i have a current pogoplug with the 4 usb ports.  i have been running seven seagate and maxtor drives some on a hub with no issues.  today i tried to add a 3tb seagate that i formatted both as journaled and unjournaled.  the hub recognizes the drive as a light goes on when its plugged in and you can hear it spin up.  i have tried plugging the drive into the hub - no luck and i have tried unplugging all other drives and just have the 3tb seagate plugged in and no luck.  the macs at home recognize the 3tb seagate but pogoplug does not.
