** First off: Apologies if this question has been asked before, I searched and could not find it ** OK - I have a 500GB Time Capsule, and very slowly my drive is filling up, and that's only with one Mac (I think there's about 25GB left - and no other stuff is on it except for the TM backup). I was wondering if there was a way to add an external drive into the Time Capsule via USB and extend the overall capacity, as I only seem to be able to choose it as a separate backup location. Obviously I don't want to have to buy a bigger USB HD when I'm running low on space. Also, I'm gonna be getting an iMac (As soon as Apple decides to announce new ones!) and obviously this might prove to be a problem with HD space available. Thanks for your help!
