Yeah exactly. The only problem is that everything fun I have on my computer is on the one hard drive, and it's £250Gb (almost full, too). That's a hell of a lot of DVD-R's whichever way you cut it. I really need to buy an external hard drive to back everything up to. So what I'm saying is that if the MBR screws up and I can't fix it, I'll lose looooads, not just my Windows install.
