I saved a mac server and 7tb raid from the trash. when i run a single fibre cable from the raid to the server, and i access the raid through disk utility (in os x 10.4.2) it says there is only 2.7tb. I realize I'm only accessing half the array but shouldn't I see 3.5tb? what am i doing wrong, i have green lights across the board, does that indicate all drives are working properly?
