back when I was using 5.0.3 I noticed some bad files (gif files usually)
and occasional block overwriting -- I went back to 5.0.2, kept my HD
partitions locked as often as possible, etc. When 5.0.4 came out, I maintained
the locked partitions policy (unlocking only to do maintenance in finder or
Orca). Recently, the $51 errors have been popping up again -- in my GIF
directories again. (I had some sound files die also but there was maybe one or
two.)

Why the hell is error $51 so bad-ass nasty that the ProDOS FST won't let you do
jack (i.e. FILETYPE with a wildcard in Orca or even rename a specific file
in the finder) ??

On a related note, are there any cheap/free Prodos disk recoverers that can
handle hard drive size (i.e. 32 Meg) volumes?
