In the screen shot below, the file system for each drive is highlighted.  Notice that the computer in our example has multiple hard drives.  One of the hard drives has an NTFS and two drives have the FAT 32 file system.  If you have been able to get to the System Information screen on your own computer, write down the file system used by each of your drives.  This should enable you to figure out the file system of your "problem" drive, and you can now choose the appropriate recovery demo and skip the rest of this lesson.
