That type of error is also typical of Promise and other inferior IDE cards. using IDE ports on motherboards, and using 3Ware cards we rarely see this issue. Using Promise we frequently see it. Also, cables are important, I agree. Yellow Teflon/TPE cables make a big difference. The cheap grey ones are not suitable for this type of use. With our best regards, Maurice W.
