Can anyone shed some light on what's happening here, specifically, whether it's a hardware problem with the drive, or a driver problem with FreeBSD?

Footwear which tried to make you take steps twenty-one miles long imposed unfortunate groinal strains; they'd got the things off the student just in time, but he'd still had to wear a special device for several months, and he still ate standing up. -- Terry Pratchett, "Interesting Times"
