Would plugging an external HDD into the USB port of the Time Capsule allow me to transfer files USB to USB, so to speak (with the internal HDD inside the Time Capsule)? previously I had the Airport Extreme + an external HDD for Time Machine and various files. Last night I tried to transfer those files to the Time Capsule and it gave me an error for the Time Machine backups and is estimating a week (!) to transfer everything else via my home network. I left it going overnight and it got as far as 26.5GB...so ya.
