Please add the possibility to use mounted virtual disks as source, too.

Please add the possibility to use mounted virtual disks as source, too. For recovery, I always create an image of the problematic disk, then I work on that image. This method allows me to try several recovery programs (when they are able to see that mounted image). Unfortunately, your program is not prepaired for this type of safety option, so please, give it the missing part. Thank You.
