I have a drive that connects with usb (use it for backups).  This is a 
stanard drive in a usb enclosure, and here is the output of my 
fdisk -l:

fdisk -l

Disk /dev/hda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        2611    20972826   83  Linux
/dev/hda2            2612        3917    10490445   82  Linux swap / Solaris
/dev/hda3            3918       24321   163895130   83  Linux

Disk /dev/sda: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1       48641   390708801   83  Linux

Your system sees the drive as /dev/dm-0px, where x is the partition
on the drive.  You also show a /dev/dm-1px.  This really looks like the
disk was setup by some kind of disk manager.  If you are able to run
fdisk on /dev/dm-0 and /dev/dm-1 then you can probably delete the 
partitions and create one big one in each of the virtual drives.  Word
of warning if you do this the drive will most likely not be able to be 
returned.  If you are already at that point, then there is no harm in 
trying.
