Hi everyone. I know there are already threads about external drive cases, but I can't figure out if some of the problems I've read about (specifically Macally) will affect this particular hard drive. It will be used as an extra system backup. Trying to decide between: Macally Good price, but reported power issues. Icy Dock Good price, but reported flimsy power cord connection that falls out easily. Also issues with Firewire 800? OWC (Mercury Elite AL-Pro) Most expensive. Has anyone used the WD 6400 AAKS with any of these brands? Any comments welcome. Thanks.
