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,
