1. Verify Servo Null and Alignment (Refer to Chapter 6, Section 3 of this manual if necessary)
a. Verify the Servo Null as described in Chapter 6, Section 3.
b. Check the Head Alignment using the procedure in Chapter 6, Section 3. Head alignment may
shift with extended use or during shipment. Realign any heads that are out of alignment.
c. Remove the CE alignment pack from the drive and reinstall the scratch pack.
d. If any readjustment was done on the Servo Null or Head Alignment above, you must format the
scratch pack and run at least 6 passes of ZDKP FMTR again. For details of the Formatter
program, refer to Section 3-5 of this chapter.
2. Disk Reliability
This section assumes that the scratch pack is installed, has been formatted, and 6 passes of ZDKP
FMTR have been run on the disk pack. Dual Drive Systems can run this section on both drives
simultaneously.
a. At the disk drive, press START if the pack is not spinning, wait for the READY LED to light, and
press the WRITE ENABLE switch. If running dual drives perform this on both drives.
b. Mount and load the DTOS tape. If necessary, refer to DTOS Vol #1, Part 1, for details.
