* Make ModeSelect() non-const Signed-off-by: Klaus Kämpf <kkaempf@gmail.com> * Implement ModeSelect for scsicd and honor sector size setting. DEC's VMS can't handle 2k sector sizes and uses ModeSelect6 to set the sector size to 512 bytes. Fixes #1397 Signed-off-by: Klaus Kämpf <kkaempf@gmail.com> * Test sector size setting via ModeSelect in SCSICD Signed-off-by: Klaus Kämpf <kkaempf@gmail.com> * Re-calculate total blocks when sector size changes Signed-off-by: Klaus Kämpf <kkaempf@gmail.com> * Reset CD data tracks after sector size change The track calculation is based on sector size and must be reset after change of sector size. Signed-off-by: Klaus Kämpf <kkaempf@gmail.com> * resize cache after change of sector size The disk cache is based on sector size and must be resized when the sector size changes. Disk::ResizeCache needs a `raw` parameter, make this value accessible from the current cache.
