wondering if anyone can please help me.

I have:

(1) 1ft Low Profile SATA to eSATA Plate Adapter
(2) motherboard ASUS IPIBL-LB (Benicia-GL8E)(Motherboard Specifications, IPIBL-LB (Benicia) - HP Customer Care (United States - English))

the SATA to eSATA adapter works great on Windows but not for my OS X 10.6.4. Any ways I can get this to work under Mac environment?

thank you.
