 Hi,
 
 Force this eSATA port controller to 1.5 Gbps works for me.
 Thank you.
 
 It seems that this motherboard/chipset can' t support 3 Gbps. Even with
 other O.S. it don' t works all the time.
 The same eSATA cable and external enclosure works well at 3 Gbps with
 two other motherboard.
 
 Best regards,
