I am trying to connect 3 external hard drives (2 of them are one partition only, and one is partitioned into two partitions) through a USB hub to my Airport Extreme, and only one drive and one partition of the split drive are showing up. To rule out the USB hub, we connected each drive to the Airport Extreme directly, and still only the drives that showed up through the USB hub showed up when connected directly. The others show up in Airport Utility as drives, including the drive in 2 partitions, but are not accessible by any means I know. Please help. Thanks.
