1. 4 8 26 Allow Multi Track Corrected Errors 67 This option allows the drive to accept a Read After Write status of more than one corrected error MTEC as a good status This option is provided for applications geophysical which are quasi real time when writing and which can accept some loss of data during subsequent Reads When the option is disabled Default only single track corrected errors are allowed during normal writes Multi track recorded errors are only allowed if the errors occur in different track groups Enabling this option will improve write performance by allowing MTEC errors regardless of what tracks are affected NOTE If additional errors occur during later reads an Unrecoverable Read error may occur 4 8 27 Motor Torque Calibration 70 This diagnostic calculates the torque constants for the supply and takeup motors then stores them in the non volatile memory While the diagnostic runs the Active indicator lights when it finishes 00 appears at the hexadecimal display NOTE If an error code 54 occurs this diagnostic must be run before loading a cartridge if a cartridge has already been loaded the power to the drive must be cycled 4 8 28 Unlock Factory Mode Enable Tests in the 80 s Series 99 The factory mode was created to avoid the inadvertent selection of the factory only tests 80 s series and will always default as disabled To enter into the factory mode this test must first be a
