Your recovered photos open
Most tools do not know where a carved file ends, so they save the largest possible size: a 20 KB photo written out as 500 MB of surrounding disk. The length is wrong, so nothing opens it. Sherlock Forensics Recover reads the true length from the file itself. On one test drive a photo other methods reported as 524 MB was measured at 24 KB.
It tells you when your data is gone
On most modern SSDs, deleting a file makes the drive erase it within seconds. No software can bring that back. Sherlock Forensics Recover says so before you spend hours scanning, rather than selling you a scan it already knows will come back empty.
RAID that measures instead of guessing
Consumer tools ignore RAID. Professional tools ask you to pick the level, stripe size, disk order and parity rotation from dropdowns. A wrong guess produces an array that looks perfect for the first few files and is garbage after them. Sherlock Forensics Recover reads the array's own metadata first. When that is gone it searches the settings and scores each candidate against the file system structures that must appear at computed offsets. It refuses to assemble an array from an out-of-sync disk rather than producing one that mounts and is wrong.
Nothing is written to the drive you are rescuing
Not a temporary file, not a log, not an index. And it will not let you save recovered files back onto the drive you are rescuing, which is the single most common way people destroy the files they were trying to save.
