Motherboard downgrades from ultra/100 to ultra/33

Hi, ever since I played around with the hd cables on my motherboard, I get this message everytime I turn the pc on.

"An ultra ata/66 drive (or faster) is connected with a 40 pin IDE cable on the secondary channel. Drive speed is downgraded to ultra/33 mode dma."

But my hard drive is a Western digital 200 gig UDMA/100 And I'm connecting it with a 40 pin 80 conductor cable which was the cable it was using before I got these messages.

I was checking the manual and it says the cable and connector I'm using is for UltraDMA 100/66 which is what hard drive is.

Yet this error message says I have a ultra ata and not an ultra dma drive and is defaulting it to ultra/33 mode dma.

My drive is this one. http://www.tomshardware.com/2002/10/11/western_digital_...

My drive also has a IDE Raid connector. Was I supposed to plug it in there?

Thanks in advance.
