Major TAR issues

[Dragon]

a friend of mine just DLed a 1.39 gig file - some of you likely know what it is - and its Tar. ok. i extracted it for him into 100 smaller Rar files and scanned them, reporting all perfect. however, when i try to extract them, i get bad block errors. i feel i gotta be doin somethin wrong. any body else know what im talking about or how to fix it?he said its from IRC.

on seperate note - anybody here played hl2 yet?
