I think you have that backwards…RAID 1 is mirroring and RAID 0 is striping no redundancy.
I have already posted instructions on this site that worked for me..but here they go again because I know i sure was happy to recover my data:
My drives were configured as RAID 1 (mirror) so I was able to connect one of my drives to my computer and boot with a Linux Live CD (I used Ubuntu). Once booted you should be able to mount the RAID (4th) partition using command "mount -t ext3 /dev/sdb4 /mnt" sdb may not be the same on your machine..so whatever the partition is..use that
Also…If you use the Ubuntu Live CD simply change to superuser by typing in the command "su" it will prompt you for a password..if you don't know the password change it by typing "passwd su"
Once you are superuser then you should be able to access all your folders.
