3.3 PREVENTIVE MAINTENANCE
Preventive maintenance is limited to periodic dusting of the surface of the drive. No
lubrication or further cleaning is required or recommended. D2246 disk drives contain
no parts that require scheduled adjustment or replacement.
NOTE
The air filter in the sealed head/disk assembly can-
not be replaced or cleaned.
As part of a periodic preventive maintenance routine, run system-specific (software)
diagnostic programs or use the diagnostic panel to run offline test procedures (see
Appendix C).
3.4 TROUBLESHOOTING
If a fault occurs, attempt to isolate the fault to the host, to the host controller, to the disk
drive, or to another connecting component. For faults isolated to the disk drive, use the
troubleshooting procedures outlined in the following flowcharts. These procedures
localize the fault to a specific drive component.
