Once you run the program you can opt to do a scan of your full drives, of just the sections with free space, or of just certain areas that you specify yourself. Plus you can choose either a quick scan or a full one. Then just wait for it to finish.
In a few minutes (how many depends on the size of the drive), MiniTool Partition Wizard will display all the lost or erased partitions so you can recover them with just a click.
MiniTool Partition Wizard is quite an interesting tool to help users who want to recover something from one of their drives. It's free and it's very effective.
