We used to have problem while tried to install Ubuntu on SATA Hard Drives (RAID), some problem happen because of the ubuntu installer didn't recognize properly the Hard Drives, See one of the following questions :

I'm trying to setup a dual boot system with Windows 7 and Ubuntu 11.04. I added a new drive which is identical to the windows 7 is installed on. When I run ubuntu 11.04 on the LiveCD I can see and mount the second drive and edit it in Partition Software (Gparted), so I setup some partition which will be used by Ubuntu 11.04 including swap, then start the installation.
I have an error during installation, i guest this cause 'this live CD' didn't recognize / can't find my HDD (SATA HDD), anyone find any solution ?

Did you ever experienced this ?
Regarding to question above, we find some usefull tips which usually work on the previous ubuntu version, following how to install Ubuntu 11.04 on Sata Hard Drives bellow

You can boot a live session as usually then enter terminal session, to enter terminal session you can press CTRL+ALT+F1 (you can replace F1 with F2, F3 .. F10), then type this command to your terminal
sudo os-prober
You'll probably see a probing error which could be the reason why your drive is not taken in consideration. It's quite likely that your second drive (where Ubuntu 11.04 will be installed) has leftovers of a RAID configuration, you can solve the problem using this command
sudo dmraid -rE
* (-r = raid, -E remove metadata) and confirm the operation.

After finished some action above back to the "GUI" session (press CTRL+ALT+F1). Then start the installation, Ubuntu 11.04 Installer should recognize your hard drive now.
