Background: I noticed all of that when testing the SetCurrentDirectory("c:\\").
Took me a while to understand why chmod stopped working. On XP HOME there
is no security gui, so I had to use cacls. Not nice.

By the time we call fs_info::update, we have done a successful
GetFileAttributes for a file on the disk. So we know we can access it OK.
I can't imagine any mechanism whereby GetVolumeInfo would return ACCESS_DENIED
if there were no acls. For remote drives has_acls is off by default (smbntsec).
