I had toyed with the idea of having my second internal drive be a 500GB SATA, and putting a power switch on it, maybe mount the switch on the back. Flip the switch on, do my Acronis backups, flip it off. I don't need a second drive always powered on, and internal is faster than external. I was thinking that I would have to power it on and off before I turned the PC on, but after reading this, could it be turned on and off while windows XP is running? Probably not, since there would not be a way of 'safely disconnect device" Still, I may do it, or just get one of these things..
EDIT: Well, darn., I never noticed that the "safely remove icon" has my main hard drive listed. I guess I can turn a drive on and off while running XP. Hmmm.
