General Troubleshooting Information
Keep the following points in mind when troubleshooting disk problems.
1.

Do not save translations or announcements on the d isk if unresolved Disk

Drive or Host Adapter prob lems are present.

If there is something wrong with the MSS, any attempt to save translations
or announcements could destroy a good cop y of the files on disk.
2. When multiple error conditions are p resent, check for Host Adap ter and
Tape errors first.
Maintenance software cannot always d istinguish between errors cause d
by the Disk Drive, and errors ca used by the Host Adap ter or Tape Drive.
