    [SOLVED] Access to riad0 C drive

    seemed simple enough but I cant seem to find something appropriate for my case:

    i have 2 drives in raid 0 - C: which houses my windows system
    then i have my backup drive D: which is what i have wubi installed on

    i have access to D: but not C. i cant even seem to find any reminents of C

    my raid was set up prior to installing any OS

    ls -l turns up nothing (likw, nothing...)
    /dev/disk/bylabel only shows my main drive and external drive
    and i dont remember/cant find the commands to list drives etc.

    If it is supported it will show up in /proc/partitions

    Re: Access to riad0 C drive

    i dont see anything in any of the files in that directory... that file itself is blank

    i seem to recall somehow going into superuser mode to view some files last time i played with linux - but that was KDE and a while ago

    but, then again, the properties show the file to be 0kb in size...

    Re: Access to riad0 C drive

    okay, i re-figured it, and this is what i get:

    Code:
    :~$ sudo mount -t ntfs /dev/sda1 /C_Drive
    $MFT has invalid magic.
    Failed to load $MFT: Input/output error
    Failed to mount '/dev/sda1': Input/output error
    NTFS is either inconsistent, or you have hardware faults, or you have a
    SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
    then reboot into Windows TWICE. The usage of the /f parameter is very
    important! If you have SoftRAID/FakeRAID then first you must activate
    it and mount a different device under the /dev/mapper/ directory, (e.g.
    /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
    for the details.
    now, i did just run ckdsk on a windows boot, and rebooted twice, due to kernel panic of trying to kill init.......
    it did find some errors, but no bad sectors and it fixed everything. (but i think the errors were from the hard boot cuase by the crash that lead me to the kernel panic)

    and, i'm also in Raid.. set up with intel raid drivers before the install of windows (so i'm not 100%, but i think that is a real raid)

    i'll run chkdsk again, and reboot twice again
    but if that doesn't fix it, then how to get around the loading dev/mappers stuff for my system to get raid working?

    editkay, ran chkdsk again and had no errors. rebooted twice and got the same error when trying to mount that again. started looking at dmraid.. seems like some tuff crap

    Re: Access to riad0 C drive

    got it

    installed dmraid (apt-get install... method)
    ran dmraid -ay
    oddly this shows each disk as its won raid, kind of confusing.. just labeled them <nameOfDisk>1 2 3...
    then i tried mounting them

    the first one said it was already mounted but then the second did get my c drive mounted correctly

    now hopefully non of this messed with my windows install
