But how can it recover files that have been overwritten and marked as unrecoverable?
For the most part it can't. Two things occuring here 1) file is listed as unrecoverable if you recover it 99.999999% of the time you will get nothing but junk 2)file is still listed in the Master File Table (MFT)
The Master File Table (MFT) contains metadata about every file, directory, and metafile on an NTFS volume. It includes filenames, locations, size, and permissions. Its structure supports algorithms which minimize disk fragmentation. A directory entry consists of a filename and a "file ID" which is the record number representing the file in the Master File Table. The file ID also contains a reuse count to detect stale references. While this strongly resembles the W_FID of Files-11, other NTFS structures radically differ.
If you really want too you can wipe the MFT with Wipefreespace on ccleaner
ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION
DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF.
Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark)
ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

Well, actually it did recover many files that it had marked as "unrecoverable". It did especially well with jpegs, to my surprise. I subsequently reran Eraser with the cluster tips setting and there much fewer files remaining. No files of user note at all, just some 0 byte files and filkes that were locked by Norton, as I ran it within Windows.
How did you manage to recover files that were unrecoverable???? did you try it with documents like word, or Open Office? please explain.
