Fedora Core Sees Non-Existent RAID
 

I am trying to install Fedora Core 6 on a dual boot machine. There was an earlier version of Fedora Core installed on the same hard disk, although the partitions have been changed. When that earlier version was present, the computer had a SATA RAID setup. This crashed totally, and I abandoned the RAID setup, so the machine now has 3 separate HDDs. One is used solely for XP, and was added after the crash: it was never part of a RAID array. The second is the one I want to install Fedora on. The third is used as a backup.

When I start the install process, the anaconda installer appears to detect some residue of the raid array and generates error messages about this setup saying that there are invalid RAID identifiers. Since I have done everything I can to eliminate the RAID arrays, I'm baffled how to proceed. If the installer attempts to set up a raid array the second HDD from that original array, which now has important backup material on it, will be trashed.

How can I approach this setup in a way that will get the installer to see 3 separate HDDs and not some sort of RAID array?

Try booting with linux nodmraid.

That's a possbility and thanks for the tip. But I really want to get rid of the RAID array entries (/dev/mapper/xxxxxxxx) so this does not happen every time I try to install a new distro or update. I have tried several distros and none will install without reproducing this error. There is nothing left in the BIOS - that is set firmly to non-RAID. So where are these array identifiers hiding, because they remain even after I repartition or reformat the HDD?
