is it a 12-bit FAT partition or 16-bit FAT partition?  12-bit FATs can't go
beyond 32MB in size (could be wrong on the 32mb, but it's around that).

try changing the partition type in linux fdisk to 16-bit FAT.  otherwise,
delete the partition with DOS FDISK and recreate it before formatting.

as with anything involving the partition table, it is a good idea to backup
your important data first.  this is especially true if you use MS code (like
DOS' FDISK.EXE) to do it.
