Hi, wonder if anyone can shed some light on a problem.
I have a g5 iMac 2.0Ghz. The factory fitted hard disk failed recently and I replaced it with a 320Gb SATA Hitachi drive which worked fine. A couple of days ago the machine frooze while I was transferring a large amount of files from my PC (via ethernet). It remained on the spinning wheel with no data transfer (I thought it was my fault as I had switched my xbox on which had fixed ip temporarily causing the Mac to loose its IP (same as the 360 one)).
I rebooted but the machine failed to find the startup volume (flashing question mark folder icon). I ran the 10.3 setup disk on the machine and opened disk utility but it failed to find the volume. I then ran Apple Service Diagnostics (v2.5.8) which passed all diagnostics (with the exclusion of not listing the hard disk).
I removed the hard drive, fitted it into my PC and formatted it fine (and ran a surface scan to verify everything is ok). I then copied a couple of gigs of data to the drive to verify everything is ok.
After refitting the drive into the iMac I still had the same error (I have also run disk utility again (from both a 10.3 restore cd and the 10.5 upgrade disk from my macbook pro) and the apple service diagnostics with the same results). I have tried resetting the Pram but no difference
On all occasions it sounds as if the drive is powering up as I can hear it constantly spinning (even when sleeping).
Any ideas?? What is the chances this the SATA controller on the motherboard (everything else in the mac seems fine) or is there anything I have missed?
Thanks for any help anyone can give
