I have a question about using photoshop/bridge from an external hard drive. Having been burning off my photos onto CDs for the past few years, I have been told it would be better to back them up onto an external hard drive (to speed up my computer and to have another back up... I am a heavy, heavy photograph user). My questions are: 1. Is it possible to completely back up my hard drive, and then use this hard drive in an ongoing capacity (sorry, I don't know the technical term!) on a daily basis using photoshop/bridge? Would this be incredibly slow? 2. What does partitioning (a word I've stumbled across in my googling) do/is this how I should be doing the above? My main objective, other than having an external back up, is to take 'bridge' and all my photographs off my internal hard drive. Does this make sense? Sorry, I'm not very technically minded, but would appreciate any advice! Thank you.
