Hi Gary, I want to start using Time machine and I have an external 500gb hard drive. On that hard drive I have about 1/2 already used up and would like to use about 150gb of that free space for time machine. Is there a way to set that up without deleting all the content I have on that drive already? My macbook pro doesnt have enough space to move all the content onto its drive to be able to do it from scratch.
