Safe Removal of Removable Media
If the Removable Media is used in an application, the Removable Media device requires
changing by the operator, and the application is attempting to write to the Removable Media
when it is removed, the screen designer should create objects that allow the operator to
temporally halt access to the Removable Media. This prevents corruption to the file system if
the Removable Media is removed during a file write sequence. The graphic objects should set
OCS register %SR174.1 (when requesting the card be removed) and provide an indicator based
on OCS register %SR174.2 (which indicates that it is safe to remove the Removable Media).
