In general, you need the 80wire-40pin cable. That would be the one that's blue at the end that goes into the controller (the motherboard). But, I believe its backward compatable, and the older cable can still be used. I think the burst speed would be affected, but that's not going to be noticeable to you, in terms of speed. ---Troth ----- Original Message ----- From: Barnstoneworth To: pctechtalk@xxxxxxxxxxxxx Sent: Thursday, September 11, 2003 11:51 AM Subject: -=PCTechTalk=- IDE Cables Funny how, in talking about a problem someone else is having, you come across something you might have a problem with yourself!! Are there different IDE cables for ATA 133 hard drives than ATA 66/100? Reason I ask is that I've got an 80gb ATA 133 drive as my master and 20gb ATA 100 as it's slave, and I'm using the same cable I had when I had the 20mb drive as the master and an 8gb ATA 100 as the slave.
