Greetings, I got a friend's hard drive with a clean logical volume. The lost data are on the physical volume (USB), but Recuva only checks the logical one. Anyone knows what to do to force the check of all the drive ? I use the free version of Disk Drill and it does just that : 3 file sin the LV, and 215 GB of data "elsewhere". Anyone knows if I can ask Recuva to do the same ? Thanks in advance !
