This command enables or disables Data Safe Mode.

An example of the IOCTL_SET_DATA_SAFE_MODE command is

#define IOCTL_SET_DATA_SAFE_MODE        CTL_CODE(IOCTL_TAPE_BASE, 0x0824, 
METHOD_BUFFERED, 
FILE_READ_ACCESS | FILE_WRITE_ACCESS )
DATA_SAFE_MODE tapeDataSafeMode;
...
DeviceIoControl(gp->ddHandle0,
               IOCTL_SET_DATA_SAFE_MODE,
               &tapeDataSafeMode,
               (long)sizeof(DATA_SAFE_MODE),
                NULL,
                0,
                &cb,
                (LPOVERLAPPED) NULL);
