I think that if you use eSATA you probably need dedicated eSATA controller ports. eSATA standard specifies a higher voltage for the longer cable distances. Judging from the sporadic problem reports, Promise TX4 is probably not the best at signal purity to begin with so using it for eSATA pushes it over the edge. Hope that helps, - Andrew
