oknpv, where does it state in the link that the the model referenced is an FDE.2 drive? I see other sites listing the same model number (ST9160824AS) but it does not name it as an FDE.2 drive.
However this site from Seagate indicates that the above 160gig drive and models ST9120827A (120 gig) and ST90816A(80gig)are the FDE drives.
