Hard drive diagnostic

My one year old WD 640 SATA drive has a few bad sectors. Wanted to test
the drive in full so I downloaded the Data Lifeguard Diagnostic for DOS
(CD) Version 5.04f

Booting to the disk it reports "error status code 0120", drive not
found. Funny but I'm using it now.

Does this actual imply a fault in the drive so that it can't report? Or
just a weakness in the WD software not being able to navigate thru the
sata controller?

Have you tried changing modes in the BIOS ? Maybe it is an AHCI
versus non-AHCI issue.

Thanks. Your hunch was 100% accurate.
