Mac Data Recovery Guru can help you recover lost data. The application’s interface resembles those of many other similar tools, as it takes the form of a wizard. All you need to do is pick the desired volume, drive or folder and let the app do the rest. Depending on the amount of data to scan, you get the results after some time, which appear classified according to their file types. It is very convenient that you can even preview the contents of some of the files before actually recovering them.
The tool has several advantages that make it a good choice. For instance, there is no danger of rewriting the original files as the tool works in read-only mode. Great news is it can discover hard drives not listed in Finder. In this respect, the tool will still work if there are multiple bad sectors. Likewise, it is good that the tool supports scanning and recovering data from external devices. As to its disadvantages, I really regret that the application does not let you search for a specific file type, which could save some time.
All in all, Mac Data Recovery Guru seems to solve the problem of recovering files that have been lost for several reasons, like disk failures and even accidental deletion. Unfortunately, although the product can be tried at no cost, its trial version does not actually allow recovering any data.
