Is it possible make time machine backups to an disk plugged into an Airport Extreme base station when the disk is formatted as Mac OS Extended Journaled?

I've tried formatting the disk in this way, but whenever I connect it to the base station Airport Utility gives me the "disk needs to be repaired" error message (with no instructions on how to repair it). Tried using the repair tool in Disk Utility, but that had no effect.

Connecting the disk to the drive formatted as Mac OS Extended (with no journalling) seems to work, but I'd rather have journalling turned on for the extra stability that it offers.

No, the AirPort Extreme Base Station does not support journaling. It only supports regular HFS+.
