Which model is it, Patricia?
The "ALS" model or the earlier one from late 2004 to April 2005?
If it is the earlier one what do the capacitors on the motherboard/ midplane look like? Any sign of bulging or leakage? See http://www.flickr.com/photos/23270082@N03/2644122775/ for an example of a leaking one, but a very slightly bulging top on one can be just as bad. http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php provides some more images etc.
THose "invalid leaf" issues can be devilish to get rid of , by the way, so even if DU said the drive was repaired you should run it again to make sure it comes up "clean" on a second reading.
Sorry for the delay in working on this.
I have run the Disk Repair a second and third time. Now the message is "invalid map code". 1 HFS volume repaired. 1 volume could not be repaired.
I suspect at this point the only option is to format and reload. Since the iMac G5 won't boot to a CD either, I will do the format in target mode. Then I hope the computer will boot to a CD once the hard drive is clean.

You will need a stronger utility to repair. The following will do the job:
Highly recommended for *directory damage* repairs.
Drive Genius Multi-functional utility.
You will need to make your own decision on which to purchase. Read up on them on their websites because each does something a little different.
You must use the versions that are compatible w/your OS system & keep the utilities updated to avoid damaging/harming/trashing your system.
OK. The holidays have slowed me down working on this. I have TechTool Pro 4.0, which I ran on it with no changes.
I have now formatted the hard drive thinking that if it was blank, maybe I could boot to an installation CD, but that hasn't changed, either. I'm about to give up on this one. The hard drive has passed tests. Unfortunately I don't have another SATA drive with a Mac OS on it to try booting to. I did try using our SATA drive with XP, just to see if it would recognize anything more than it was, but it didn't. Now I'm wondering if it's possible that the optical drive is bad.
I also wanted to install a generic version of OS X 10.3 on the troublesome hard drive via USB, but wasn't allowed to do that. I was told I couldn't boot to that hard drive (I don't want to boot to it via USB, I only want to install the OS!)
Any other suggestions would be very much appreciated.
