Can you install tiger on a power mac g4 with out a DVD drive if so how, I do have have a 2011 iMac can I use that in target disk mode with a FireWire cable any help would be appreciated

Hello,
You need to put the Tiger Install Disc in the 2011 iMac, boot the 2011 uMac into Target mode...
http://support.apple.com/kb/HT1661
Boot the G4 holding the Option or alt key, hopefully the Install Disc in the 2011 iMac will show as a boot choice.
We just want to use the 2011 iMac as a big expensive FW Optical drive, it cannot be installed osing the 2011 iMac itself.

Firewire target Disk mode-accessing second hard drive

When linking two computers in Target Disk Mode I find that I can only access the boot drive. In the computer that I'm accessing there are two drives. Is there any way to access the second drive?

Appleshare networking would take about as long as installing OS X on another hard drive. Although an external drive case would be the easiest solution.
This is a case I bought a while back, its very easy to install or change hard drives;

Something annoying this way comes: using targeted disk mode for boot drive

So, this should be doable, but it's not working. Can anyone explain why, or what I'm doing wrong?
I have an Intel iMac, and an Intel MacBook - both are running Leopard. I temporarily want to use the iMac as the workstation, and the MacBook as the operating system hard disk. So, I put the MacBook in targeted disk mode, and connected it to the iMac via firewire 400. From the iMac, I option-booted to see the available boot disks. I then selected the MacBook's disk and clicked the arrow icon to boot. Once the iMac attempts booting, it displays the spinning cog on gray screen for longer than usual, then goes to a blue screen with an intermittent spinning cog. It seems to hang at this point.
I've done this with PPC machines in the past, so I'm not sure what the deal his here. The only things I can think of that would be a problem, but really shouldn't be are: 1) the MacBook is running 10.5.2 (keeping it at v2 due to the CS3 issue) and the iMac is running 10.5.3. Also, the iMac is the 24" model - so perhaps there's a screen resolution issue...
Any advice out there? THANK YOU!

Hi
Presumably the version of Leopard on both models are hardware specific? I would have thought extensions for device specific hardware such as graphics drivers etc on the Macbook would not include support for the 24" iMac. Bigger screen, more resolution support and a more powerful graphics card.
If you were to go the other way I can imagine the driver included for the iMac 24' would probably support the smaller Macbook screen.
I don't have any link or kbase that I can point at to prove this 'theory' because thats all it is - a theory. But it kind of makes sense to me and does explain the behaviour you see.
