I have been using my MBP + 500GB Seagate on an Airport Extreme. It works flawlessly for a few days, until I out my MBP to sleep, or turn it off. Then it gives me an error code -6580 and I have to go and delete everything and start with a fresh partition. This has happened 5 times now and it is driving me crazy 
Has anyone got this working on an external hard drive over an airport extreme?
