Hi Laurie, I'd guess that whatever distro you are running doesn't like the GPT partition format, so hasn't created the device file(s) for each partition. I'd go for the simple option of creating a loopback device using the sector size & offsets in the partition table:
# losetup -o 512 -b 512 -f /dev/mapper/ddf1_RAID0
This should make you a new /dev/loop<n> that avoids existing ones (probably your USB boot stick), which you can mount as NTFS or whatever.
If losetup doesn't like having a block device underneath, then more messing with dmsetup should be able to achieve the same (but I've never done that...)
Good luck, Phil. PS: Did you check in /dev/disk/... for those partitions?
