Make sure this card doesn't have one of those switches that has to be set for 4 gigs. Otherwise, try formatting with the PC and then back with the Book Port again.

I did the formatting on the BP with 1,3,D,F When I plug in the USB, I get the Windows sound that something is connected, but the BP software says not connected. Is there something else I need do? Thanks!
