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


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:

Quote:
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:

Quote:
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?

Well, my hunch is that in your initial setup FC10 mapped sdb as being claimed by dmraid (which is logical because you needed it for your raid-0) in an effort to protect you from mounting the raw device /dev/sdbx and destroying your raid. The question is:
Where does fc10 hide that information? I suspect that either you might need to rerun mkinitrd or see if there is a udev rule concerning your sdb drive and dmraid. Sorry, I'm not that familiar with fedora, haven't tried it for a few years. Hope it helps.
