Two phillips 0 screws hold down the panel hiding the hard drive from view.

It is a Seagate 40GB model which appears user upgradeable... It's even mounted to a quick-release drive caddy.

Attempting to free the drive from the cage we find the first warranty sticker. All this means is I'm headed in the right direction!

Two annoying screws later and the drive slips free of its hot-swap cage.
