I have a Nexstar 3 eSATA enclosure and have ordered a 640gb WD. I currently have a 400gb which is gonna be going in the enclosure for backup of important files only that I can't get back in case of HDD failure. What I need to know is when is it safe to add/remove the enclosure? Do I just run the brack to my onboard SATA or do I need a certain SATA card?
