What does #38 mean?

An internal fault has been detected within the drive itself, indicating a potential hardware or software malfunction that prevents the drive from operating correctly. This type of fault requires internal diagnosis and, if left unresolved, risks further damage to the drive or complete system failure.

Complete Troubleshooting Guide

  1. 1

    Power OFF the drive completely, wait for 30 seconds, and then power it ON again to attempt a reset.

  2. 2

    If the alarm persists, refer to the detailed Operating Instructions for any associated sub-code numbers that may provide more specific fault diagnostics.

  3. 3

    If basic troubleshooting does not resolve the issue, return the drive for inspection and repair, especially if it is covered by warranty.
