Alternatively, are you sure you have identified your hardware correctly?

According to Supermicro here

   <http://www.supermicro.com/products/motherboard/P4/875/P4SCT.cfm>

the P4SCT has an Intel 6300ESB onboard RAID controller, which according to
this page

   
<http://www.gamepc.com/labs/view_content.asp?id=eoyraid&page=2&cookie%5Ftest=1>

is based upon the ICH4, and not Adaptec controller.  And, unless I've
missed it, this controller is not supported.


What does dmesg output say about the drives and controller?
