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.
Target Disk Mode:
Manufacturer: AAPL Model: 0x54444D GUID: 0xD93FFFE7B48EE Maximum Speed: Up to 800 Mb/sec Connection Speed: Up to 400 Mb/sec Sub-units: Target Disk Mode Unit: Unit Software Version: 0x10483 Unit Spec ID: 0x609E Firmware Revision: 0x0 Product Revision Level: 0000 Sub-units: Target Disk Mode SBP-LUN:
Any Help, does this mean the disk is so corrupt that it is unrecognizable? I do not have Disk warrior or the correct system restore cd's, or system software install??

Re: Can't locate the dirve in Target Disk Mode
You are going to need a system install disk for this machine if you want to reinstall it. However, if you just want to run diagnostics, any system install disk for MacOSX should do the trick. You just won't be able to run the installer once you boot from the DVD. The first thing I would do is make sure the eBay seller sold this to you in this condition and without the install disc, because if not, you've got an issue with them.
If you don't have an install disc, your cheapest solution is to call Apple and order a replacement disc for your model computer. You will need your serial number, which you can find on the sticker on your computer. Good luck, and let me know if you need more guidance with this.

Hi John Try reinstalling via your macbook pro but this way round.Put the Leopard Disk into the Macbook and then start the Macbook in Target mode.on the iMac start it up and hold down the Option (or Alt) key then wait.after a short while you will be offered the HD in the MacBook and the DVD. Choose the DVD and see what happens. What happens when you do it the other war arounds is that you are installing a startup system for the MacBook onto the HD of the G5 and not the system for the G5. The installer uses the firmware of the motherboard that is running the install to select the correct version. Another issue is that the disk formatting may be wrong. it's unlikely seeing that you used disk utility from the DVD, but it is possible. Let us know how you get on.
I understand your problem to be that at the time you were executing the critical reboot just prior to installing Windows with Boot Camp, you placed the Windows CD into the wrong optical drive. Now your machine is stuck at the gray screen and is not responding to anything and will not boot from the system DVD
I have encountered this problem previously. The solution is to boot from an external drive containing a valid copy of the Mac OS. Although your machine will not boot from a DVD at this point, it WILL boot from an external drive if you hold down the Option key after you hear the startup chime, and select that drive's icon when it appears. Once you have successfully booted, go to System Preferences / Startup Disk to select the Mac partition of your internal drive, and your machine will reboot normally.
This leaves only the question of how you obtain an external drive containing a valid of the Mac OS. Some options are 1) a cloned backup drive, 2) another Macintosh via "Target Disk Mode," or 3) have someone create you such a disk from another machine. On the plus side, this solution involves no loss of your data, which makes it worth pursuing.
Safe mode just requires holding shift down during start up and if it starts up at all this should be possible. Once in safe mode, you should be able to use Disk Utility to Verify disk and Fix Permissions. To Repair disk or with/without safe mode you need to startup with your install disk and on the first screen or after selecting language, use options to select Disk Utility. You really should tell us the MacOS version--10.3.9 10.4.11 10.5.8 or 10.6 are current and tell us your install disk version, too. With safe mode you can use terminal to run fsck to fix the disk, read the man page. Alternatives include starting up in Target Disk Mode (command+t at startup) and using your computer as an external disk for another Mac by Firewire or possibly USB, fixing it using the others software. These methods in descending ease.
A now permanently dark screen would indicate a bigger problem and a trip to an Apple store for an evaluation. Tell us your iMac model--could affect whether you can easily savage your disk data in this case.
There are several reasons why you could be having this problem. You first need to know a little about the various "flavors" of Apple computers and operating systems.
There are two brands of processors: PowerPC (this is what you have) and Intel (what Apple switched to after your model).
There are also different types of system install disks: Specific Version (this is what would have came with the iMac originally and contains only the drivers for that model). Retail Version contains drivers and "Universal" processor code for all of the supported models and both types of processors.
Intel Macs format their drives differently than PowerPC macs. So, if the used drive was formatted for Intel you wouldn't be able to mount it, if the install disk that was used was Specific Model type rather than Retail type when the system was installed on your used disk, you wouldn't be able to mount it either.
The drive you have must be formatted for PowerPC and system installed from either the Specific Version or Retail install disc in order for you to mount it.
Well the flashing question mark means its not finding a bootable device meaning the hard drive has no OS on it. You should be able to put jaguar on it if its a retail version and not one from another mac product. Let me know how this works for you
