    Have an early 20" iMac G5 and the Hard drive started to squeal and then crashed. Tested dive in another iMac and it is definitely bad. Installed new hard drive and the system fails to find it. Formatted it on the other iMac and reinstalled but it still is not seen by the system.

    Everything was running very well until the drive failure.

    Took it to an Apple approved store, paid the $60 to be told that the Mother Board was bad.

    It is hard for me to believe that a disk failure could cause a Mother board failure. Am I missing something here?

    Thanks for any help and advice that you may be able to offer.

    2- 20" iMacs, a 24" iMac, and a new 27" iMac (not yet out of the box.)

    Hard drive failures generally don't cause the motherboard to have problems. Is anything showing up on your Mac when you turn it on? I would try a different hard drive and see if another one works or not. I'm a PC guy (who now owns an iMac) so I'm not sure how tolerable Macs are of off the shelf drives vs Apple installed drives.

    Wait... What is the capacity of this new drive? If it's 1TB or something perhaps the Macs firmware doesn't support that capacity.
