Are you recovering them to another disk or trying to write them to the damaged disk? If you had bad sectors, this is a physical problem not a logical ALso you should have attenmpted recovery before formattng, the disk does not need to be seen in Windows with a drive letter to be recoverable, only need to be seen by BIOS and in Disk management as a ddisk - format is irrelevant. If recovery software needs to see a drive letter then it will probably not be effective. Try scanning with the demo version of r-studio and see if it can find any files, by formatting , and changeing the the filesystem, you will have ovwerwritten some data on the disk, the MFT and NTFS metafiles will overwrite some areas, and potentially could overwrite directory entries from the FAT system.
