At first I thought your problem would perhaps be because you were using the 40 conductor cable instead of the 80 conductor. But a quick Google/linux on 'ide0: Speed warnings' reveals a lot of people having similar problems to you. The issue seems to revolve around chip sets and the kernel. One person reported being able to get full disc speed despite the error message using hdparm -c1d1X69 It might be worth asking on MandrakeExpert (Yes, I know they can be slow replying, but that is where Civileme devotes his time now) derek -- ---------------------------------- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
