Greetings Weird one this. A relative of mine was doing a format/reinstall of Windows 7 on a Core 2 Duo based machine and the machine rebooted as it does during installation. When the machine then posted after the reboot the thing hung up on listing the hard drives (1TB Samsung F3). I instantly assumed that the drive was toast. I took the drive out and tested it on two other machines and it seemed fine. It seems that the drive will now work with everything EXCEPT the machine it was originally installed in. When the drive is connected to the original machine you cannot even enter the BIOS. Any way I installed a 250GB SATA drive in to tide him over for a bit and all was well. That is until he formatted it and tried to reinstall Windows. The thing has only merked that drive as well! This drive will also now work on everything except my relatives machine. At the moment he is running on an old IDE drive. Rough specs ASROCK 4CoreDual SATA2 motherboard with latest BIOS Intel CORE 2 Duo E6600 2GB RAM X1950 I have tried clearing the CMOS and all the usual but to no avail. Could this be a SATA controller problem. Cheers Eddie
The fact that both hard drives still work fine in any other machine leads me to think your mobo is the problem.
Doesn't sound like the drives. The chance of two successive drives failing while doing the exact the same thing are so remote that you may as well discount the possibility.
Looks like a new board is needed then. Which means he will have to buy a new graphics card as the one he has is AGP. Unless he settles for onboard.
