rStatus  On exit, the driver must place a DevStatusWord here.  Always
set the Done bit (bit 8).

If the disk in the drive is removable, clear the busy bit
(bit 9).  If the disk is non-removable, set bit 9.

Notes:   Only drivers capable of device Open/Close-processing need
support this request (see Device Attribute bit 11).

  This is the driver "catch point" for DOS fn 4408H (IOCTL does
drive use removable media?).
