I've added disks half a dozen times without blowing away any MBRs. Even the Windows blowing away the MBR is an annoyance, not a disaster since it is easy to rewrite. Whatever pickle you find yourself in seems to have to do with more than just adding a disk or Windows killing your MBR. >I need to be able to operate on my clients' disks.

Dual boot machines are really common (I have three here) and despite adding disks to each of them at some point in their lives, I've never ended up with anything going wrong. > A >bootable external USB drive may be the ideal "Fixit" drive ...

I'm not denying that you're in a pickle, but that is not a necessary consequence of adding a disk. --Alex
