Do Not Buy

Currently This does not work as advertised. You will be better off buying their $80 software from the website. This does not work on local drives and some external drives under Mavericks. Didn’t try it on Mountain Lion. Customer service told be that I basically had a trial version which even when it can find a mounted drive, will not let you actually recover the files, it only shows you the deleted files. Hopefully they update this soon. Very disappointed. Luckly I was able to recover my lost photos another way.
