Format External Disk in FAT, NOT FAT32 I have an external device which mounts as an external drive and which I must format in FAT, not FAT32, for use elsewhere. Is there a way to do that from Snow Leopard?
This should do the trick:

In Terminal:

diskutil eraseDisk MS-DOS &lt;newname&gt; &lt;diskID&gt;


where  is the new name for the disk and  is the disk identifier (you can find this by getting the disk info from Finder or Disk Utility, or by typing "diskutil list" into Terminal).
