What ATA speed does your mobo support ? What ATA speed is your HDD ? If your 
mobo runs at a lower speed than your disk you may need to go to your disk 
manufacturers website and grab a utility that you can use to force your disk 
to run at the lower speed. I know in theory all these ATA standards are 
supposed to be backwards compatible, but my own experiences tell me otherwise.
