Kevin,

         ddrescue -v -f /dev/sdb3 /dev/sdc1 /media/(user)/log

Personally I prefer to save the recovered data as 'images' on an existing filesystem, that way it's a bit easier to manipulate them, and you can always load them up via the loopback if you want to fake a physical drive; ie

($pwd is some path where you have enough room to store the image/clone of /dev/sdb3)
        ddrescue -v -f /dev/sdb3 sdb3.img sdb3.log

Hope that helps

Dear All,

I'm attempting to clone a corrutped Windows partition from bad
disk/partition sdb3 to external HD device/partition sdc1

The command I am using is:
ddrescue -v -n /dev/sdb3 /dev/sdc1 /media/(user)/recoverylogfile.txt --force
(doing '-n' at first to skip errors so i can return to them later)
(added '--force' because without it I get the message "output file
exists and is not a regular file". '--force' allows me to overwrite
what is on the target device).

Even if I shorten up the logfile part of the command to just
'logfile.txt' with no path, I get the same error. However, if I omit
the logfile part of the command, the utility runs. However, I need the
logfile to go back and try to recover parts of the drive with errors
later.

Any assistance much appreciated!

Thanks!

Kevin
