Repartition an AirDisk When I first set up my 1Tb external disk with my AirPort Extreme I partitioned it into two 500Gb disks, one for Backup and one for Media storage but I have no memory of how I did this. I seem to remember being prompted when I first connected the disk.

Now, over a year later the backup partition is filling up but I don't really use the media partition at all. So, i'd like to know if it's possible to re-partition this disk into a 800/200Gb split without wiping the disk and starting my backups over again?
Disconnect the External Hard drive from the Airport Extreme and connect it directly to ur Computer, then resize the partitions in disk utility.
