The syntax should be something like: # dd if=3D/dev/fd0 of=3Dimage.flp Take a look at dd's manpage. You can usually get dd to copy data off a damaged disk with the following command: # dd if=3D/dev/fd0 of=3Dimage.flp conv=3Dnoerror Note that this won't prevent data loss. It may allow you to recover good blocks off failing media, though. How confident are you about the cable and the drive itself?
