look at the two InfoTool pics below.
in the second you see what my system used to be like. there's the Primary and Secondary IDE Channels of the motherboard, Silicon Image Sil 3112 SataRAID Controller (built into the motherboard) and Silicone Image Sil 0680 ATA-RAID controller on a PCI card.
however in the first pic there's something new - D347PRT SCSI Controller (it shows up in device manager too).
i've no idea what this is and why it suddenly appeared on my computer. needless to say i don't have a SCSI controller or drive in my system.
i can't think of anything i might have done - no hardware change etc.
just this - i started using a SATA drive (you can see it in the first pic). but then it would appear under the motherboard's SATA controller (as it does).
