questions about raid arrays

[Goofy]

I had an raid(can't remember which kind)the controller was nvidia and I decided to remove the raid, because it wasn't doing me any good and it was easier to just backup stuff on a external drive.
Saturday I wanted to setup a dualboot of ubuntu/windows xp home. At first 9.10, but ended up trying 9.04, which didn't work. both are seeing my old raid setup. which is disabled in bios and as far as I know there shouldn't be anything on the drives(reformated already.)

where is that raid info hiding?

just to let you know, all i really want to do is be able to access the files on the windows xp home machine from my windows 7 laptop, but nothing i've found online helps with that. I've tried to network them, but that just adds frustration to no end. microsoft loves to make things overly complicated.

any ideas to these 2 problems?>

I am no expert. Trial & Error was my method.

It appears that your system is still seeing a RAID configuration. I believe BIOS only enables or disables the RAID. It has to be configured in the RAID Controller.

My experience with RAID is you have to break up the RAID configuration in the RAID Controller first before making any changes else where.

I run a RAID0 stripped with 3 x SSD and having encountered a “lost bit” a few times from power outages this last winter. I had to breakup the RAID in the RAID Controller first, and then reformat the drives in a non-RAID configuration before I could reconfigure them back into RAID0, RAID1, RAID5 and or just separate drives.

As I figured this out the hard way I was able to go back into the RAID Controller and break up the RAID configuration and then successfully move forward.
