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.

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

Thanks in advance.

  1. The first thing I'd do is go into the BIOS and reset it to the default setting and seed if this fixes. If it didn't, I'd try another cable.
