It also works well for USB or flash drives, not just for recovering files on your primary HDD or SSD drive.
The version I reviewed was 18.104.22.168 PRO for Windows.
When you first run the program you have a list of all your drives that it detects that you can start recovery on, or continue where you left off. You also have option to snapshot an image of your disk too.
After you click the Recover button it will start scanning your drive looking for files that it can recover, it will also sort them into categories based on file type like Pictures, Video, Documents, Audio…etc.
Obviously when you purge files the is no way to know what the original file names were, and the dates can be somewhat inaccurate on the file modify date/time stamps, but I generally was able to recover a bunch of recordings that worked fine.
When I searched the audio section I found a lot of mp3 files that I had purged around Christmas time when I found I had so many duplicates in my mp3 collection, so these were all there and recoverable as well.
Bottom line, I found Disk Drill to be very simple, it scans, it finds and shows you want you can recover. Provided your data hasn’t been overwritten most simple delete and empty recycle bin files can be recovered in a short enough time provided the disk hasn’t written over that data section yet. I was hoping a program like Disk Drill would have had other features, like being able to list all active files on a disk showing sizes, to help you recover drive space, or even the ability to purge/overwrite and secure your drive, but it is very single purpose in nature other than offering the backup option.
Though you do have the option called Protect which is the Disk Drill Recovery Vault (read more here) this allows Disk Drill to run a background service to store META information whenever you make changes to the drive, this helps ensure recovery better. Note, Disk Drill is free and doesn’t cost anything to use the software so feel free to give it a try.
