Hi all! I am a switcher going on about a month now and getting settled in. Question about external hard drives: I've read in posts that people never power off their external HD, and that the constant on/off actually damages the HD. Is this true? Can't remember where I've read it cuz I've been reading so much in these and other forums lately. I am running a MBP, and I power off the MBP when I'm not using it. If the answer is that I shouldn't power off my external HD, can I do that even if I power down my MBP? Thanks in advance for the answers, and thanks to all you guys in this forum for helping me through my early Mac days (and I suspect my later ones too).
