It has been reported that doing this using a USB > port will brick the drive! I don't use USB for drives, except the USB stick thingys. I have a question sort of related to this. Anyone can share info. I see boxes that hold drives in them and connect via ethernet or something like that. Do those work really well? I thought about getting one someday but I don't know what they do and how they do it EXACTLY. Is it like a small puter in there or some other means of getting the data across? Right now, I like having my drives in my Cooler Master case. The fan blows right on the drives so they stay nice and cool. But, I have given thought to having the non OS drives in one of those little boxes, maybe using RAID and mirroring the data on two drives. Just what magic is in those things?
