I cannot get my computer out of target disk mode

I had my G4 power Mac (10.4.11) connected in Target Disk Mode to my new Mac Mini (10.7.3) to migrate the file from it to the new Mini. Now I cannot get the old machine to go back into startup disk mode, it is staying in Targer Disk Mode. Any ideas how to bring my G4 back to life?

I followed suggestion and it worked. Zapping the PRAM still has it's uses! I'm cured, thanks guys!

I cannot see all the data in target disk mode

I have an issue where my MacBook pro is not booting into the Yosemite. I see the progress bar hangs at about 45% on the startup screen. I called Apple support and they asked to use the target disk mode to connect to my mac and then copy data like that. I am using the same technique but I am not seeing all the data under users. My data under the folder users had another users data that I cannot see.
How can I see my data for all the other users? Help please!!!

Could be that the the data or directors on the HD are corrupted.
- Copy all data you can
- Try cloning the whole disk to another disk before you attempt recovery methods.
- Try repairing the HD via Disk Utility
- Try a data recovery program

Target computer not appearing on host computer during Firewire Target Disk Mode

My 2009 iMac recently started getting stuck on the white Apple loading screen and disk utility said it has an error that it can't repair. I asked a question on here about this and was told I can back up my iMac files on my Macbook Pro using a Firewire cable.
I bought a 9-pin to 9-pin Firewire cable and have been trying to use Target Disk Mode to connect my two computers but my iMac is not showing up on my Macbook Pro anywhere (desktop, finder).
Here is how I have been told to do this: 1. Connect the two computers with the FW cable. 2. Boot the iMac and hold down T to boot into TDM. 3. Boot up the Macbook Pro and I should see the iMac HD on my Macbook Pro
I have also tried connecting the FW cable after I boot the iMac into TDM (I read somewhere that this works also) and my iMac HD still doesn't show up on my Macbook Pro.
Am I doing something wrong? Please help me with this!
(I wasn't sure which community this issue belongs to so I'm sorry if this is the wrong place for my question!)

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.

Firewire target disk mode install leopard

Does anyone know if it is possible to install Leo via dvd to another computer booted in target disk mode?
My work computer somehow lost some important OS files during an system update, and now I can't get past single user mode, nor can I seem to boot from CD (although I haven't tried in awhile, may not have had a bootable disk at the time). What I want to do is wipe the HDD, and install the OS.

Leopard OS Disks are universal (ppc and intel), so it was irrelevant to include that information.
No it wasn't. I see many posts where people are trying to use installer discs that come with another computer to install the OS on a second model. TDM is a popular way of trying that. Since you did not provide full information in your question as to which discs you had I could not rule this out.
You also don't say anything about the computer models, which would help in answering your questions. The question immediately comes to mind, why don't you just boot from the installer DVD?
Anyway, put the newer computer into TDM with the two connected, you should hopefully be able to see the DVD in the drive on the TDM computer and select it as a startup disk on the older computer. Another way is to hold down the option key while booting, but some computers don't have that capability.

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.

Target Disk Mode = MAX FANS!

I know I'm not the only one with this issues as almost every Mac I've ever used has done this.
Why is it that when you run your Mac in target disk mode, the fans slowly rev up until they hit max speed, and then it just stays that way. EVEN IF THE COMPUTER IS IDLE AND NOT DOING ANYTHING!!!!
I think this is kind dumb. In Target Disk mode, only the hard drive is active. Everything else like the video card, processor, etc is not active as that is what the other computer is for. Only the hard drive is running, so why do the fans need to be maxed when only one component is running when any other time the fans never come on that high unless i'm processing video or doing something intensive like that.
Any ideas?

Because the OS normally controls the fans, using the computer's activity and the processor to calculate the needed speed and send the request. When the computer is in target disk mode, there's nothing to control them, so they do everything they can to ensure the computer doesn't overheat.

Good explanation! Thanks!

While YOU may not have attempted to jailbreak the phone, SOMEONE ELSE did. Error 1015 occurs by attempting to restore a previously jailbroken phone.
It's very likely you may NEVER get your phone out of recovery mode and your phone may be rendered permanently bricked.
Terms of Use of this forum prohibit the discussion of jailbroken phones. You'll have to scour the internet for a solution to your problem, if indeed one exists.

I keep getting an error message that says that the hard drive cannot be repaired. Therefore I cannot get the computer to start up.

It doesn't sound like you are doing anything incorrectly from what I can see. Have you tried restarting the iPad and then see if you can backup?
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

Hallo, I cannot get my computer or i tunes to recognize my iphone. I´ve got a Lenovo and iPhone 5. Thanks for help

With the phone connected to the PC via the USB cable, can you see the phone when you do Start - Devices and Printers on your PC ?
If you can - right click on the phone icon it is showing and go for "troubleshooting"

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.

Migrating Information in Target Disk Mode Wiped out hard drive

I just helped a friend install Leopard on her new MacBook (it came with a drop in disk of Leopard). After the install, I started her previous 3-year old MacBook in target disk mode to migrate over old system settings. During the migration, the new MacBook froze up and forced me to do a hard restart. After restarting the computer, it would no longer recognize the old MacBook that was still in Target Disk Mode.
After awhile I finally decided to pull the hard drive out of the old MacBook and hook it up to my WiebeTech DriveDock. I now get a disk insertion error telling me that the drive is not readable. I have tried DriveGenius, but I cannot rebuild or repair the drive because it doesn't even pop up.
Has anyone heard of the migration assistance wiping out the drive you were attempting to migrate from? And also, does anyone know of a way to fix this?

She backed up with Retrospect a couple weeks ago, so not much would be lost if I wasn't able to resurrect this drive. The feeling of accomplishment from tackling this problem is the only truly important thing that would be lost.

Macbook in target disk mode locks up when trying to transfer files to another computer. Suggestions?

A week ago I installed snow leopard on my girlfriend's macbook without backing anything up. Dumb idea I know. The installation failed multiple times. I ran her computer in target disc mode to try to save what files I could. Now when I try to transfer files it will freeze up at different times. Sometimes I can transfer a huge amount of data like 4GB's and the other times it locks up trying to transfer 4kB's. I'm at my wits end trying to figure this out. I can see the files but can not transfer them.
Any suggestions or past similar past experiences?

Hi Anand,
Have you noticed when you plug the drive in whether its making any sounds? You can put your ear up to the drive on the Macbook. Its located on the right hand front sided of the top case.
Also, check to see if the target disk mode icon is moving after a few minutes. If the firewire icon has stopped moving it usually indicates that theres something seriously wrong (probably mechanical) with the drive.
Id definitely give Disk Warrior a try. Especially if you have a situation where you can hear the drive running or spin up but it doesn't make any sound after that. Hope this helps.
