I had nightmares with those Deskstar drives in IBM laptops, so I'll never buy another IBM or Hitachi drive (IBM had a lawsuit, but we had some Hitachis fail as well). Of course, everyone probably says that about the brand of drive once they experience a failure. :)
A similarly-priced solution would be a Seagate external. Bonus that it's powered over USB, so no extra AC adapter needed:
