Well, besides the implications of damaging the drive, which we'll assume is "fixed" because of the "kit", there's the fact that the drives are mounted. I would think that with some hacking, you could get the drive to work like a cdrom. With a cdrom you can unmount, change, and mount a new one. The only problem then, I would think, would be the BIOS freaking out because you just swapped a 500MB drive for a 7TB drive :) I would have no clue how to go about this, my assumption is that you'd have to have a program that manipulate the BIOS, or a program to "bypass" anything the BIOS cares about. I don't even know how much the BIOS has to do with the computer once it is fully booted, so these are just speculations. Michael Porter ocean@ecenet.com Artem Koutchine wrote: > This is a bad idea.
