    Changed Windows RAID LD to IDE, FC10 can't detect

    I used to have Windows XP installed on a RAID 0 volume, and a separate hard drive to store FC10 in its native partition layout (/boot and LVM). The RAID logical drive was detected by FC10 during installation, and I could mount it using ntfs-3g.

    Later, I destroyed the Windows RAID 0 volume, set the controller to native IDE mode, and used the two member disks as individual NTFS volumes. The problem now is that I can't mount them in FC10. Physically, the NTFS volumes are /dev/sda1 and /dev/sdb1. Here's what fdisk -l lists:

    Disk /dev/sda: 160.0 GB, 160040803840 bytes
    255 heads, 63 sectors/track, 19457 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x23de0de1

    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 16708 134206978+ 7 HPFS/NTFS
    /dev/sda2 16709 19457 22081342+ f W95 Ext'd (LBA)
    /dev/sda5 16709 19457 22081311 b W95 FAT32

    Disk /dev/sdb: 160.0 GB, 160040803840 bytes
    255 heads, 63 sectors/track, 19457 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0xb75f8dbe

    Device Boot Start End Blocks Id System
    /dev/sdb1 1 19457 156288321 7 HPFS/NTFS

    Disk /dev/sdc: 40.0 GB, 40019582464 bytes
    255 heads, 63 sectors/track, 4865 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x00030ec5

    Device Boot Start End Blocks Id System
    /dev/sdc1 * 1 25 200781 83 Linux
    /dev/sdc2 26 4865 38877300 8e Linux LVM
    ...where sdc1 and 2 are where FC10 resides.

    When try to mount /dev/sdb1 using ntfs-3g, here's what I get:

    ntfs-3g /dev/sdb1 /mnt/windows
    Error opening '/dev/sdb1': No such device or address
    Failed to mount '/dev/sdb1': No such device or address
    Either the device is missing or it's powered down, or you have
    SoftRAID hardware and must use an activated, different device under
    /dev/mapper/, (e.g. /dev/mapper/nvidia_eahaabcc1) to mount NTFS.
    Please see the 'dmraid' documentation for help.
    What do I do now?

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    I think this shows what the problem may be. Even though you have de-raided the drives, they are still attached to a raid controller, so you need to map the device as per the dmraid docs mentioned. I assume these are IDE and not SATA drives?
    Sometimes, real fast is almost as good as real time.

    Yes, they're SATA drives.

    It seems I need to disable dmraid. Thanks!
