Sorry,
A bit more info. Forgot about fdisk!
Code:
Disk /dev/sdd: 15.9 GB, 15931539456 bytes
1 heads, 32 sectors/track, 972384 cylinders
Units = cylinders of 32 * 512 = 16384 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdd1 257 972384 15554048 c W95 FAT32 (LBA)
Partition 1 does not end on cylinder boundary.
Confirming that it is in fact formatted to fat.
