Unable to recognize computers via target disk mode

I am trying to transfer files from my iBook G4 to my new intel-based iMac. I have successfully engaged my iBook in target disk mode (i.e. the firewire symbol moving around the screen) but my iMac does not recognize that the iBook is in target disk mode. I have tried adjusting the timing of target disk mode and connecting the firewire cable between the computers but nothing works. I have tried reversing roles and putting the iMac in target disk mode while trying to connect from my iBook G4 but I cannot establish a connection that way either.
I know the firewire ports on both computers function because I am able to connect to other peripherals via firewire. I am going back to the Apple Store today to get a replacement firewire cable just to make sure that isn't the issue. Does anyone have any ideas about what could be causing this issue or how to resolve it?
Both my laptop and iMac are running Mac OS X (10.4.10).
Thanks.

  • Help: Windows XP on MacBook Pro Boot Camp Partition via Target Disk Mode

    Firstly, let me lay out my situation. I have an old MacBook Pro (2,2) with a broken disk drive. It was dropped in its youth and can no longer read from or write to CDs or DVDs of any kind. I have just recently bought a new MacBook Pro to replace it (6,2) and am currently trying to convert the old computer into an XP machine through Boot Camp. I'd like to be able to do so without having to buy an external disk drive.
    After a clean install of OS X (10.6.3) onto the old machine, I successfully partition 85GB of space (although I previously attempted the same with a 32GB file system to no avail as well) for XP to be installed upon. Because I cannot boot my XP install disk directly from the broken disk drive, I then close Boot Camp Assistant and shut down the computer. I start it up in Target Disk Mode to be accessed from the new MacBook (6,2).
    Once the old MacBook is connected, I insert my XP install disk into the new MacBook (6,2) and boot from the disk. After allowing the XP (Professional) boot to load the install files, I arrow-key down to my 85GB partition (FAT32, named standard as "BOOTCAMP") on the old MacBook (2,2)'s hard drive and select it as the partition I would like to install to. This is where I am directed to a new boot window that tells me in a series of paragraphs that the XP installer cannot reach the selected partition for what seems to be a number of reasons. What it seems to be trying to say to me is that it cannot do a remote install of XP on a Target Disk Mode-connected machine, while not "knowing" that I am trying to do so. It's a similar message to the one that Boot Camp Assistant shows when one tries to create a Boot Camp partition on a machine that is being accessed via Target Disk Mode (Apple puts it much more clearly than Microsoft).
    I'd be perfectly content, albiet slightly vexed, to conclude here that it is not possible, shuttle over to the nearest Best Buy, and purchase an external disk drive if it weren't for one thing: I tried the same thing two weeks ago with Ubuntu 10.10 and it installed perfectly on the Boot Camp partition I had created then (I have since wiped all and installed OS X cleanly on the laptop).
    Here comes the point/questions:
    If the Ubuntu boot disk can access the partition, why can't the XP boot disk?
    Is there some way to convince the boot system that the drive is local, rather than being accessed via Target Disk Mode?
    Is there an easy solution that doesn't even require that, and will allow me to install to the disk over a firewire connection?
    If anyone's knowledgeable and/or brave enough to tackle this one, I'll be eternally grateful. Heck, I'll be grateful if anyone even attempts to tackle it.
    Thanks,

    Windows XP will only install from the optical drive. Target Disk Mode does not work with Windows volumes. Windows will not install from any external device.

  • Need Help Installing Snow Leopard onto a blank HD via Target Disk Mode

    Hey everyone.
    Recently I had the HD on my Black Macbook crash due to a mechanical failure. I have just purchased a new Hard Drive for my Macbook. It is completely blank other than the fact that I connected it to my girlfriend's White Macbook earlier today to create 2 partitions. I have a new copy of Snow Leopard that I want to install on it and was hoping someone could guide me through the process.
    What I have with me as of now is:
    One Black Macbook (UK bought) w/ Partitioned Blank HD and a non-functional Superdrive
    One White Macbook (US bought) running Tiger w/ working Superdrive that mounts the SL DVD
    FireWire Cable
    New Snow Leopard DVD
    My first attempt at this failed. I connected the two Macs with the FW cable and started up the Black Macbook in Target Disk mode. Both my HD partitions showed up on the White Macbook. I inserted the SL DVD into the White Macbook and when it mounted I clicked on install. Of course, now it thinks that I want to install SL on the White Macbook whereas I want to install it on the Black Macbook.
    I'm a college student without a working computer and with my finals coming up, I'm in deep trouble. I want to mention that my Black Macbook's Superdrive spits out _everything except for Movie DVDs and My Leopard Startup Disk._ It spins the SL DVD for a few seconds and spits it out as well. I'm wondering whether this might be an issue with the DVD region code on the SL DVD though I don't think that's it. My region code is currently set to Region 1 (US) where I purchased the Snow Leopard DVD off Amazon. I initially thought there was a problem with the DVD and CD lens in the drive and I bought a DVD/CD Lens Cleaner CD but I can't run it because the Superdrive spits that out too. I'm out of warranty on the Black Macbook so fixing the Superdrive is pretty much out of the question. I was under the impression that I would be able to install SL via Target Disk Mode without any hassles but boy was I ever so wrong.
    Is there any way that I can do this? I'm hoping someone here can help me out. Please do if you find the time to.

    By other computer, do you mean the White Macbook? So I should basically put the SL DVD in the White Macbook, restart with the C key held down? Is that right?
    Please pardon me if I'm being stupid.

  • Is it possible to install OSX on another computer via Target disk mode?

    Hello Again SCHPiLKAS!
    As roam posted, you cannot use the Intel MacBook install discs, on the PPC iBook.
    Additional info in these links.

    If the iBook meets the Panther System Requirements, and the Additional Panther System Requirements, and you have a Full Retail Version, of the Panther Install CDs, you can use Firewire Target Disk Mode, to install the system.
    The Panther discs should look, exactly like the images in the above links, and not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on them.

  • Backup w/ Time Machine via Target Disk Mode?

    So here's my situation, my computer is stuck on the grey screen of death, but it mounts fine in Target Disk Mode. Its been about 2 weeks since my last Time Machine backup, so I would like to recover the last two weeks of files. If I can do that, then I'll just wipe the HD and start with a fresh install, however, since I can't get it to start up, is it possible to backup my computer to my Time Machine backup using Target Disk Mode through my wife's computer? Any help is appreciated.
    (If not, then is it possible to run a time machine backup from single user mode?)
    Here's basically what I'm talking about:
    MBP (Target Disk Mode) > Wife's MacBook > External HD (Time Machine Backup)

    That may work, but you'll get a whole new, full backup, identified as belonging to the MacBook (since that's where TM would run, and the MBP would look like an external HD.)  Unless you exclude it, you'd also get the internal HD on the MacBook. So it will require a lot of space and time.
    There's no way to fool it into making an incremental backup.
    Or, use the same setup, but make a "clone" on a separate HD or partition, via the Restore tab of DIsk Utility, or one of the "cloning" apps: CarbonCopyCloner or SuperDuper. 

  • Installing Leopard from a PowerPC mac to an Intel mac via Target Disk mode

    I've just purchased Leopard, but thanks to the common and very annoying faulty MacBook Pro disk drive, I cannot even read the DVD, much less install from it. Before, the disk drive error never affected purchased DVDs, only the ability to read and burn to empty DVDs, but now, apparently, I can't even read Apples own disks.
    As the new system disk is Universal, would it be possible to start the installer form the cd on my sister's PowerPC mac (12' Powerbook), and install the system on my MacBook Pro's harddrive, mounted as a firewire drive, or would the installer automatically choose the PowerPC version, since it is launched on a PowerPC computer?
    And, if so, is there any way to tell the installer to install the Intel version of Leopard if I run it on a PowerPC computer?

    well, looks like I'll have to install Leopard through the Firewire Target Disk mode as my MacBook can't read the DVD. I would appreciate if someone could review the steps below to let me know if I am on the right track. The MacBook is the computer on which I want to load 10.5 and the iMac G5 (PowerPC chip) is the computer on which I will insert the DVD.
    - First question: Am I correct (see above) in saying that the MacBook is the Target computer?
    - Insert DVD in Host computer
    - Connect Target to Host using FW cable
    - Turn on Target computer press and hold T to launch in target mode
    - select DVD drive from disk options
    - this is where I get fuzzy, would I simply click the Install icon? And then what? Will the MacBook know to reboot in Target Mode or do I have to hold down T again?
    - anything else I am missing?
    Thanks.

  • Installing OS X on older laptop via Target Disk Mode.

    I've got a PowerBook G4 15" with a broken optical drive. It only has OS X 10.2 and OS 9, so we wish it could have tiger. I was wondering if I could use my macbook and a firewire cable with the powerbook to install from target disk mode.

    Ah, so you mean use the MacBook as, essentially, an external DVD drive? Good idea; I was getting dismayed as the only PPC macs I have around are
    -an iBook G3 with the entire top half ripped off (works though, great media center through VNC)
    -the aforementioned Titatium powerbook 15"
    -a smaller Aluminum powerbook 12" with a working DVD drive, but there's a DVD that refuses to eject inside it. It reads fine, but the case survived a mighty fall (before it was ours) so it can't eject.

  • Unable to Install via Firewire Target Disk Mode

    I'm having problems with installing Leopard 10.5 via Target Disk Mode. The 2 Macs I am using are a eMac 1.0GHz with 1GB RAM Running OS X 10.4.11 and a PowerMac QuickSilver 933MHz 896MB RAM Running OS X Server 10.4.11.
    The eMac's Combo Drive has gone south and won't read DVDs so I am putting the install DVD into the QuickSilver. If I start the QuickSilver in Target Mode I only see the QuickSilver's harddrive on the eMac and can't access the install DVD. If I put the eMac in Target Mode and boot up the QuickSilver using the Install DVD after I get through the language selection it says the QuickSilver isn't capable of installing it.
    Any suggestions would be helpful.
    Thanks

  • Disk startup full- can't boot normally. Now in target disk mode.

    Hello all, so here's my dilemma-
    My disk startup is full and now I am unable to boot my computer past the apple logo and the loading circle.
    Here's what I've tried,
    I am now in target disk mode attempting to transfer over my files to an external HD via a good computer and then wipe/restore the OS on my bad computer THEN transfer my files over to the bad(now good) computer however..... some of my files won't transfer, especially in my iphoto library (It's HUGE 82 gigs) & my very elaborate final cut pro projects that have taken me h o u r s to do.... For example, some video icons don't show up with a snapshot of the video as they are suppose to but instead they're shown with a a default video icon which almost makes me think they're damaged files but the thing is- I was just working with these files.. My comp passed all HD tests. I don't think it's damaged...I don't know what's going on. If I could just find a way to delete some files...especially from my trash(30 gigs in there) so I'm able to at least  boot properly, that would be great
    Is there anyway to retrieve these stubborn files via target disk mode or another option?
    Also do you maybe have an easier way for me to go about this entire process instead of transferring 500gb of data back and forth? I tried to access my trashcan via target disk mode and delete the 30 gigs I have in there but I was unable to delete it- and I do have "read and write" switched on.
    Thanks in Advance!! ANY help is appreciated. I'm at wits end here.

  • Safely copying files from Target Disk Mode to External USB. Advice?

    Just got a new iMac and transferred my system and important files to it from my old iMac. However, a partition on my old iMac has files I want to move to my new iMac so they can be included in Time Machine backups while others I want to move to another external hard drive since I have physical copies of most of those files elsewhere.
    I can connect my old iMac to the new via Target Disk mode and copy the critical files from Mac-to-Mac easily and quickly enough. What I want to know is if I’m safe to copy the other files from the TDM-connected iMac to a USB drive.
    I’ve read that having other devices connected to your Mac while another Mac is connected via TDM can result in corrupted files. Is this true? Is it unsafe to copy files from a TDM Mac to an external USB drive?
    If it is safe, is it best to connect the USB drive to the new Mac or to the old one while it’s in TDM? There’s a lot of data so I’m wondering about transfer times. One method would see files going over Firewire through the new iMac to a USB drive, while the other would go from TDM-connected Mac directly to a USB drive connected to its own USB port. That is:
    TDM iMac > New iMac > USB Drive connected to New iMac
    or
    TDM iMac > USB Drive connected to TDM iMac
    I have limited space on my internal drive and I also don’t want to copy-hop from TDM iMac to New iMac then copy from New iMac to USB drive. I'd like to go directly from old drive to external USB drive if it's safe.
    So I’m looking for advice on the best way to connect devices in order to cut down on copying time and number of copies, and to do it safely without corrupting data. Any advice is appreciated!

    I've used Migration Assistant already to move all of my immediately necessary data and settings over. This other data was on a separate partition and I'm unable to copy all of the data over to my new drive due to lack of space.
    Things are complicated by the fact that I need to change some of my externals over to Time Machine ready backups. Previously I was using 1 TB and a 2 TB drive for TM and another 2 TB drive for general backups/archiving. Now I need to juggle things around so that both 2 TB drives are for TM and the 1 TB is used for archiving.
    An important point I should have mentioned is that I can't use my old iMac normally due to a GPU problem that seizes the system up. This is the reason I can't just copy stuff directly from old iMac to external USBs.
    I'm interested to know if what I described above is safe and if there are any time savings or benefits for copying through my new iMac or connecting the externals directly to the old iMac in TDM.

  • 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.

  • Can't exit Target Disk Mode

    I tried to login to my brand new iMac (running Lion 10.7) via Target Disk Mode so as to transfer my data from my old machine. However, the passwords didn't work. This is not a disaster, however, I am now unable to exit Target Disk Mode. I have tried removing RAM and restarting holding down alt+cmd+R+P to reset the PRAM but it just goes straight back to Target Disk Mode. No matter whjat I do it goes back to Target Disk Mode with the padlock and opassword box. Any ideas anyone? Thanks very much.

    Is  it a USB or wireless KB?
    Does it boot to Single User Mode, CMD+s keys at bootup, if so try...

  • 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.

  • 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;

  • Powerbook DIED. Target Disk Mode Failed.

    I did everything under the sun short of bringing it to a mac service store. My computer was left whirring all night (I was not home) and the next day I found all the programs frozen so I did a hard shutdown. I haven't been able to reboot it past the gray apple screen since. Tried resetting PRAM, tried reinstalling from CD but it did not read the drive, tried disk utility from CD to "repair" drive but got errors, failed and could not continue. Diskwarrior didn't make a difference. Now I'm trying to transfer data via target disk mode to another mac. Connected firewire cable, rebooted holding down T, I see the yellow firewire icon bouncing around, but HOST computer does not see target drive. WHAT DO I DO?? What's going on? I was under the impression that target disk mode was foolproof in times like these. ANY suggestions would help. Thanks.

    Welcome to the Apple discussions.
    Unfortunately, it sounds like your hard drive has died. If disk utility from CD couldn't find it, and Disk Warrior couldn't find it, and firewire target disk mode can't find it .... these all point to a hard drive that crashed hard.
    You didn't say if you ran the Apple Hardware Test. Insert your first OS X DVD that came with your system (will say 'AHT Version x.x in small print on the label), and boot holding the option key down. Choose the Apple Hardware Test, click the arrow pointing to the right and follow directions. Did that confirm the diagnosis? If you have a TechTools program, that can do the same testing.
    If you have Applecare, go get a new drive. If you don't, consider buying your own drive and taking it to an Apple Authorized Service Provider to replace the drive (If you take it to Apple to pay for a replacement, they will usually keep your old drive, as a trade in towards the replacement drive - some people are bothered with this approach which anectdotally is not negotiable with Apple). Apple Authorized Service Providers can be found at http://www.apple.com/buy/locator/service/
    If you scan the discussions, people generally seem pleased with HItachi and Seagate drives, although other brands work too. Seagate has a 5 year warranty if that's a consideration. You'll want a drive with a parallel ATA interface (not Serial ATA which won't work). 5400rpm minimum speed although for a few bucks more you can get a faster 7200 rpm drive. Two sources of drives are OWC at http://www.macsales.com and Newegg at http://www.newegg.com .
