Windows - Utility Program (ntutil) SYNTAX: set_device_parameters compression = n for example, set_device_parameters compression = 0 FUNCTION Tested: This command calls the device driver SetTapeParameters entry point with an operation of SET_TAPE_DRIVE_INFORMATION. The compression value is a required parameter with the command. compression - device compression On or Off (0 for Off, any other value On). set_media_parameters (block size): SYNTAX: set_media_parameters block_size = n for example, set_media_parameters block_size = 0 FUNCTION Tested: This command calls the device driver SetTapeParameters entry point with an operation of SET_TAPE_MEDIA_INFORMATION. The block_size value is a required parameter with the command. block_size - device block size setting (0 for variable). set_reset_write_protect: SYNTAX: set_reset_write_protect wp = x for example, set_reset_write_protect wp = 1 FUNCTION Tested: This command calls the device driver DeviceIoControl entry point with an operation of IOCTL_SCSI_PASS_THROUGH, a CDB[0] of MODE_SELECT (0x55), and a mode page of 0x23. Refer to the appropriate hardware reference manual for details on Associative and Persistent Write Protect. The write protect value on the mode page is updated based on the wp parameter, where wp is: 1 - Set Associative Write Protect 2 - Set Persistent Write Protect 3 - Set Both 4 - Reset Associative 8 - Reset Persistent 0 - Reset Both space_eod: SYNTAX: space_eod for example, space_eod FUNCTION Tested: This command calls the device driver SetTapePosition entry point with an operation of TAPE_SPACE_END_OF_DATA. It attempts to space to the end of data on the cartridge in the tape device special file opened previously. test_unit_ready: SYNTAX: test_unit_ready n for example, test_unit_ready 1 FUNCTION Tested: Appendix D.
