The "filesystem" isn't really FAT, although file, vfs-type
and even the kernel recognize and mount it:

Comment 3 Richard W.M. Jones 2012-12-17 03:42:41 EST
Matt: This is the second disk in a Windows dynamic disk array.

Is there some way to tell that this isn't really a FAT filesystem,
so we can add that information to the kernel / blkid?
Comment 4 Richard W.M. Jones 2012-12-17 06:33:27 EST
The MBR partition type is 0x42:

Name       Type        VFS   Label  MBR  Size  Parent
/dev/sda1  filesystem  vfat  -      -    2.0G  -
/dev/sda1  partition   -     -      42   2.0G  /dev/sda
/dev/sda   device      -     -      -    2.0G  -

I wonder if the solution would be to avoid these
partitions when we see that partition type?  According
to http://thestarman.pcministry.com/asm/mbr/PartTypes.htm
this type means:

 42 : -- Secure File System,
         Windows 2000/XP (NT 5): Dynamic extended partition
         PTS-DOS 6.70 & BootWizard: Alternative Linux swap and DR-DOS.
