From: Excalibur on 17 Dec 2009 21:32 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.

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: http://noname.c64.org/csdb/release/?id=66765 -- http://www.hitmen-console.org http://magicdisk.untergrund.net http://www.pokefinder.org http://ftp.pokefinder.org 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. <Fravia>

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. --------------------------------------------------------------------------- Peter Schepers, | Author of : 64COPY, The C64 EMU file converter Info Systems & Technology | http://www.64copy.com University of Waterloo, | My opinion is not likely that of the Waterloo, Ontario, Canada | University, its employees, or anybody (519) 888-4567 ext 36347 | on this planet.

Too bad! 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.
