It seems the solution is to disable write caching. So far no errors, and
other people confirm this solution.
Anyway Seagate (inofficially) claims it's a driver issue in Linux - from
http://forums.seagate.com/stx/board/message?board.id=ata_drives&thread.id=2390&view=by_date_ascending&page=6
"We already know about the Linux issue, it is indeed a kernel error
causing the problem as it was explained to me by one of our developers."
