This issue seems to appear on a variety of Intel SSD devices.

In some cases, the error is accompanied by other issues like freezing and lagging, strange file corruption problems, and even failed Windows Update installations.

The error message is being displayed when users run the Full Diagnostics Scan from the Intel SSD Toolbox.

The scan stops at different percentages but shows the same error message: Data Integrity – Error: Data mismatch detected. Contact your reseller or local Intel representative for assistance.

If you’re worried that your SSD might be faulty, that may not be the case. In this fix article, we will explain why that is the case, and also what you can do to troubleshoot this issue.

Read on to find out more details.


Here’s how to solve the SSD mismatch detected error

1. Test your CPU/memory with LinX

Note: If you are using overclocking on your PC, or your CPU cooler is faulty or low quality, performing this step may cause your CPU to overheat. With modern CPUs, this should not cause any issues, but pay attention to the registered temperatures of your system and abort the process if it exceeds 90C.

  1. Download LinX and extract the files to a folder on your PC.
  2. Make sure to use a non-SSD drive if possible.
  3. Run LinX.exe.
  4. Press Settings -> set the threads to match your CPU thread count (If you use Intel i5 -> set it to 4/ If you use Intel i7 CPU -> set this to 8).
  5. Press the All button -> set the Run option to 10 minutes -> Press Start.
  6. Check the results of your tests and take the appropriate measures.
  7. If the LinX testing lasts more than several hours, then it might mean that your SSD could have a problem.

  7. After modifying the options, press F10 to start the scan.

Checking the results:

  1. Press the Win+R keys and type eventvwr.exe -> press Enter to open Event Viewer.
  2. Expand the folder Windows Logs -> right-click System -> click Find.
  3. Type MemoryDiagnostics-Results -> click Find Next.
  4. Double click the result -> check the results of the test.
  5. If the result reads The Windows Memory Diagnostic tested the computer’s memory and detected no errors -> then you have no issues.
  6. If the results show errors, then it means that your RAM memory could be corrupted, thus creating problems with your SSD.
