My 2 cents This doesn't appear to be a v1.11 problem. I have had my MBR trashed with a cherry v1.00 install. It seems more like an ATAPI problem to me? The reason I say this is that I only get my MBR trashed if I _don't_ use the NoCD hack. When I start any version of Diablo II ( except v1.09 ) and I get the little pop-up asking me to insert the Play CD, at this time my MBR is trashed. If I use the NoCD hack I don't get the pop-up and my MBR doesn't get trashed.
Now this part is strange. v1.09 works and doesn't trash the MBR even if I get the Insert CD popup... strange. But when I patch to v1.11b I once again get trashed MBR.
I could not find a v1.10 patch for Windows version only for Mac and OSX so I can not verify v1.10.
My suggestion is to use the NoCD Hack and you don't have to worry about your MBR even if your user is in disk group.
