Hmmm... Maybe I was too short on explanation. The best practice is "NOT TO MOUNT AT ALL". If your desktop system auto mount disk, just run like: $ sudo mount ... check output to see if device is automounted: $ sudo umount /dev/sdc1 (or what ever disk partition mounted) (It is better not to face this situation but this tends to happen unintentionally.) Use "dd" to make disk image. For that you do not need to mount drive. From root with /dev/sdc being bad drive and /dev/sdd being good bigger drive, do this first. root # dd if=/dev/sdc of=/dev/sdd This is the best way to get a safe copy to work with the testdisk command on the copy. This way, recovered data is safe too.
