    Angry [SOLVED] Mounting fakeRAID array with NTFS

    First of all, yes I searched Google and the forums and I haven't found an answer to my question.
    A few hours ago I've installed Ubuntu Karmic on my VAIO VGC-RC210G PC via Wubi. I have Windows Vista on the main (fake) RAID0 array and Ubuntu on another drive (along with my media files).
    dmraid seems to be working, it recognises my Intel fakeraid, but I can't mount it. Console log here:
    Code:
    root@ubuntu:/dev/mapper# dmraid -r
    /dev/sdb: isw, "isw_bjgfjedfji", GROUP, ok, 312581806 sectors, data@ 0
    /dev/sda: isw, "isw_bjgfjedfji", GROUP, ok, 312581806 sectors, data@ 0
    
    root@ubuntu:/dev/mapper# dmraid -ay
    RAID set "isw_bjgfjedfji_Volume 0" already active
    RAID set "isw_bjgfjedfji_Volume 01" was not activated
    
    root@ubuntu:/dev/mapper# dmraid -tay

    root@ubuntu:/dev/mapper# ls -la      #this is /dev/mapper

    root@ubuntu:/dev/mapper# mount -t ntfs /dev/mapper/isw* /media/raid_vol0
    NTFS signature is missing.
    Failed to mount '/dev/mapper/isw_bjgfjedfji_Volume 0': Invalid argument
    The device '/dev/mapper/isw_bjgfjedfji_Volume 0' doesn't seem to have a valid NTFS.
    Maybe the wrong device is used? Or the whole disk instead of a
    partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
    Note the output of "dmraid -ay". How can I activate the second entry? Because I bet that is the problem.
    Also, GParted says I have two volumes on the RAID array: an unallocated thing (probably recovery info used by the BIOS) and the device that was not activated by dmraid (it has a warning sign next to it).
    Might be a noob-ish problem, but please help me! I don't want to go back to Vista again due to poor hardware support!

    Thanks in advance! Andy

    EDIT: Problem solved.

    Doesn't anybody know? I really don't want to be stuck with any DRM-plagued, evil, proprietary and unsecure Microsoft creation.

    Nevermind, I got it working!
    The problem was the RAID array's name "Volume 0" had a space in it. I renamed it to "Volume0" and now Ubuntu automatically detects it and can mount it.
