Not a waste of money

I have made that assumption as the reviewer below and even shot an email to CleverFiles with my dissapointement. The truth is DisK Drill works and seems to do a great job. One pointer though, after you download the program go to their website and download and install a patch.
Apparently the problem lays with the App Store and not the Disk Drill.
After accidentally formatting a drive with all my music on it (all Wave and AIFF files) I got most (if not all) of the 2T back.

Thank you.
