Kubuntu 8.04 and dmraid

I've gotten as far as getting dmraid up and running. Here is the array information:

dpich@dpich-LINK:/dev$ sudo fdisk -l "/dev/mapper/nvidia_fjcbehbb"

WARNING: GPT (GUID Partition Table) detected on '/dev/mapper/nvidia_fjcbehbb'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/mapper/nvidia_fjcbehbb: 1500.3 GB, 1500312633344 bytes
255 heads, 63 sectors/track, 182402 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Device Boot Start End Blocks Id System
/dev/mapper/nvidia_fjcbehbb1 1 182402 1465144064+ 86 NTFS volume set

Anytime I try and mount the array, I get the following:

dpich@dpich-LINK:/dev$ sudo mount -t ntfs-3g "/dev/sdc1" /media/Storage
NTFS signature is missing.
Failed to mount '/dev/sdc1': Invalid argument
The device '/dev/sdc1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
dpich@dpich-LINK:$ sudo dmraid -s
ERROR: ddf1: both header signatures bad on /dev/sdd
ERROR: isw device for volume "Volume0" broken on /dev/sdd in RAID set "isw_cfjajiheid_Volume0"

I've been reading all kinds of forums, and I cannot find any good answer for this.

Any suggestions?

I seem to have caught this thread in the middle. You seem to have a RAID array made with the GPT label; are we looking at a dual boot situation? What's going on?
