In trying it on 4 PCs, it only completed successfully on 1 (with only a 30 GB partition). On the other 3, it closed up without warning after scanning for a day or more. Unless you've got a small drive, it's not worth bothering with, and even then there are likely more robust tools. Another strike against it is you can't save or export the results....

It looks pretty nice though. ;-)

Cheers,
