I have a 2TB time capsule and i only use it for time machine for a 500GB imac and my itunes library which is currently 477GB in size. I am missing 1TB of space and itunes is not letting me store any more information. Finder shows 2 folders under my time capsule, .sparebundle and itunes. when i choose "get info" on sparebundle it keeps saying "calculating size" ... i have also deleted old back-up folders but still no space. I also deleted 10-20GB of itunes files and it still shows 477GB folder size. Any help?
