Chapter 5 Troubleshooting and Diagnostics This Chapter . . . p provides information on drive warning lights and the Media Warning message. p describes the effects of high humidity on the AIT-70D/100D. p explains what to do when you need technical support.
Warning Signals The drive used in the AIT-70D/100D employs three LEDs on the front panel to indicate SCSI activity, cassette status, and drive fault conditions through a pattern of codes. The LCD also displays error messages as described in the following section. LCD Error Messages Whenever an error occurs, perform the actions listed in the following table. If the error message reappears, call the ATAC or you reseller for assistance.
The Media Warning message is also cleared from the drive by loading a new tape, or by cycling power to the AIT-70D/100D.
Causes of the Media Warning Message The Media Warning message appears whenever the drive has determined that low level error performance has degraded to a point where drive head cleaning is absolutely required. It does this by counting the number of C3 (soft) errors as well as the RAW (Read After Write) errors over a number of Mbytes. When a predetermined error rate threshold is reached, the drive displays the warning.
