Having trouble seeing contents of RAID-0 drive

[gigabz666]

At the moment, I have three hard drives. Two 250GB in RAID-0 configuration with Windows Vista on it and one 1 500GB with Kubuntu Gutsy. The linux drive also holds GRUB and I was able to boot into Windows by adding it to /boot/grub/menu.lst using (hd1,0).

I noticed that in the storage media folder the RAID-0 drive showed up as a full 500GB, whereas in something like gparted, they would show up as separate drives and I wasn't able to do anything to them. (They would state unallocated). If I went into the folder for the RAID-0 drive, at the bottom of Dolphin, I got hal-storage-fixed-mount-all-options refused uid 1000.

Anyway, a quick little search and I thought maybe I should install dmraid. I tried to access the RAID-0 drive again in Dolphin and now I have
Error opening partition device: Permission denied
Failed to mount '/dev/sdb1': Permission denied.

Here is my output for sudo fdisk -l

I've noticed a few times that people are given a link to the Ubuntu website concerning fakeraid. I'm not really sure how to follow it since that seems to be more about trying to install Linux on the RAID drive, but that's not what I want. I have lots of music and videos on the RAID drive that I would like to access and at the moment, the only way I can think of doing it is using an external hard drive.
