Target disk mode "USB"

Anybody know if you can start a MacBook (13 inch - white plastic) in target disk mode without a Fire Wire port ?
My version only has USB ports and Internet port. I want to start it up in target disk mode to run DIsk Utilities on
the hard drive. Please let me know if you have an suggestions . . thanks !

If you're doing it from another Mac, you can connect by ethernet and use Disk Utility from there; doesn't have to be TGM unless you've got a boot problem on the target Mac.

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.

Fire wire target disk mode work with usb also?

hi all,
does starting up in fire wire target disk mode also work with usb drives?

No, and it requires a Mac with built-in FireWire.

Can I use Target Disk Mode over USB?

When I enable Target Disk Mode on my MacBook Pro, can I connect that via USB to a PC (which doesn't have FireWire) and use the Mac as an external hard drive?
If not, are there any third-party products which would let me do this?

No. I doubt you can use FW mode on a PC anyway.
The cost of USB or FW external drives is so low buy one for the PC. IF it is formatted FAT32 then the mac and PC can both read and write to it.

Using a MB Pro in target disk mode via USB?

Can a MB Pro be used in target disk mode via USB instead of Firewire?
Thanks!

Perhaps because it's called FireWire Target Disk Mode, and is not designed to be implemented via USB.
Keep in mind that sustained data transfer rates with USB are much lower than FireWire (the 480 mbps for USB2 and 400 mbps for FW400 are max rates, not average sustained rate). Also, USB requires the CPU to manage data flow, while FW does not.
FW400 or FW800 are will work, just not USB.

Upgrading Xserve G5 using USB Optical Drive/ Target Disk Mode

Hello Everyone!
I am trying to update my Xserve G5 that is currently running 10.3 (Panther) to 10.5 (Leopard). I have tried multiple methods and cannot seem to get it to work.
I have tried to:
Use a USB Optical Drive - I tried using a USB optical drive because the Xserve G5 has a CD drive not a superdrive. It recognizes the Leopard Installation DVD as it pops up on the desktop. I open the installation and click the restart button, but it restarts again and goes to my desktop as if I just turned on the Mac. I have tried doing this in Safe Mode (Holding down Shift on Start Up) and trying to select it from volumes (Holding down Option on Start Up). These two do not work.   I believe it is because I am using a USB optical drive and that it wont recognize the drive unless you are logged on in the OS. Could this be it?
Use FireWire Target Disk Mode - I also tried to use target disk mode by hooking up my Xserve to my MacBook Pro 2009. Everything work fine. I put the Xserve into target disk mode by holding down T on start up and it goes into target disk mode. It pops up on my MacBook Pro desktop as a FireWire external device (I can access all of my files on the Xserve hard drive). My only problem is that I do not know how to run the installation disk of Leopard off of my MacBook Pro so it installs it on my Xserve.
Any Suggestions or Ideas would be greatly appreciated.
Thank You
- Ryan

So what should I do since reformatting the HDD through disk utlity on the Xserve is not an option
Why not???
Boot th xSeve using alt key from Install Disc in MBP, then...
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
   3. Click the Erase tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, APM Partition.
Quit DU which puts you back to the Installer... Install.

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?

How-To: Install Bundled Apps to another MacBook Pro using Target Disk Mode

Recently, I replaced the dead hard drive on my wife's computer. All the data was previously backed-up so all I needed to do was reinstall the original OS. Oops! Those disks disappeared over two years ago...perfect, right? No poblem, I already had the boxed install DVD for Snow Leopard and installed the core OS. But what about those bundled applications? Aha! That is the marketing coup Apple doesn't really talk much about. You see, you get the entire suite of Apple branded apps with the original install disks but not with a boxed OS install disk. It's just something that you have to find out for yourself...the hard way.
My requirement: restore all the iPhoto data to the reimaged machine running Snow Leopard. But that data has no application that can read it. Solution - Reinstall iPhoto from another source.
So I developed this workaround I hope the rest of you find amusingly simple, wildly helpful
Here's how I restored iPhoto on my wife's computer:
1) Get two Laptops side by side. In our case we both have macbook pro 2008 computers (Wife's and Mine)
2) Power both down and direct connect a firewire 400 cable (or 800 if you have it) between the two
3) Start the Wife's laptop in Target Disk Mode: Press "T" immediately after engagin the power button, hold it down until you see the "fanned" firewire symbol floating across a grey screen - it's quite large, about the size of your hand making a "stop" gesture
4) No start the Mine laptop by pressing the "option" key (two keys to the left of the space bar)
5) You will presented with a pair of hard disks to boot from, choose the Wife's laptop hard drive
5a) you'll notice now that the Mine laptop is booting the OS system files of the Wife's laptop (Her desktop, her preferences, etc...)
6) On the Mine laptop, insert the original Mac OS Install Disk (#1) that came with the Mine laptop (usually any OEM install disk will work, though)
7) Double-click on the DVD icon on the desktop when it mounts and look for a shortcut that reads, "Install Bundled Applications Only"...launch it
8) Now choose install bundled applications but make sure to press the "Customize" button in order to specifically choose which OEM software you want. In our case, just iPhoto
9) Follow the installer prompts all the through to completion and exit (you will be prompted to insert disk #2 along the way).
10) Remove the install disks, power down
11) Power down the Wife's laptop too
12) Disconnect the Firewire cables from both laptops
13) Power up the Wife's laptop normally
14) Launch the FInder and drill down to Applications. Look for iPhoto and launch it
15) iPhoto will either pickup the "iPhoto Library" that was previously restored after reimaging with Snow Leopard or you may be prompted to manually associate a library with iPhoto.
16) Once complete, you'll se all the restored pictures and data from when before the original hard drive crashed. Wife will be pleased and you'll look like a Genius
This is a really handy trick for troubleshooting a lot of install and restore related issues.
Hopefully you'll find other uses for it too.
Good Luck,
TheHighSierras

I think the problem is that you can't install an older OS X version onto a system running a newer OS X version. So I would try the following:
     1. have an external disk or create another partition on an internal drive to use for the Mountain Lion install (you might have to shrink an existing partition to make room for another)
     2. Create an external bootable USB thumb drive with the Mountain Lion OS on it (do a search on the web for this - for example see http://www.macworld.com/article/1167857/how_to_make_a_bootable_mountain_lion_ins tall_drive.html
     3. Reboot Yosemite and then boot from the USB thumb drive by holding down the option key
     4. run the mountain lion installer and install on the new disk/partition you created in step 1 - it will also create another recovery partition from this same part of the disk
Now your Mac system will have both a Mountain Lion install as well as the Yosemite install. You won't be able to use Migration Assistant to move things from Yosemite to Mountain Lion because it will see that you're "going backwards" and won't allow you to.
Have a good backup of everything before starting in case there are problems.
Good luck...

Is it possible to store a back up on external HD by transfering files using Target Disk Mode?

Dear Apple community,
There's absolutely no way that I'm going to be able to fix my MBP without a clean install. I simply cannot log in and get to my desktop screen after upgrading to Mavericks. So I will have to erase everything and perform a clean install. However, before proceeding with this plan, I'll have to back up my files from my MPB since I cannot use my mac normally, I'll have to back up my files using the Target Disk Mode. I've connected my MPB to another MPB in the past, so I know how the process work. But this time around I won't be able to use another MBP but a MB. I have a few doubts regarding the process especially in what concernd adding an external HD to this equation. So please bear with me and see if you can answer my doubts.
So this is the equipment I'll be working with: my MPB, my friends MacBook (2008) and my 1TB external hard drive.
My basic question is: once I connect my MPB in Target Disk Mode to the MB, I'm sure I'd be able to transfer my files to this MB. But let's say that I don't want to leave my files in this MB (after all it's not my computer) and want to send my files straight to an external HD connected to this MB. Is it possible? If positive, I know that the only FireWire port in the MB is a 400 port. That means my MBP will be connect to the MB using the only FireWire port available in the MB. So I believe that my external HD would have to be connected to the MB with the help of an USB cable. I assume that this will make the transferring process a little slower than if I could count solely on FireWire ports. Slowing the process down is not a problem but could this corrupt any of my files during the transferring process or even damage anything? I assume that would never happen after all it's just digital data, but better safe than sorry, right? What do you think?
Another thought that occurred to me is: let's say I connect my MBP to the MB using the FireWire 400. I'd still have an FireWire 800 port available on my MBP. If I connect my external HD to my MBP (yeah, the one that will be in Target Disk Mode) using that FW 800 port, would my MBP allow this external HD to mount as if it was just another folder/drive in my computer? If positive, theoretically I'd be able to transfer files from my MBP to my external HD manually (by dragging files from folder to folders), right?
I really don't want to transfer my files from the MBP to the MB and then from MB to external HD. That would just take time and I really don't know how much available space I'll find on my friend's MB.
Oh, one last question: when transferring files using Target Disk Mode, do all computers involved in this process gotta have the same OS X version installed or it doesn't matter if e.g one is running Snow Leopard and the other Mavericks?
Looking forward to hear back from you, experts.

Can I install FROM a working iMac TO an iMac in Target Disk Mode?

Hi.
I have a distressed iMac - it's in Target Disk Mode (the Firewire logo is on its screen), and it's hooked up to another iMac. I can see and navigate to the distressed Mac's hard drive via the good one. Can I insert the SL install disk on the good mac and install it on the bad one? I've tried the other way...but the distressed iMac stalls out when booting the install disk visa-versa.
The distressed iMac's internal optical drive is dead, and for some reason it WILL NOT recognized an external firewire/usb optical drive.
Thanks.

Sure, the working mac should see the other one as a firewire connected hard drive, nothing more - so long as the working one is an intel, and the target drive is partitioned suitably; 10.6 ought to install no problem.

No FireWire cable for Target Disk Mode

I have an original MacBook1,1 running Snow Leopard 10.6.8. It will not start up, I have tried everything on this Apple web page , Mac OS X: Gray screen appears during startup, besides an erase and reinstall and I don't know what to do. It won't read the Snow Leopard update disk (My other two Macs do). When I restart In Verbose Mode, it always stops right after 'Airport: RSN handshake complete on en1'. When i started my other Mac in Verbose Mode, after 'Airport: RSN handshake complete on en1', it went straight to the login window. I called Apple support and they said that I need to perform an erase and reinstall but first I need to get an install disk for Mac OS X Tiger 10.4. and get some things off using Target Disk Mode. I do not have a FireWire cable and do not want to have to go and buy one. I have an Ethernet cable and a male - male USB cord. The two other Macs that I have are an iMac7,1 running Snow Leopard 10.6.8, and a MacBook6,1 running Mavericks 10.9.4. If you have any solutions for fixing it without the erase, or just a way to get my info off of it, please help.
Thank you in advance!

The USB cable won't be useful in that situation, and the Ethernet one will only help if you have access to a computer running Mac OS X Server. Get a FireWire cable.

Won't go into Target Disk Mode

Help,
I have an iMac that is several years old, OS X v. 10.3.9, has never had any trouble. I recently bought a new MacBook Pro and have been trying to move files over from the iMac, but I cannot get the iMac to boot up in Target Disk Mode.
I reboot, hold the "T" key, etc., and the FireWire symbol comes up, but then it just slowly bounces around the screen while the machine whirs away, and I don't get any further.
Open Firmware Password is not activated; I've run software updates.
Any suggestions would be greatly appreciated.
Thanks

Hi,
A while back I tried what you have and also, the Panther OS G4 would not show up on the Tiger OS G4, although the Panther OS was in Target Disk Mode with the floating icon.
The connection was per instructions, both on line and step-by-step per the Tiger OS, but no disk showed up even after a few hours of wait.
What I found is that my Panther OS G4 Firewire socket was 'mushy' (it moved fairly easy from slight finger pressure on the plug-in end... it was not 'firm' like my USB socket was. So I tried a Firewire external drive I have, that did work before, and it too, did not show-up (although it did start it by being plugged in). Everything I tried with that Firewire socket on the Panther Computer was not there... although these did work on the Tiger Computer.
Since the Firewire is soldered onto the motherboard I have come to the conclusion that one or more of the connections are disconnected... perhaps not the power one, as the external items react to the plug-in, but there is no 'communication' after the fact.
Perhaps this is what has happened on the iMac end for you. And yes, I have used that Firewire plug many many times and not always with TLC in the past, as it is a laptop.
Now I use a Firewire 400 to Firewire 800 (either direction works, depending on what plug works on which item) for what I have and do... as to repair it would be more then a new computer and the Panther computer is an '05 model (but still used daily for what it does).
Maybe you can check how 'solid' your iMac feels when it is plugged in with the Firewire, compare it to other connections... do it gently though, but if it is loose you will know by the 'mushy give' it has.

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...

Using iPod in Target Disk Mode

Hi all. I have a Powerbook G4 and am being asked to fix a friend's iBook G4. I want to connect the PB and iB together via firewire and boot the iB in target disk mode. My question is, could I back up the contents of their hard drive to my iPod hooked up to my PB USB through target disk mode? Any advice would be absolutely crucial. Thanks all.

Follow the instructions in this article, and then drag files from the iBook's hard disk to the iPod in the Finder. This method cannot be used to back up the entire Mac OS X system; copying files in the Finder should be limited to the Applications, Library, and Users folders, and only the Users folder unless there's software on the iBook that would be difficult or impossible to locate again.

Does the MacBook 2015 support target disk mode?

Will the new MacBook support using the only port it has USB-C to thunderbolt for target disk mode booting?
thanks

Not true: You can access Target Disk Mode through Thunderbolt ports.
I don't know enough about USB-C to know whether TDM is possible: certainly TDM isn't possible on USB-A ports. We'll all have to keep reading the reviews once the hardware is released.
