Replacing BIOS-mounted Promise PDC 20319 RAID 0+1 with RAID 1 on Intel S875WP1LX board

I have an Intel S875WP1LX server board and MS Windows Server 2003. The board has Promise PDC20319 SATA RAID (FastTrak S150TX4) embedded in BIOS without a Promise controller board. Originally, a RAID 0+1 (striping+mirroring) was set up using two identical Seagate ST3160827AS 160GB drives. But one drive died, taking with it all the RAID-based data. I bought an identical replacement ST3160827AS. Now I want to install it, but replace the RAID 0+1 with a RAID 1 (mirroring only), without changing drivers or losing data from the surviving drive. But Intel provides no more tech support for the S875WP1LX board, and Promise Technologies offers no tech support for their products that were sold through the board manufacturer. So how to proceed?

SOURCE: Conflict between Promise Ultra133 and SATA RAID controller

Check that your RAID controller and onboard SATA controller aren't in a compatibility mode. You can put them in this mode while you have no SATA driver installed in Windows.

This tricks Windows into seeing the SATA drives as regular IDE drives. Your BIOS then has a spasm when it see's another IDE controller there, and just uses the card instead.

Make sure the SATA drivers are installed first, otherwise anything SATA will stop showing up. (and your Windows just won't boot if it's on a SATA disk and you take compatibility mode off) =-]

SOURCE: Promise FastTrak TX2300

You will need to download the drivers on to a floppy disk. When loading setup press F6 when it asks if you want to use third-party RAID controller.

You can get the drivers from the below link

SOURCE: I have installed the Intel

The drive labelled Intel MegaSR SCSI Disk Device must be the Raid drive, which would mean it is installed. It probably just needs a Drive Letter assigned to it.

  1. Open the Start Menu, and then click Run.
  2. Type in diskmgmt.msc and then hit enter or OK.
  3. In the Disk Management window look for your Virtual RAID Drive. If the Raid drive is listed in the Disk Management windows, it will need a drive letter assigned to it to show up in My Computer.
  4. Right click on the Raid Drive, and select Assign Drive Letter or Change Drive Letter.

Sounds like the RAID controller has failed. I would replace this first as RAID controllers are less expensive than replacing the system board, or the server as a whole.

Suggested: PERC 5i (RAID 0/1/5) or PERC 5iR (RAID 1 or 0 only)

ATA/IDE has nothing to do with SATA. Ignore.
Try plugging in the drives into the non RAID sata ports on the motherboard. I think when you disable raid you also disable the raid ports. You should have another set of sata ports on the motherboard, probably a different colour.
