Try to format a Zip floppy disk using the FreeDOS format command. If the Zip disk is unformatted (or formatted for another filesystem than FAT), "format e:" will fail with "Error reading from drive E: DOS area: unknown media type". If the Zip disk is formatted for FAT16, you can read and write on the disk, but "format e:" will fail with "Cannot get access flags (error 05). Aborting. [Error 26]". If you use MS-DOS, you can format it (unformatted or formatted) without any problems using the "format e:" command.
