Installation Instructions: Nope, my OEM hd didn't have any papers with it. I just read a book on PC building.
Drivers: Didn't have them. Didn't need them. Plug n' Play.
Mounting stuff: No screws. I used the ones that came with my case.
Interface cables: None with the HD. They came with the Mobo.
Warranty: Little label on the HD that says "warranty void if label removed"
This was a Western Digital hard drive. But it was 80GB. Prolly same stuff though.
