Dunno if we have SpinRite around here.

No joy - it's a plain SATA drive, the root drive on a server we use for
backups. ext3, and no, I'm not going to change filesystem types.... The
real thing is why does SMART ignore the results of badblocks (for those
who aren't sure, that's invoked when you do fsck -c), and for that matter,
why the drive (Seagate ST3170811AS) doesn't automagically relocate those
