When I go to airport utility, no disk is recognized. I've tried restarting and resetting the time capsule. If I go to the disks tab, the partitions list is just blank.

I put in a WD Green 3 TB disk(WD30EZRX), everything came apart and went together fine, but when I started it back up, still have the same issue of "internal disk needs repair". Any ideas on what the problem might be?
