Installation is straightforward, and as simple as any other program. On running the program you find that selecting a drive and viewing files is just as simple and intuitive as the Finder. The process is as simple as selecting a physical drive, selecting a volume for recovery, and then searching or scanning for files and then preview or save files found or recovered.
You need a good drive and volume separate from the one you are recovering data from to install the software and save recovered files to--writing to the same drive is unsafe and can destroy data permanently. The software works in read only mode on corrupted drives, and does not attempt to repair or modify the corruption, it just reads directly from the disk to retrieve the data.

If you are not sure if Mac Data Recovery will work or is right for you, you can download and use the demo to see if the files, folders, volume, drive and the data you want can be recovered.
