Motherboard downgrades from ultra/100 to ultra/33 Tags: Motherboards Cable Last response: February 10, 2007 10:24 PM in Motherboards Share LordByron February 10, 2007 5:39:45 PM 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.

If it didn't, I'd try another cable. Can't find your answer ? Ask ! Publish Related resources: ForumWindows XP Pro SP3 ForumWD1000 only 30 GB? Forumnew build (or upgrade old?) almost narrowed down...
