If you're getting a physical read error, I would expect the hard disk
driver to be giving you an error message along with mount's or fsck's
message.  Whenever I've seen a bad sector pop up, the driver gives you
the physical sector number.  But doesn't ISC do dynamic bad sector
mapping?  ESIX does; this is a really nice feature.
