Why "-y"? It seems to be the default when I do "cryptsetup luksFormat"

That's an older PATA drive:

Have you run the Seagate SeaTools Diagostics? I prefer the DOS version
-- it's a stand-alone bootable CD:
If SeaTools finds a problem:
1. Plug the drive into a different machine and try again.
2. If the problem persists, open up the USB case, pull the drive, put
it into a desktop/ server machine with a PATA interface, and run
Otherwise, it's something in Ubuntu. Try another Linux distribution.
