The above command would place them in the same folder as ddrescue. Ensure you know where they will be stored. (Note, both the target image file and the log file must be stored on a reliable drive and not the bad drive (which you unmounted anyway).

It allows you to interrupt the program at any time as well as run it against the drive multiple times. ddrescue -v -n /dev/disk0s5 MyVolImage.dmg MyVolRescue.log From what I've found so far (updates may follow), the best way to use the tool follows.įirst, using either a Unix command (below) or Disk Utility GUI, unmount the failing partition(s) if they mounted # diskutil unmount disk0s5 If you create a log file (as you should), you can always stop it and restart with new parameters. Indeed, ddrescue is taking an eternity for me but my drive is rather hosed.

Helpful tip: you can do sudo -s by itself to drop you into a root level shell thus you only type sudo once (drop it from commands above). So this can be found via search, you meant HFS+ (Hierarchical File System).

Sudo testdisk
