I have an SATA Raid 0 configuration that previously had a WinXP installation. I installed gentoo fine but now I want my MP3's and school work off of those XP drives. I have used a /etc/raidtab that looks likes this:
Code:

raiddev /dev/md0
        raid-level      0
        nr-raid-disks   2
        chunk-size      16
        device  /dev/sda
        raid-disk       0
        device  /dev/sdb
        raid-disk       1

then I did a mkraid /dev/md0 and all went well. However when I try to mount it I get the following error:
Code:
mount -t ntfs /dev/md0 /mnt/superraid
mount: wrong fs type, bad option, bad superblock on /dev/md0,
       or too many mounted file systems


So I went back and added a line in the /etc/raidtab "persistent-superblock 1" and got the same message. I don't know what a superblock is or how to find it on an ntfs file system!

My first step was to use a hexeditor (among other automated tools, with failure) to examine the the drives. Here is the first few lines of output:
Code:
hexedit /dev/md0

Looks like all is well but I have no idea. My gut tells me I am going about this all wrong. I have an ASUS a8n7x deluxe v2.0 MoBo with a Silicon Image 3112 onboard disk controller. Has anybody accomplished mounting a NTFS SATA RAID 0 in gentoo?
