I just dropped my 200GB hard drive into a Firewire drive enclosure, but I never thought about whether or not to leave it powered up all the time or eject it and turn it off when I'm not using it. I'm using it to store media (movies, music, etc.) so I don't need to access it all the time. I want to do what's best for the drive and I don't know if leaving it on whenever the computer's (PM DP1.8) on is a good idea. What do you do with your external drive? Thanks in advance.
