No write access to Target Disk (in target disk mode of another Leopard)

Every time I connect my MacBook to my iMac using firewire target disk mode (iMac in control, MacBook in target disk mode), I only ever have read-only access since upgrading both to Leopard. Never had this problem in Tiger. Can't even access the drive or folder permissions on the MacBook drive as they're grey'd out (i.e., can't even login to that drive with the MacBook admin account's username/password). Clearly there is a "feature" here I'm not working with properly. Any ideas?

Am going to guess on this one but it may be worth a try... Do you have different 'root' admin accounts on both machines? If so, add the iMac's admin account to the macbook's "allow acess for:" in system preferences/sharing... and no, you do not need to be sharing anything it can be disabled... Good luck.

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.

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 .

Macbook Pro won't mount during target disk mode

I don't know what to do.
I was using Safari today when the whole computer froze. Nothing was responding, so I had to force shut down.
When I went to restart, I got a gray screen with the apple logo and a progress bar; the bar will take a while to fill, then the computer shut down completely. Happens every time now.
I tried booting in safemode and it didn't work; the command prompt details said "Incorrect number of thread records. (4, 29503)" and "Incorrect number of extended attributes (It should be 381007 instead of 381008)"....... What does that mean????
I tried booting the backup drive and running disk utility to diagnose the problem, and it said the disk is unable to be repaired etc.
Now I'm trying to salvage my important files by using the firewire target disk mode with another mac. My macbook pro won't even mount; disk utility said it can't be mounted and is damaged.
Please help--what do I do to save these files???

My workflow was like this:
Partitioned fresh hard drive into 2 partitions: 1 for OS clone, 1 for data recovery
Used Carbon Copy Cloner (an excellent tool) to clone working OS to 1st partition
Attached harddrive to malfunctioning MBA
Held Option on malfunctioning MBA and booted to cloned drive
Once booted, I used old-school Data Rescue II to salvage data from MBA internal drive to my data recovery partition. (Probably need a newer / better data recovery program, as this one changed file names, moved things around, was generally not that awesome...)
Used Disk Util from booted clone to format MBA internal drive.
Used Carbon Copy Cloner to clone to formatted MBA internal drive.
Shut down, disconnected external drive, MBA booted normally.
Think that's everything. I've been touting the excellence of Carbon Copy Cloner for a while now for backups. In my opinion it's much more thorough than Time Machine backups, as you don't need a functioning OS. You can boot to a clone -- time / life saving!

Can Target Disk Mode be run from an external hard drive?

Hi
My hard drive crashed on me the other day (again) and the apple genius told me all I could do was recover my data and send it in (again)
QUESTION:
Can target disk mode could be run using an external hard drive as opposed to another mac? If so, how?
I think corrupt files on my external hard drive might have crashed my ibook hard drive and I'm wondering if I should really try using the external to save all my info from my ibook. Am I completely clueless about computers or is this actually a possible problem?
Thanks

HI Andrea,
No, you are not completely clueless. If you follow John's sound advice using Target Disk Mode from another Mac, maybe you have a friend or relative who has one. Here's the information on how to use Target Disk Mode that I found in the Apple Help menu:
Transferring files between two computers using FireWire:
You can use FireWire to connect your computer to another Mac and have one of the computers appear as an external hard disk on the other computer. This is sometimes called Target Disk Mode.
To transfer files using FireWire:
Shut down the first computer and leave the second computer on.
Connect the two computers using a 6-pin to 6-pin FireWire cable. (If both computers have higher-speed FireWire 800 ports in addition to the standard FireWire 400 ports, you can use a 9-pin to 9-pin cable with the FireWire 800 ports to transfer data at higher speeds.)
Open System Preferences, click the Startup Disk, and click Target Disk Mode. (Or, start up the first computer while holding down the T key.)
A disk icon for the first computer appears on the desktop on the second computer. Drag files to and from the disk to transfer them.
When you finish, eject the first computer's disk by dragging its icon to the Trash. (While you drag, the Trash icon changes to an Eject icon.)
Push the power button on the first computer to shut it down and disconnect the FireWire cable.
If the computer to which you connect your computer is running Mac OS 9, it must have FireWire version 2.3.3 or later installed. Use Apple System Profiler (located in /Applications/Utilities) to check the version of FireWire installed. If it has an older version, get an update at the Apple FireWire website at www.apple.com/firewire.
It's a very simple process but it can only be done between two Macs. You can only "target" another Mac, not an external drive.
It sounds like your iBook needs service. And if you think that your external drive caused the problem to start with, I wouldn't use it again if you can do the TDM instead to retrieve your important data.
Also, be careful with total free drive space. Never fall below 15% free space. Open Disk Utility from the Applications/Utilities folder. Then select MacintoshHD in the panel on the left. Then look down towards the bottom of the window on the right. You'll see "Capacity" and "Availablity". It's a good idea to keep track of free space all the time. You need a minimum of 15% just to boot.
Hope this helps...
Carolyn

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.

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;

Can I access files copied to this machine in target disk mode from this machine?

Can I access files copied to this machine in target disk mode from this machine?

HI Claire,
YOu didn't indicate which Mac OS you are using so I'm going to assume 10.4.x.
Connect the FireWire cable to the target computer after starting it up in FireWire Target Disk Mode.
*If the cable was already connected, unplugging it from either computer and plugging it back in should allow the target computer's hard disk to appear on the host.*
Also, make sure you have the most recent Firmware for your iBook... go here:

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,
-Alec Page

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.

Check if Someone used Target Disk Mode on my comp?

Is there any way to see if someone "hacked" into my computer using Target Disk Mode? My only thought is to check the Console but I see nothing active during the time frame I was thinking it happened. Also, can someone delete that info from the Console if they wanted?
Thanks for any info.

hawkeyext wrote:
Just tried what you suggested and no, unfortunately the Console does not log that data down. I'm surprised there is no way to find this information out. Does the hard disk have any sort of log for when it's powered on? I know the Apple Geniuses at the store have access to this because they can test out the battery. I've seen them pull up charts with Charging Times and more.
The hard disk will write changes using the date & time set on the device writing to it. In the same way as any other external disk.
You don't seem to have fully grasped that Target disk mode (TDM) is the Mac's firmware turning the Mac into a 'dumb disk drive'. The Mac OS installed on that hard drive is not in control of the OS - otherwise TDM would be useless for restoring a damaged OS. You can use TDM when the HD is blank etc because the installed OS it is not in control.
Permissions still prevent users reading & writing things they don't own, but anyone with experience will be able to disable/ work around that.
BobHarris is right about physical access. Encryption is the only way to go, combined with a lot of powering down when not in use.

My account, my files, but can't see them in Target Disk mode?

I have a desktop machine and a laptop (PowerMac G5, Intel MacBook) both running 10.4.11. When the laptop is connected to the desktop in Target Disk mode, I can't see my laptop user account's desktop files, or files in the Document and other folders. I make clone backups of the laptop onto an external drive using SuperDuper, and have this problem in that environment as well. I understand that this is about account permissions etc. but how can I get access to an (admin) account that I myself manage?
SuperDuper tells me that it is because the short names for the accounts are different. Should I take the drastic step of using the utility ChangeShortName to change one of the names? Or is there a more ordinary fix?
Thank you--
Hester

Thank you Niel, for your suggestion.
However, it does not seem to do the trick. I did allow "All others" full read/write access to the account's Desktop, Documents, and other folders, but when I restarted the laptop in Target Disk Mode, the red minus signs are still there and I still get the message telling me I do not have sufficient access privileges. I am able to see the files in the account on the laptop that has the same short name as the account I'm using on the desktop, which is why I asked about changing the short name.
I am the administrator of both computers but have different account names for the primary accounts I use on each. This is a problem to me in Tiger. I used to be able to transfer files easily from the laptop when it was in Target Disk Mode.

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?

Power Mac G4 stuck in Target Disk Mode

The other night I put my Gigbit Ethernet into Target Disk Mode so I could migrate my files to a newer machine (a mirrored drive door G4 with dual 1.42mhz processors). After the migration was complete (which took 9 hours), I tried ejecting the target disk but got a perpetual spinning beach ball and had to force everything off. Unfortunately, either because my newer machine came with a faulty Tiger installation, or my migration messed the installation up - the finder kept crashing and things such as "Get Info" wasn't working- I had to endeavor to get a working version of Tiger on the newer machine. I wanted to clone my older drive to my newer drive.
Futzing around for over an hour to try to gain access to my old Power Mac's hard Disc, which was still, according to the bouncing Icon on the screen, in target disk mode, I could not access the drive at all from the newer machine. When I tried, such as by double clicking on its desktop icon, by right clicking on the same Icon, or if I went into the system preferences to change the startup disk with the gigabit ethernet attached, I got the perpetual spinning beach ball. Also, I could not access the drive from the disk utility app that is on the Tiger install DVD. Luckily, I had a pretty fresh bootable backup of the gigabit ethernet on a firewire drive that I cloned to my newer computer. I just have a handful of files that I want to transfer from the gigabit ethernet if I had my drothers.
Am I screwed here? Is there a way to force my Gigabit Ethernet out of Target Disk Mode without hooking it up to another computer? If it's possible to get the Gigabit Ethernet to boot again successfully, I can transfer my file over my network. Any help would be appreciated.
Cheers

I am confused...it sounds to me like what you wish to do is to make an exact copy of the hard disk in your Gigabit Ethernet and apply that copy to the drive in your MDD, correct?
From what I understand, you are saying you cannot access your GE's hard disk using target disk mode? Or am I mistaken? Also, can you not boot up normally on the GE's hard disk? Is there something wrong with it?
The easiest way to clone a disk is to just make a disk image of the hard disk you wish to keep, and then apply that disk image to the destination disk. Disk utility can perform all this very easily, and pretty quickly. Of course, if you are having trouble booting in target disk mode, this can be a problem...
I'm still kind of confused on what exactly is the problem, and what you are trying to accomplish. Could you please explain a little more and answer the questions above? Much appreciated.

Using Target Disk mode to reinstall OS-X

I have a PPC G5 Dual 2.0gHz which failed the other day. All the fans were running full and a red LED showing on the logic board (it's just a warning I think). Since then the machine cannot be started up. It will begin the startup process normally but will hang on the Apple logo screen (no spinning gear wheel).
The same thing happens when attempting to start up from the install disks and also when started in safe mode or with Option pressed down at startup.
The logical assumption (given the original failure) is a hardware problem but I'm not entirely certain that's the case and cannot get it to a technician right now. I can run Apple Hardware Test and it passes that. I can also mount the G5's drive in Target Disk mode using a PowerBook G4 as a host so the drive itself appears to be okay. All the data is there and can be transferred.
Is it possible that this is software not a hardware issue? The normal startup chime is there, the relay clicks at startup and it does begin to access the drive and all the normal noises can be heard. Just stops loading at the Apple logo screen. I'm wondering if some OS files were corrupted in the original crash (which happened overnight so I don't know what caused it) and if there is some way to eliminate the OS as the problem before going to a technician.
As I can mount the drive in target mode, is it possible to use my PB as a host and reinstall the G5 OS-X that way? They're different machines so I don't know if that would work or the PB would reject the installation. Alternatively, if it could be just corrupted OS system files would it make sense to try to 'guess' the most likely to have been corrupted and manually replace them, again using the PB as a target host?
I'm really stuck without this machine but just can't get it to a workshop for at least a couple of weeks so I'll try anything!

Boy, I love these forums, and I love Macs (most of the time). I was so convinced this was hardware but it seems (fingers crossed) to be fixed. Yay!
You guys were both right in a way. Roam's solution would clearly have been the easiest but because I had tried it before without success I didn't expect it to work. And, trying it again with the G5 install disk, it didn't. Same problem as before. But Graham's reminder of using the original multi-machine Tiger disks in target mode made me wonder. So before trying Target Disk mode I tried just restarting the machine using the Tiger DVD instead of the G5 disks -- and it booted into the installation dialogue!
I figured I'd need to reinstall 10.4 (and, if it worked, go through the whole update drag to get back to 10.4.10). Before I did that though, on a whim, I tried quitting the installer and selecting the normal G5 system as the startup disk. Restarted and voila -- there it was, all back to normal, everything sweet and no data lost!
I didn't even need to repair the disk. Disk verify shows no problems. Even repairing permissions was just a couple of minor changes. I'm amazed. And delighted.
I might be jumping the gun and there might still be a hardware problem that will repeat the original failure and I'll find all the fans going full blast and nothing working again tomorrow but, if Murphy is having time off, for the moment I'm back in business.
I would love to figure out what caused the problem in the first place. I suspect a big power surge overnight did it but I have no idea exactly what it did to cause these symptoms.
My grateful thanks guys.
