I am migrating two drives from a machine that had an onboard raid controller to a machine that has none.

However, when I go to install Linux (Fedora9), somehow, the drives are seen as one unit - still holding onto the old name I gave the Raid 1 array.

I've tried formating and installing on them separably, you can see both drives with fdisk when it boots off of one. However, when I try to re-install with both drives connected, the install still sees just one.

What must I do to purge the old mapping(?) information from these disks?

I've come to the conclusion that there is a hidden partition on these drives. I've wiped both now. This is the message that comes up:

The partition table on device mapper/ddf1_<oldarrayname> was unreadable... etc.. must initialize... etc..

I've initialized it before... it doesn't really wipe ALL DATA (as it warns) because the info remains!

Does anyone have any ideas?

Okay. Apparently I need to launch my install with the switch: "linux nomdraid". Of course I'm using the GUI Fedora 9 installer and have no idea how to do that...

So I'm off to the Fedora section.

Thank you.

Had to low-level (zero fill) disks with SeaTools (text version).

Is this typical of Hardware Raid controllers? How horrid. Took two days.
