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.
