What can I do if a drive is in "Warning," "Critical," or other abnormal statuses?

Purpose

This article aims to help you understand the meaning of each drive status and provides guidance on what to do if the status is abnormal.

A drive is likely defective and needs replacement if it has entered Warning, Critical, or any other abnormal statuses.
