I've submitted a different version that uses
IOCTL_STORAGE_QUERY_PROPERTY. While this works for drives mapped to
directories (c: -> ../drive_c) it fails for drives mapped to Unix mount
points (z: -> /) because in the latter case we try to open the
underlying Unix device, which usually returns a permission denied
error.
