I've been using the SATA drivers with my MSI motherboard and Promise PDC 20376 controller for some time now. I finally decided, having two identical Seagate Barracuda drives, that I wanted to RAID them and use them as my system drive.
I created a striped array within the controller's BIOS and it says that the array is active and healthy.
When I get into Linux it still has two seperate devices.
lr-xr-xr-x 1 root root 33 Jan 15 07:14 /dev/sda -> scsi/host0/bus0/target0/lun0/disc lr-xr-xr-x 1 root root 33 Jan 15 07:14 /dev/sdb -> scsi/host1/bus0/target0/lun0/disc
Should it not have just /dev/sda now? Or does the driver for this controller not support RAID? I searched the mailing list archives and tried to find something about it in the Documentation but wasn't able to find out either way. If not, are there plans for this? Or is it an issue with Promise IP still?
They are 160 gig drives. I take it they use 512 block sizes.

And if I try to fdisk one it says 160 gigs.
