Experiencing an SSD error like “Mismatch Detected” on Windows 11 can be frustrating. This error often indicates a problem between your SSD drive and the system’s expected configuration. Fortunately, there are several straightforward steps you can follow to resolve this issue quickly.

In this guide, we will walk you through simple, easy-to-understand solutions. You don’t need to be a tech expert to follow along. Just take your time and follow each step carefully.

Fixing this error helps maintain your SSD’s performance and prevents potential data loss. Let’s get started with some quick checks before diving into the fixes.

By the end of this article, you’ll have multiple ways to troubleshoot and solve the mismatch error on your SSD with Windows 11.

Quick Note: Prerequisites and Initial Checks

Before you begin troubleshooting, make sure of the following:

  • Backup Important Data: Always back up your important files. Although these steps are safe, it’s good to be cautious.
  • Check SSD Connection: Ensure your SSD is properly connected to your PC. A loose cable can cause detection errors.
  • Windows Updates: Confirm that your Windows 11 is up to date. Sometimes, system updates fix hardware compatibility issues.
  • Power Settings: Check that your PC is plugged in and has a stable power supply.

Step 1: Restart Your Computer

Sometimes, a simple restart fixes temporary glitches. Restarting refreshes system memory and resets hardware communication.

  1. Click the Start button.
  2. Select Power and then Restart.
  3. After rebooting, check if the SSD error still appears.

This basic step eliminates minor issues and should always be your first try.

Step 2: Update SSD Firmware

Firmware controls how your SSD operates. Outdated firmware can cause mismatch errors. Updating it helps your SSD work correctly with Windows 11.

  1. Find your SSD manufacturer’s website (for example, Samsung, Crucial, Western Digital).
  2. Look for the Support or Downloads section.
  3. Search for your SSD model and download the latest firmware update tool.
  4. Follow the provided instructions carefully to update your SSD firmware.

Important: Do not interrupt the update process, as it could damage your SSD.

Step 3: Update Storage Controller Drivers

Your SSD communicates with Windows through storage controller drivers. Outdated or corrupt drivers may cause mismatch errors.

  1. Press Windows + X and select Device Manager.
  2. Expand the Storage controllers or IDE ATA/ATAPI controllers section.
  3. Right-click on your storage controller device and select Update driver.
  4. Choose Search automatically for updated driver software.
  5. Let Windows find and install any updates. Restart your PC afterward.

If no updates are found, visit your PC or motherboard manufacturer’s website to download the latest drivers manually.

Step 4: Check SSD Health Using Windows Tools

Sometimes, the error may be due to SSD health issues. Windows has built-in tools to check disk health.

  1. Open Command Prompt as administrator (search for “cmd,” right-click, and select “Run as administrator”).
  2. Type the following command and press Enter:
wmic diskdrive get status

If the status shows “OK,” your SSD is healthy. If it shows “Pred Fail” or any error, your SSD may be failing.

Step 5: Run Windows Disk Check Utility

Disk errors can cause mismatch problems. Running a full disk check can fix corrupted files or bad sectors.

  1. Open This PC.
  2. Right-click on your SSD drive and select Properties.
  3. Go to the Tools tab.
  4. Click Check under the Error checking section.
  5. Follow the prompts to scan and repair the drive.

This process may require a restart to complete.

Step 6: Reset BIOS/UEFI Settings to Default

Sometimes, incorrect BIOS or UEFI settings cause SSD detection errors. Resetting to default settings can resolve mismatches.

  1. Restart your computer and enter BIOS/UEFI setup (usually by pressing F2, Delete, or Esc during startup).
  2. Look for an option to Load Default Settings or Reset to Default.
  3. Save changes and exit BIOS.
  4. Check if the SSD error persists after booting into Windows.

This step helps if recent BIOS changes caused the mismatch.

Alternative Method: Use Windows Disk Management to Re-initialize SSD

If the SSD is recognized but shows errors, re-initializing the drive can sometimes help. This method is more advanced and may erase data.

  1. Press Windows + X and select Disk Management.
  2. Locate your SSD from the list.
  3. Right-click the SSD and select Initialize Disk (if available).
  4. Choose the partition style (MBR or GPT) as recommended.
  5. Follow prompts to complete the process.

Note: Initializing the disk will erase all data. Backup before proceeding.
