Disk Drill for Mac is a powerful tool that lets you scan your computer or other connected device for lost files and, with the paid version, recover them. While not all files are recoverable, Disk Drill uses a variety of techniques to find or reconstruct files that were lost or accidentally deleted, and is successful in many cases.
Connect and scan: This program works on files that were stored on your computer, but it can also recover items stored on any other device that you can connect to your Mac. This makes the app a lot more useful, and streamlines your file recovery process quite a bit, since it means you can use one program for just about all of your recovery needs.
Multilevel scans: Disk Drill has two types of scans available, depending on how a file was lost and how long it's been since it was deleted. For recently deleted files, the Quick Scan is most effective and can bring back files with their original filenames intact in most cases. The Deep Scan gives you options when more time has elapsed since a file was lost, but it takes longer and can't always reconstruct the original filename.
Previews: Once a scan is completed, the Preview feature lets you see which items that showed up in the scan are actually recoverable in a useable form. That way, you can quickly determine what in the search results is worth retrieving.
Pay for recovery: Unfortunately, the free version of this app can only scan for lost files. If you want to recover them, you'll have to purchase a license for $89.
Disk Drill for Mac features an intuitive interface, quick scanning technology, and a clear Tutorial to provide an overall excellent user experience. You can try out the scanner for free and view previews of the files found to determine whether or not you'd like to invest in a license for the full program.
