[comp.sys.apple] funny Prodos access fields

TMPLee@DOCKMASTER.ARPA (11/17/88)

As someone pointed out, Backup II chokes if directories are even
slightly badly formatted.  I have discovered that somehow two (yes, two,
but only two) of the nearly 100 directories I have on my 40Meg hardrive
had somehow had their access field set to $FF.  (resetting it manually
to $C3 with the the ProDos16 exerciser makes backup happy.)  Question --
do any of the Prodos experts have any idea how the fields could have
received those values?  I have not noticed anything wrong in any other
place, although I suppose a few random bytes wrong here or there might
go unnoticed.  (I don't do any block-level I/O and except for a small
program to change the type on some files -- but never used on the two in
question -- I don't even have any binary programs of my own.)
