Dead Hard Drive controller?
I have an iMac that one day booted up to the folder/question mark screen. I decided to try disk warrior which couldn't find the hard drive at all. Of course my first instinct was that the HD was dead so I decided to throw in a known good Hd that I had lying around. Turns out that that hd couldn't be found either. I could tell the Hd was getting power so I tried a known good sata data cable. Still nothing. Also I tried to put it in target disk mode but the fans just started blasting and the screen would stay black. I'm assuming that's what happens when there isn't a disk to be targeted.
Other things I tried was starting from a leopard dvd and using disk utility. No disk appears! An external usb drive showed up though after I plugged it in. I proceeded to try to install leopard to the external drive but it failed part way. Also I wasn't able to boot from the original disk after I pulled it from the machine and put it in an enclosure. It would not even show up as a startup disk! I started to suspect the logic board but a ran the ASD utility disc looped for 7 hours and the machine passed!
Could it be that just the connector for the SATA drive on the logic board is faulty? Anyone else had this problem?
Ist dies eine gute Frage?
