RE: [sleuthkit-users] Corrupted floppy

[Bradley B <br...@de...>]

When using conv=noerror it will begin writing to the file when it can read
more data, which will prevent offsets from being correct. A solution is
conv=sync,noerror where it will write zeroes when it has an error reading
the disk. I find using sleuthkit and autopsy to recover files on a damaged
filesystem is more successful than using the operating system and trying to
access the data.

when dd'ing a floppy, try using bs=1 and conv=noerror, then mounting the
image under loopback.

Have had sucess recovering some files which suffered the "thesis field
effect" that way where there was physical damage to the disk. Document
probably won't be 100% intact, but the majority of the content was
recoverable.

HTH,
