I have to admit that I only had a short look at this thread so far, so I might have missed something. However, if your (primary) NTFS partition is the active partition, DOS will not be able to see any primary FAT partitions on this drive, not with OpenDOS, not with DR-DOS, not with MS-DOS/PC DOS. You should, however, be able to see FAT partitions as logical drives in an extended partition. DR-DOS FDISK allows to create them even if you don't have a primary FAT partition.

AFAIK this is a restriction with older versions of MS-DOS/PC DOS, but not with DR-DOS. Please let us know if it helps...
