I have the same problem "tetley" is having. I installed the current beta version (as of 4/07) without any problems. But when I run Recuva only my C: drive shows, and when I push the Scan button the scan flashes by in a second leaving the results window blank. I deliberately deleted a couple of test files and followed with an immediate scan; they weren't detected. Nothing was detected.
Does anybody have an answer to this problem? (Besides the obvious: "Dump the program!")
Thanks, Reddog
