I have installed a new SATA HDD in place of an old IDE drive in this PC.

It is a Western Digital WD3200AAKS (Caviar SE16) 320gb drive.

All the cables are secure (checked many times!)

I've updated the BIOS to A07.

It still can't see the drive in BIOS.

When I go into Drive Configuration and select SATA Primary Drive, it just show "Unknown Device".

Is this drive not compatible with the GX270?

Any help much appreciated.
