Found 0 files (732 ignored) in 2.52 sec

I recently wiped an external hd and used recuva for the first time to make sure everything was really wiped. It took 2 seconds and said it found over 700 files, but then when it finished, the report at the bottom says Found 0 Files (732 ignored.)

What does this mean? What is it seeing that is giving me the result of 732 files? I want to sell this drive but I'm not going to sell it if the data I erased can be recovered.

If you click on Options - Advanced you can ask Recuva to display system, zero byte and securely deleted files. This will drop your ignored count to zero. The zero and sec deleted files are not shown by default, as it would be pointless recovering them. Rgds.
