Hmm, do Crays use non-512-byte sector drives? I've never encountered one
before so don't know, but a lot of "esoteric" systems use unusual sector
sizes (eg, AS/400s, various storage arrays, etc - 520 byte sectors are not
uncommon).

Perhaps try booting NetBSD/OpenBSD from CD on your U2 and see if they
identify the drive sector size (they should both say).
