NVMe SSD Locked in Read-Only Mode

What is NVME_READ_ONLY?

The solid state drive controller detects media wear or flash array errors and locks itself in read-only write-protection to prevent further data loss. The user can read files but cannot save, modify, or format the drive.

Common Causes

• SSD write endurance limit (TBW) exceeded
• Critical controller hardware failure
• Excessive bad blocks

Step-by-Step Fix Guide

• 1
  Backup all files from the drive immediately

  Backing up data is your immediate top priority. A read-only locked SSD is near complete physical failure.

• 2
  Buy a replacement SSD

  Replacing the drive is the only way to recover normal write operations.

• 3
  Use SSD manufacturer software to check spare block count
