PowerPC :: IMac G4 Won't Boot Into Target Disk Mode?
May 12, 2010
I just bought an 800 MHz iMac G4 , and whenever I try to boot into target disk mode it shuts itself down. I am connecting to an intel iMac, and the g4 has no OS installed on it (I am trying to install tiger using my dvd install dvd, the one with the black background and grey x which the G4 won't read). Does anyone know what could be causing this issue? I've already tried reseting the PMU and PRAM.
We have some new Intel iMacs and have transferred some information from our previous G4 PM (one MDD and one Quicksilver) to the new iMacs. For some reason the G4's will now not boot up and kernal panic on the gray Apple boot screen. This has happened to all the G4's we have in our office. They are running OSX 10.2.8 and the iMacs are running OSX 10.4.4. We can still mount the drives from the G4's using FireWire Target Disk mode.
I have tried zapping the PRAM etc but they still wont boot. I have also tried running the OSX 10.2 Installer disks to try and reinstall OSX on the G4's but the installer cannot see the drives?
I tried running the disk utility. It finds the hard drive but wont let me verify/repair permissions (the option is grayed out). It will only let me verify/repair the disk, but it finds no errors. The installer cannot find the disk at all.
We have more than one hard drive in the G4's and the target disk mode will only mount the system drive, it doesnt see the others, so we cannot retrieve out information. Whats going on. Never had this problem before.
Anyone have any idea what is wrong. Never had this problem before using the FireWire transfer.
My iMac won't boot up. I think its HDD is dead . Is there a way for me to use target disk mode to boot from my laptop HDD so that I can rescue my iMac HDD?
I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.
I have a bit of a problem: I cant access my Mac because I lost the password. I recently changed my passwords on several macs, including an old PPC PowerMac G5 from ca 2005. I run 10.5.8 on this and it works flawlessly. I need to use this machine for important work.
So this is what I have tried so far:
1) Tested with all known passwords I have used in the past.
2) Tried to boot from a 10.6 install DVD
3) Tried to boot from just C and later Command C
4) Tried a different install DVD 10.4 (I dont have the original 10.5 DVD)
5) Tried to use T and Target Disk Mode from an iMac with Lion. (disconnected all other FW disks etc.)
6) Tried different Firewire cables
7) Tried different Firewire connections.
It starts obediently and show every sign of Mac-Happiness. But I simply can't get the darn thing to boot. I think it normally should have booted using 10.6?
I'm trying to zero the data on an iBook hard drive before selling it. When I connect it to my Powermac via firewire in Target Disk Mode, it shuts down completely about 30 minutes into the proceedure (and yes, the power adapter is connected).
I've got an early '08 MacBook and an iBook G4. The iBook will only work for a few minutes before freezing completely.
I want to use my MB to get info off the iBook, but when I follow the instructions to start the iBook in Taget Disk mode, the MacBook asks if I want to 'initialise' the harddrive. What's that about?
How can I get the data off my iBook (ideally without re-installing the OS)?
I want to copy files from my old PowerBook G4 (12") to my self-built Windows PC. I've connected the PB to my tower's Firewire PCI card, put the PB in target disk mode, and Windows prompts me with the found new hardware wizard. After the wizard finished, I did not see my PB in My Computer. It does not show up in Disk Management, either. It does appear in the Safely Remove Hardware window as "UNKNOWN MODEL AND VENDOR IEEE 1394 SBP2 Device", and in the Device Manager as "SBP2 Compliant IEEE 1394 device". How can I get this to show up so I can backup my old files?
I just attempted to transfer my files from my old powerbook G4 15" to my iMac 20" using Target disk mode. First I tried to use a firewire cable but it didn't work, I think I was using a 400-400 instead of a 800-400. So I used the option to connect to two computers over a shared internet connection using a password. I thought It would automatically transfer my photos and other files but it just transferred these weird extensions for applications and I don't recognize any of it. To make it worse, I tried to open photoshop on my iMac and now its asking for a password! None of the photoshop series would open, it's asking for a serial number. I had photoshop installed before and the guy doesn't live in my state who installed it for me and I don't have any of the original disks. I know Dell does system restore but Macs work differently. I wish I could undo this whole mess, I need photoshop!!
I dont have the original OS disk either, ughh I should have just splurged on a portable hard drive.
G5 iMac model A1058, 1.8/512mb/160gb.Bought this machine used on e-bay with no operating system, powers on fine, flashing folder with question mark= no operating system. Tried to connect to my i-book in target disk mode via fire wire and the hard drive does not mount on the desktop. Can't find it in disk utilities however i get this in system profiler under firewire.
I'm trying to sort out a problem with a mid-2007 iMac. When trying to start it up normally it would get past the Apple screen, then go onto a blue screen with a cursor and stay there.
I made a bootable Snow Leopard USB drive to try and repair the disk / re-install the OS. Plugged in the USB drive, and tried to boot the iMac into startup manager by holding down the option key. But instead of showing the volumes to launch startup manager, it keeps bringing up a grey screen with the Firewire logo on, which I believe is what happens when launching into Target Disk Mode.
I'm traveling at the moment with my MBP 17". Arrived at my friends place who has a base iMac 21.5". Since I prefer to use the slightly larger screen to work off (even though my 17 MBP has more pixel density). So startup the iMac via TDM on my 17 MBP and to my surprise it works! - as my MBP only has leopard 10.5.8. I would have thought these iMacs would not run unless you have SL 10.6 loaded. It worked the 1st time, but crashed (grey vertical shade of death) twice after. On the 4th time it worked again. So that was weird (the inconsistency). Maybe 10.5.8 is NOT meant to be compatible with the new iMac's?
I have my pbook g4 in target disk mode and I am trying to make a superduper backup but I get "Error starting permissions repair for disk1s3 Powerbook-G4-#1: Operation not supported for the Mac OS X version on the targeted disk (-9950)".
Disk utility doesn't have repair permissions enabled. So, I 've only done a repair disk on the target disk which a journaled hfs+.
First thing to say is that the G4 starts fine (remarkably quickly in comparison with the new iMac) and appears to run okay. However, on running the disk utility I’ve found that there is a problem with the hard drive and it won’t verify either the hard drive or repair the permissions. Like many of its kind the optical drive has failed and therefore I can’t use the installation CD to reinstall or anything else. My daughter has been using the G4 for some years but has upgraded to MBP and wants me to take her files and put them on another hard drive and then wipe the G4 clean. At the moment the disk utility will not work at all. So I’ve been attempting to start it up in TDM via FireWire. The G4 starts up okay in TDM (the FireWire symbol appears on the screen) but there is no sign of it on the new iMac. In the light of what I’ve said so far does it seem probable that I will ever be able to get the start-up disk to work? I have connected the two computers via a Wi-Fi network and have been able to see the disc but when I have run the disk utility it has always reverted back to the G4’s own program.
I have a 15" mbp with 10.6 Intel core duo, 4gb ram with a boot camp and ubuntu partition through parallels. The other day I was installing xcode from apple's website, which failed 3 times after downloading saying the package couldn't be expanded. I left my computer for a while and came back where i then had to log in again. it rejected my password numerous time (i'm positive it was correct). when i restarted my computer i got a kernal panic screen when the apple logo came up. it told me to restart the computer which i did. didn't work. i restarted with the osx cd to use the disk utility. when it checked the drive it found a bunch of errors, which i then tried to correct. it went for a couple minutes then told me they couldn't be fixed and i should try to back up my data and reinstall osx. i don't know how to back up my hard drive when i can't log into my account. i've tried to boot in target disk mode and copy some files that way, but the only disk the other computer sees is my windows partition- no mac partition.
i've also tried these, none of these have worked: restarting in safe mode resetting the ram and pram booting with different sticks of ram all result in a kernal panic.
my windows partition still works fine though (as much as i hate to say it) the only things I really care about on my computer are my files from school and my itunes library. is there any way i can get these files off my computer?
Trying to troubleshoot a macbook pro 2.4 ghz with c2d so I start it up in target disk mode connected to my imac. (The current issue I am having are kernel panics on start up asking me to power off and restart). I am trying to see what the console output for the mbp is, but when I choose the mounted disk and go to applications there and run console, I get the console messages of my imac? What am I doing wrong guys?
edit: for the time being I ll just restart it in verbose mode, see what I get from that.
this isnt fully a mac problem but my windows 7 laptop cant see my g5 in target disk mode any ideas how to make it work? i have macdrive installed so even the hfs hd should show up
I need some pictures from my g4 digital audio onto my macbook, so I started the power mac up in target disk mode with the firewire cable attached, and it didn't mount. I have restarted both computers, and still the disks don't show up in disk utility. Could I have a bad cable, or is something else the problem?
I'm purchasing a new MBP and I'd like to migrate my files using target disk mode, rather than Migration Assistant. Are there any good support articles online that outline best procedures for doing this?
Transferring my documents should be pretty simple, but I just want to make sure that when I transfer my iPhoto/iTunes libraries and the like that I'm transferring the right files to reconstruct those libraries, without transferring over any old files that are unnecessary from my previous system.
Is it possible to boot a macbook pro retina using an external usb3 hdd (=hdd of my previous macbook pro), and boot via target disk mode, so I can carbon copy everything to the flash memory of the new macbook ?
In principle it sounds simple, but does anyone know if it can really happen? Can it boot from usb3 in the first place? (it's faster than usb2 and fw800 so I don't see why Apple wouldn't support it).
It's important to find out before I go ahead and buy the new laptop.
I have an iMac G3 that I suspect has a bad hard drive and am trying to recover a few remaining files from it but cannot seem to access the hard drive no matter what I do.
I got a FireWire and am trying to start it up in target mode. It's connected to my MacBook, but when I power it on with the T key down, it starts to boot up for a few seconds but then shuts down to a black screen.
I have a 2010 mac book i'm trying to zero out. But it will not boot to target mode connected t my mac book pro via fire wire 800 ( im using a thunder bolt>firewire 800 adapter)
I thought having a Macbook and a PC and keeping data sync'd between the two would be easy, or so Apple et al would have me believe. So far I've not only found out that their IP over FireWire, the only feasible way to transfer the large amounts of data I have, is seriously lacking (i.e. I haven't been able to get it to work!) but also that when I try to ease my woes by connecting the Macbook as a FireWire drive in Target Disk Mode, it fails to deliver again. The first time I connected my Macbook to my PC over FireWire in Target Disk Mode, it popped up in My Computer no bother. Alright, so the only partition I could access was my XP partition on the Macbook (thank goodness I have that or I'd be right up the creek!), but I suppose it's to be expected, what with OS X and Windows having different file systems ETCETERAH.
So I'll copy all my media files to the XP partition and then copy them to my XP PC from there, I thought. Every following time I've connected in Target Disk Mode, I've received nothing but a 'removable disk' icon in My Computer which, when clicked, asks me to 'insert media'. WTF, Apple?! So not only can I not have my OS X drive show up in Windows on my PC, but now I can't even have the XP drive show up?! I didn't change anything, I didn't do anything differently, I literally just rebooted OS X to copy the files I wanted from the Apple partition to the XP one. Sorry to come across all 'angry like', it's just not the first, second, or third problem I've encountered since 'switching'. For a company who prides itself on how its products 'just work', it's becoming an eye-opening experience. However, I understand it's probably something I've done incorrectly, rather than the fault of Apple or Microsoft. So I ask you, what am I doing wrong?
I'm just curious if it's possible to put my Mac Pro into TDM, connect it to my MacBook Pro, start it up holding option to choose a start-up disk, and use the Mac Pro's HD to boot up. I'd experiment myself, but the Mac Pro is packed at the moment, and I'd like to know if anyone knows for sure that it will or will not work before digging it out.
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.
