Thanks, Sam
In case you aren't familiar with FDISK (else I have no suggestions):
FDISK (and PMFDISK) shows only the partitions off a single physical
drive at a time. Look at the top line of the FDISK screen and you may
see "disk 1 2 3" etc.
As I recall, you use the TAB key to toggle between the drive selection
line and the partition selection area of the screen. When at the drive
selection area, use the arrow keys to select the physical drive.
Good luck.
