Error $51 is "directory structure damaged"--it's not complaining that a
block is bad, but a bad block could have contributed to the problem (a
carefully-placed failure to write a block could have left your disk in
a weird state).

Anyway, what you want to do is run a disk-repair program, like Mr. Fixit,
on your volume.  The damage is -probably- very minor.
