I now have a clearer impression of the situation.
I had erroneously understood windows was actually running from that slice and
that it must have really been bigger than it appeared.

Sounds like an excellent idea. Perhaps windows is seeing the slice as a fs
it knows about but finds it unformatted, so is offering to do that for you.
So maybe setting sysid to zero (which I think registers as an undefined
slice) will stop windows making the offer.

Whatever else I can't see how this would make the situation worse.

Good luck,
