From a previous post, it was recommended that I go the route of using the USB port on my Time Capsule to connect a USB hub for a printer and external HD. The external HD will be used for Time Machine backups for two MacBooks (the internal drive is too small and I do not want to disassemble the TC). I am looking for a good external HD recommendation for the purpose of plugging into a USB hub on the Time Capsule and using it for backups. What drive is recommended, and where should I purchase it from? Also, what USB hub should I use for this (printer and HD)? Thanks.
