This page contains a truly great hack to force XP’s disk manager to offer disk mirroring.
Microsoft frequently disables functionality to distinguish their products from one another. The difference between NT workstation and server was a few registry keys. Here, the hack is a little more complicated, but not for emacs or vi users.

Of course, you will want to back up the original files. And this hack voids warantees, etc…

Note that the change in dmconfig.dll isn’t quite right. There should be only 4 null bytes after WINNT, not 7. This changes the file size and the offsets. Very bad.

UPDATE: Happy 1000th post, taskboy.
