                    Added some new functions which allow for more direct control of the drive
                    Remove the Erase function as discovered you just need to write a longer track to ensure you clear the gap.  Workbench writes 13630 bytes per track. The first part is filler at 0xAA
                    Added support for disk change notifications support (requires small hardware modification below)
