Add an ATA drive to a WIN 2000 server

I have a WIN 2000 server with 3 36GB SCSI drives set up in a RAID array.  I have an 80GB WD EIDE/ATA drive that I installed, along with an ATA controller card.  The controller card (Silicon Image SIL0680) can work as a RAID controller, or as a single drive controller.  When I booted,  Windows installed the drivers for the card, but  the drive was not listed with the other drives in Computer Management.   I re-booted and entered the RAID setup utility (F3).  The card and drive were there and I was given the option to create a new set, but I don't know if I can create a RAID set with only one drive.  Also, if I create a new set, will that impact the existing PERC set?  The PERC set is the boot drive.

You want to create a RAID 0 on the ATA drive or JBOD if it's an option.  It SHOULDN'T interfere with the PERC card as the PERC Card's BIOS probably loads first and thus controls booting.
According to there are two different drivers - one for using the card as a RAID array and one for using the card without RAID array.  I would guess you have installed the RAID array version.

The PERC controller and the ATA controller are two physically different cards.  They should not interfere with each other EXCEPT POSSIBLY in terms of Booting, but if the PERC controller is seen first by the system, then even that should NOT be a problem
