I just got a 500GB 7200RPM G-Drive mini external hard drive, to use with Time Machine on my home iMac. I was wondering if I should keep the drive on at all times or should only start it up when I am going to manually backup my data. What are the pros and cons to doing either of these methods? Any help would be welcome. Thanks.

Plug in when you want to backup your data to that hard drive using Time Machine, if not in use just plug it out. There are no pros but the cons is that your hard drive may get corrupted easily.

Ok. Thanks for the info.
