So here is the idea. I realize that to recover data you must know what the file system is to find the files. However I recently had a drive crash that came back as unformatted. All of my data was still there, I quick formatted and ran recuva and restored the data. However quick formatting the drive runs the risk of overwriting a critical file so I propose a way to tell recuva to treat a RAW drive as NTFS, FAT, FAT32 etc.
