You using AirPort Utility to configure the drives? They will need to be formatted with HFS+ if they haven't been already.
Now that the external drive is working, I'd like to access it from outside my network. I don't think its possible though. I'd like to be able to access the contents of the external HDD plugged directly into the Airport Extreme from anywhere, using either a mac or a pc.
Doing so would let me dump my old computer currently used as file sever with remote desktop function.
I'm also curious for a comparison between internal and external storage. My Time Capsule is due in on Wednesday and I have an external on hand that I may do some comparisons with.
It's USB2, so don't expect much - you'll be limited by that if nothing else.
