Is MS-DOS(FAT) the same as FAT32

I am trying to reformat my External HD to FAT32 using Disk utility but this is not an option. Is MS-DOS(FAT) the same as FAT32?

MacBook Pro, Mac OS X (10.7.2)

Hi Connor,


I'm not on Lion, so I cannot test it. MS-DOS(FAT) has at various times stood for FAT16 or FAT32. On my machine, running 10.6, formatting a disk MS-DOS(FAT) using Disk Utility results in FAT16. I can use Terminal to create FAT32.


Unless someone has a definitive answer, why not just format it, then use Get Info on it and it will tell you if it's 16 or 32?
