But many of you may also wonder how those data recovery software actually work, right? Don't worry.

So how does a Mac data recovery work? Let's figure it out now.
1. First of all, the data recovery software will perform a deep scan of your Mac's hard drive, looking for files that are still subject to data recovery. Macintosh undelete tools can usually recover files from external hard drives and USB flash drives as well.

2. After the scan is finished, you'll see a report of all recoverable files. Yes - you can see not only the lost files you need, but also all files that can be recovered on your Mac. Therefore you'll have to filter the scan results. Some apps make it possible to preview contents of the found files, so you can make sure whether it's exactly the file you've been looking for.

3. Finally your lost or deleted files are back together again. It's time to start the process of data rescue. Data recovery tools pick up tiny pieces of data from all over the hard drive and return them to the original state.
