Importance of Compaq-Approved

Tape Cassettes

Compaq-approved tape cassettes are thoroughly tested to meet high-quality standards. Before Compaq recommends a tape cassette, the quality and reliability of the magnetic media and the cassette are evaluated. Do not use unapproved tape cassettes because they may not be compatible with Compaq tape drives.

See Chapter 1 for a list of Compaq-approved tape cassettes.

DAT AutoLoader Cleaning

Recommendations

Of the tape drives available today, DAT drives are more susceptible to buildup of contaminants. If a DAT drive is not kept clean, increased errors will occur. Recommendations for cleaning DAT drives are as follows:

If the CLEANREQ message is displayed on the front panel.

When using new tape cassettes, clean the drive heads with a cleaning cassette after every 8 hours of use for 5 initial cleanings.

When using tape cassettes that have already been used 5 times, clean the drive heads with a cleaning cassette after every 100 hours of use.

If you begin to experience read or write errors, format failures, or a number of bad blocks, clean the head and capstan 3 more times before concluding that either the tape or the tape drive is defective.

In a dusty environment, one cleaning cycle may not fully clean the DAT AutoLoader drive read/write heads. If backup software reports errors, clean the drive again. No more than four cleanings will be required to ensure that heads are fully clean.

NOTE: Cleaning cassettes can be used approximately 50 times. An expired cleaning cassette will eject immediately without cleaning.

CAUTION: No other periodic maintenance is required. Do Not use alcohol or cleaning solution to clean DAT drives. Do Not clean read/write heads with a cotton swab. Fibers from a cotton swab can cause permanent damage to the head.
