My HD has a hole where the jumpers are supposed to be. It has SATA written on it and not SATA 3GB/s.
So I think it's a SATA 1 drive (1.5GB/s already), so no luck with the "downgrade". For the record, it's an hitachi HTS543225L9A00.
Is there a way to get a log in order to analyze where MOS fails when trying to initialize the drive?
