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

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:

     http://www.seagate.com/support/downloads/seatools/


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 
SeaTools again.


Otherwise, it's something in Ubuntu.  Try another Linux distribution.
