One costs more than the other . Seriously, cost is the only difference. And as is the case for most if not all OEM software, it must be bought with hardware (of course, many online resellers use very liberal definitions of "hardware" to sell it by packaging it with a $0.05 screw or something).

Sorry.

After all that back and forth nobody offered to send us a copy of the Deskstar SATA drivers. I am stuck with the XP default drivers. You could send them to AusPup@charter.net if you wanted to be a real nice person.
