Igor, when I begin shutting down, yes, it spins. But I can't see it during all the shutdown process... after a while, windows does a logoff and starts the shutting down routine... it passes to the "saving user's preferences" (or something like that) screen and then it stays a lot of time in the next message screen ("windows is shutting down")... during this message, at first, some disk access is performed, but only in the very begining. After this very begining period, comes a looooong period where no disk access is performed and the shutting down process seems it won't finish anymore. After a few minutes (about 4 or 5 minutes) the shuttdown process finish successfully.
