When Your SSD Says No: Overcoming ‘Not Supported’ Errors on Kingston Drives


“I recently purchased a Kingston SA400s 1TB internal SSD, but upon connecting it to my computer, it seems to be non-functional. Despite enabling the SATA port, I’m encountering an error indicating that the device is not supported. Could you provide guidance on resolving this issue, or is it necessary to consider acquiring an alternative SSD?”


When you encounter an issue where your newly purchased Kingston SA400s 1TB SSD is not functioning as expected, it can be quite frustrating. The error message indicating that the device is not supported adds to the confusion. However, before considering the purchase of an alternative SSD, there are several troubleshooting steps you can take to potentially resolve the issue.

Firstly, ensure that all cables connected to the SSD are secure and undamaged. Loose or faulty cables can often be the culprit behind detection issues.

Step 2: Initialize the SSD

If the SSD is new, it may need to be initialized. You can do this by going to ‘Disk Management’ in Windows, right-clicking on the SSD, and selecting ‘Initialize’.

Step 3: Assign a Drive Letter

In some cases, a new SSD might not show up because it doesn’t have a drive letter assigned. Again, in ‘Disk Management’, right-click the SSD and select ‘Change Drive Letter and Paths’ to assign a letter.

Step 4: BIOS/UEFI Configuration

Incorrect BIOS settings can prevent an SSD from being recognized. Access your BIOS setup and navigate to Storage Options or SATA Configuration. Here, you might need to switch to IDE Compatibility Mode or ensure that the SATA port is enabled.

Step 5: Update SSD Firmware

Outdated firmware can lead to compatibility issues. Check the manufacturer’s website for firmware updates for your specific SSD model.

Step 6: Test on Another Computer

To rule out the possibility of a defective SSD, try connecting it to a different computer. If it works on another system, the issue might be with your computer’s motherboard or settings.


If, after following these steps, your Kingston SA400s 1TB SSD is still not recognized, it could indicate a faulty SSD or a compatibility issue with your system. In such cases, contacting Kingston’s customer support for further assistance or considering an alternative SSD might be necessary. Remember to back up your data regularly to avoid data loss during such troubleshooting processes.

By taking a methodical approach to troubleshooting, you can often resolve issues without the need for immediate replacement. Patience and a bit of technical know-how can go a long way in addressing hardware detection problems.
