Problem With Target Disk Mode

Folowing upgrade of my Mini and Powerbook to Tiger I have a problem with target Disk Mode when I attempt to eject the transfer to disk following transfer of my user file. I get an error message to the effect that files are in use and the disk can not be ejected. I try force quit (finder only is running) usually to no effect. Sometimes attempting to verify disk permissions in disk utility will clear the problem and allow me to eject the disk. One time it took close to an hour attempting to eject the disk. Is there another way?

I had this problem with external volumes like ZIP discs and also external hard drives. Sometimes it was an app used on one of the external files still being open (eg. Word for a text file) which had to be quitted first. The "trackpad" button equals the mouse button which is on the PowerBook. Repairing the target disk via disk utility might also help.

  • Broken Macbook Pro won't finish copying even with target disk mode. Help!

    Hi,
    I'm helping someone with a Macbook Pro 2010-11. It worked for a few years but eventually degraded last month when it wouldn't go 10 minutes without displaying the rainbow loading ball. Possibly a hard drive problem.
    The owner never backed any of the computer up. I am trying to salvage their data before it's lost. The computer can power on. I have been turning the computer on and salvaging most of the data from numerous trips with USBs until it crashes, and then moving on to Target Disk Mode. The computer turns on slowly, displays the rainbow ball every minute or so, and never finishes copying or exporting anything. It still seems to be degrading.
    I still need two things: One is a large folder with thousands of old OUTLOOK e-mails created on an old PC (which the owner no longer has).
    Second is the folder/autobackup where OUTLOOK for Mac stores all the e-mails and settings.
    I have found the folder -- I think it is the Main Identity or Office Identities. Am I correct? Will this bring back OUTLOOK on the newer Macbook Pro exactly like on the old one? I also know where the old e-mails folder is, but when I try to transfer either folder through Target Disk Mode on the newer Macbook Pro, it stops and gives me the "Some data in _____.olk14msgsource could not be read or written." AKA error code -36, halfway through the transfer.
    I have tried exporting OUTLOOK on the broken Macbook Pro to a .olm, but it gets stuck halfway and gets stuck back on the rainbow ball. Then I shut the computer off. I have also tried going into the folders through target disk mode and deleting the .olk14msgsource files that are problematic, but there are too many of them.
    Please help! The owner needs these files and OUTLOOK exactly like it was!
    Thanks!

    Tried connecting the cable?  Still won't start?
    If you are still under warranty and/or have AC, call them & let them deal w/it.
    OOW:  Take the MBP to your local AS or an AASP.  Diagnostic testing is FREE!

  • Help with Target Disk Mode

    I'm having some problems starting up a Power Mac G4 into target disk mode. I've done it before, a couple weeks ago, but now every time I try it instead starts up into open firmware mode. I can't figure out what's going on, any help would be greatly appreciated.

    Welcome to the forum.
    Firstly, let's check a few things. Have a look at APPLE'S KNOWLEDGE BASE on how to do it. If that's what you're doing then report back.

  • Anyone else having problems with Target display mode on Mavericks?

    Hi,
    Last week I upgraded my iMac and macmini to Mavericks.  I use target display mode to use the iMac display for the macmini.
    Since the upgrade I have suffered problems with winow resizing as I swap between computers.
    In particular I notice it with the Eclipse IDE window - since I am using the two systems for dual development projects.  But I don't believe the problem is limited to Eclipse,
    What happens is that when I switch (with fn-f2) the window appears to have disappered, but usually after bringing various apps to the front re-appears as long window with zero height (just the title bar).
    Am I alone in this?

    No - I'm having issues with my Macbook air -- working with Apple right now to figure it out. will let you know if I figure out a solution.

  • Problem with Target Display Mode

    Hi there
    I just bought a nice new 2013 27-inch iMac and want to use my old late 2009 27-inch iMac as a second display. The new iMac has 2 Thunderbolt ports and the older one has a MiniDisplay port (the connectors are the same). I bought a Thunderbolt cable to connect the two, as I read that the new iMac can connect to older Macs through the MiniDisplay port. When I hit FN-CMD-F2 or just CMD-F2 nothing happens, and I cannot get the older iMac to serve as a second display. I have shut down and restarted, unplugged all other peripherals, and checked the cables are inserted the right way, etc, etc.
    Interestingly, when I use the brand-new Thunderbolt cable to connect my two MacBook Airs (both of which have Thunderbolt ports), I can't get Target Display mode (FN-CMD-F2/CMD-F2) to work either.
    So, do I need a male-to-male Mini Display to Mini-Display cable instead, or some other sort of connectors to allow the older iMac to work as a second display?
    Thanks
    Jon

    OK, I will try that. Still not sure why Target Display Mode doesn't work with the two laptops though. Target _Disk_ mode works fine with them, when they are connected both ports show as 'connected' under About This Mac/More Info/System Report, but (FN)F2_CMD does nothing...

  • How do I back up the Mac Pro with Target Disk Mode?

    My Mac Pro's partition has become corrupt, and will not boot. After trying to resolve the issue, it would seem the only solution is to reformat the computer, and start again.
    Nonetheless, I would still like to back it up. I have a MacBook Pro, a firewire cable, and an external hard drive connected to my MacBook. The partition is showing on the MacBook. However, Time Machine cannot back it up - It only sees my MacBook's partition.
    Is there any program I can use, or heck, anyway with just Mac OS-X on the MacBook I could use to back up the Mac Pro partition?
    Also, when I format the Mac Partition, I assume the Windows Partition will also be formatted? The Windows XP partition is working fine at the moment.
    Message was edited by: Christopher.Foss

    to be on the safe side. I would back up both partitions. that being said, if you try to erase the mac partition it shouldn't erase the pc partition. if that fails you could try deleting the mac partition and then re-adding it.
    But if the drive is really scrambled you may have to re-partition the whole drive; witch would erase every thing.
    You could try using disk utility to copy the drive as a disk image:
    http://support.apple.com/kb/ht1553 explains how to do this in section "Instructions for backing up to an external hard disk via Disk Utility"
    if disk utility fails you could try:
    you could try carbon copy cloner

  • 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.

  • 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?

  • Startup problem after use in target disk mode with a PC. Ideas?

    I used my Mac 10.4 in traget disk mode. Data transfers between Mac and PC worked fine (via Macdrive 6). After disconnecting and trying to boot normally, Mac doesn't recognize internal volume. It flashes the question mark.
    Tried to repair disk via install DVD - disk utility found no problems.
    Reapired permissons.
    Reset PRAM and NVRAM.
    Tried Startup utility - found the internal volume and even after selecting it for startup, I still get the flashing question mark.
    Apple hardware test found no problems.
    Archive and reinstall is not allowed.
    Data can still be accessed fine via target disk mode.
    Any ideas how to reinitialize or reset the startup volume?

  • 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
    Message was edited by: 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?

  • MBP and target disk mode with PPC desktop

    I am thinking about finally jumping to a MBP from a PowerBook.
    One of the things I do a lot is hook up my PowerBook in target disk mode to interchange information with my PowerPC desktop.
    Any problems with using a MBP in target disk mode with a PPC desktop? If so... what???
    Thanks for any feedback, help, cautions.
    -- Jim
    Powerbook 15 1.67ghz High Res DDR2   Mac OS X (10.4.6)   1.5gb ram, 80gb

    We just took the plunge and our MBP is being shipped.
    Did you let the Migration Assistant move your applications? I am thinking about whether it is a good idea to migrate Final Cut Studio and any other non-Universal apps, for example, from the PowerBook, then get the Universal upgrades? Or just get the Universal versions and install them?
    thanks

  • Can't get Target Disk Mode to work with host computer

    Here's the problem. My Powerbook G4 went down a week ago (it's 7 years old) and I suspect the problem is either the hard drive or the portion of the logic board controlling the drive. I also have a Power Mac G4 400 that's running OS 10.4 Tiger. I've been trying to extract some files (that I failed to back up) from the Powerbook via Target Disk Mode using the older Power Mac as the host, however the target disk doesn't show up on the host screen. When I boot up the Powerbook holding the T key, it chimes and the FireWire symbol shows up like it's suppose to, but that's as far as goes. I plan on upgrading to a newer Mac, which would probably work better as a host, but money is a bit tight right now. Any suggestions would be appreciated.

    If the trouble with the Powerbook is either a failed hard drive or a failed hard drive controller, FireWire Target Disk Mode isn't likely to work with any host computer. What you may want to try is installing data recovery software on the desktop G4 and seeing whether it can see the Powerbook's drive (connected in FWTDM) even though it won't mount. Data recovery software is often able to salvage data from drives that won't mount normally; it may be able to do the same thing via FWTDM.
    These three DR utilities are all available in free downloadable demo versions that will show you what the full version would be able to recover before you have to pay for anything:
    Data Rescue
    FileSalvage
    VirtualLab
    Good luck.

  • Slow transfers with G5 client running in target disk mode

    I'm using a brand new dual 3GHz Mac Pro, just arrived today.
    I've connected my G5 in FW800 target disk mode, it's two internal drives are mounted properly on my Mac Pro ("/Volumes/Files 1" is the drive in the G5):
    /dev/disk3 750G 98G 652G 13% /Volumes/Files
    /dev/disk4s3 400G 334G 66G 83% /Volumes/Files 1
    I'm copying all my old data, and it's taking way too long.
    iostat reveals disk activity on disk4 at 10MB/s (it never passed 11MB/s - it's always upwards of 10.5MB/s, so it's being throttled):
    disk4 disk5 disk1 cpu
    KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us sy id

    There are always 128KB/t when a large file is being copied, so perhaps that's the rate limiter.
    iostat will not print statistics about "disk3", which is the destination RAID1 (mirror) inside the new MacPro. What tools are used to monitor IO stats for Apple's RAID volumes, if iostat won't do it?
    I'm open to suggestions as to what's causing this. I don't know much about tuning MacOS. Is this a firmware issue? The MacPro firmware is up to date (did it today).
    There are no other FW devices connected, period. This is just the G5 connected to the MacPro; FW800.
    I have read articles discussing problems with slave drives not being available from disk mode clients, but this is not that type of problem. As I mentioned, the drives in the G5 all mount correctly on the MacPro.
    Should I post this in a G5 forum as well?
    Thanks for any suggestions.

    I am having the same issue - extremely slow transfer speeds from old G5 to new MacPro. Was originally using a FW400 cable - now I am using a FW800 cable.
    Goes VERY slow when it starts moving video files (from Final Cut Pro, etc.).
    Help! We've been trying to do this transfer for about two days now...
