Are there any good utilities, either PC based or Commodore based that
could be used to attempt recovering a 3.5" CBM floppy disk. I finally
found my old root partition backup from the mid 90's and there's a
couple of DMBBS files that should be on it that have otherwise been
lost. Problem is, the damn thing won't read. I did manage to do an
import of it into a .d81 file and it made it through it with alot of
effort but what I got was a disk image that would mount but had no
readable files on it. It would display a directory but the top few
files were listed and everything below a few files down were listed as
garbled characters. Any suggestions will be greatly appreciated.

i have never used it with with 1581 images myself, but you could try my
little d64scan utility, it can find "lost" filechains on the disk and
create a new image:

Some of the most brilliant people I have met on the web are expert reverse
engineers, and I am honoured to count among my friends some capable (and
some half-mythical) crackers. In fact reverse engineering is the sine qua
non for fighting back in a world that is getting more and more
anti-democratic and oligarchic, where money counts more than knowledge
(why?) and where citizens exist only in order to consume useless gadgets
and do and believe what they are told to, surely not to think on their own
nor to co-decide how things should be.

You could use 64Copy (DOS based), and try the CheckDisk (alt-f3) function
to scan the disk. Otherwise use alt-F4 to view the sectors (starting with
the directory) and see if the copy from 1581 to D81 was successful.

Thanks for the suggestions guys. I will give those tips a try. Good
news is that I only need a couple of files as I have everything else
so maybe I'll get lucky.
