didn't either!). Well.. I tried fakeraid with the nvidia MCP... Well, it
wrote something on there which dmraid detected... It asked me during the
installation if I wanted to load the "SATA RAID". Of course I said "no". But
the install detected it anyway. So, to remove you have to do "dmraid -rE".
Just something I tried from other forums... Then it told me : Do you want to
remove the tag nvidia blabla bla... That's where I knew that Nvidia RAID was
interfering even after being disabled.

I'm not out of the woods yet. I created my partitions manually on both
drives but the "Configure software RAID" won't bring up my MD RAID1
partition to assign the "/" partition and doesn't show anywhere. I'll try
another reboot for that.
