OT: go to snopes.com--to verify that it's not an urban myth... but there's a nasty new virus making the rounds, it has an attachment of "postcard." supposedly, it wipes the C: drive.
always check snopes to eliminate the BS, but this one checks out.
while your at it, get an external drive for $125, that will hold 300GB, connects via bluetooth, and back up your memories, at least.
