Hi, I recently bought a WD Passport Essential to back up my Macbook. When I plugged in the WD Passport, my Mac asked if I want to use this storage device for my Time Machine. 1. Should I use the WD Passport as the Time Machine storage device or use the WD Passport software to run back-ups? 2. If I use it for my Time Machine, will I be able to access my files on other machines? 2. Is it possible to have files stored on the WD Passport, such as photos, but not have those files on my Macbook... if I am using the Passport for back-ups? Thank you so much! I apologize if this is the wrong area... I just joined the group and feel a little overwhelmed by all the info. Thanks!
