After securely deleting files on my system. I noticed after using an unerase utility (O&O) that the names of deleted files from months past still show. They cannot be recovered but remain there for all to see.
I've used both of these, norton utilities eraser and a few others, but none of them get rid of them completely. They cannot be recovered, but using the O&O recovery tool, it still shows the filenames that where there and the fileoffset. Try it.
