We have been trying to use 2 SATA drives with the A7N8X Deluxe Version 2.0 motherboard. The SATA drives are both 80 Gig Maxtor drives. We have been having a lot of problems with keeping both drives recognized. We are not using the the drives in the RAID configuration. I finally called Maxtor. They say that their SATA drives are NOT compatible with the Nvidia chipset controller on the Asus motherboard. The Silicon Image SATA controller may work fine, but it has to talk to the Nvidia chipset at some point. You may want to use a different motherboard without the Nvidia chipset.
