IOCTL_IS_DISK_WRITABLE may be called and get an incorrect response. If

NOTE: perhaps setting the updaterequired byte to one should be done here.
if so, it relies upon the setting of a 32-byte value to be an atomic
operation. unfortunately, there is no simple way to notify a class driver
which wants to know that the device behavior requires updating.

to minimize the number of asynchronous notifications, an application may
