filesystem programs

[Dan Bethe <dtm@netcomi.com>]

Hey there.  I'd like to have a program for my //gs that can perhaps do
more reliable file copies than Finder does.  Perhaps in the case of a
damaged floppy.  Are there any freely distributable filesystem recovery
programs?
	Back in the day when I had a //gs full time rather than this used hobby
toy i just picked up, I had some character mode program I used to copy
damaged disks to my RAM disk, then format the disk, then copy back.  The
disk worked again.  I was irrationally frugal with floppies back then. 
But it always worked.  Even if i had to do it repeatedly on a known bad
disk.  I forgot what it was called; it might have been Copy II Plus or
something like that.
