>Description:
Attached a Y-E DATA USB Floppy Drive to a NetBSD box, drive contains
an MSDOS formatted floppy. Floppy attaches as sd0 (but only since
Charles fixed the umass driver :).
'disklabel sd0' reports the following:
# /dev/rsd0d:

8 partitions:

disklabel: boot block size 0
disklabel: super block size 0
disklabel: partition e: offset past end of unit
disklabel: partition e: partition extends past end of unit
disklabel: partition f: offset past end of unit
disklabel: partition f: partition extends past end of unit
disklabel: partition g: offset past end of unit
disklabel: partition g: partition extends past end of unit
disklabel: partition h: offset past end of unit

Floppy and disklabel works fine in fdc floppy drive.
