The following two statements are from the Wikipedia entry on eSATA
I am not sure what they mean by a “passive adapter”. What would an “active” adapter be, and would it be located in the computer or in the external hard drive enclosure? Does the second statement mean that if I install an eSATA bracket in my computer (i.e., just a length of cable with plugs either end that connects an L type SATA socket inside to an I type in the backplane) and then try to connect to my external eSATA hard drive to the backplane socket with a 2 metre cable, it will not work?
If so, that sucks. My CPU is under my desk, on the floor, and a 1 meter cable is not long enough to reach to anywhere conveniently accessible. (Two meters would be plenty, though.)
