Why Does the BIOS Not Detect an SSD or HDD?

When setting up a new computer or upgrading your storage, it's essential that your BIOS detects both SSDs and HDDs correctly. However, you might encounter issues where the BIOS does not detect an SSD but detects an HDD. This guide will help you troubleshoot this problem and ensure proper detection of your SSD.

Common Issues and Troubleshooting Steps

Case 1: BIOS Not Detecting a Solid State Drive (SSD)

If you're experiencing the issue where the BIOS does not detect an SSD but detects an HDD, try these troubleshooting steps:

Check SSDEnabled: Ensure the SSD slot is enabled in the BIOS settings. For Intel 10th Gen on a B560 motherboard, the first NVMe slot might be disabled. Try using the second NVMe slot instead. Regain BIOS Detection: If you recognize the SSD in the BIOS, your operating system should detect it. However, if you're using Windows 7, you might need to install a driver for NVMe SSDs. Some Western Digital SN series SSDs might need more time to respond to the system boot, causing the BIOS to miss the signal. Simply restarting the system may fix the issue. Format SSD: If you're using an SSD out of the box, it might not be formatted correctly. Use the Disk Management tool to see if an automatic format is needed. This process is usually straightforward.

Case 2: Incorrect Drive Connections

Ensure that your SSD is connected correctly:

SATA SSD: Check the power and SATA cables to confirm they are properly connected to the SSD and motherboard. M.2 SSD: Verify if your M.2 port supports SATA or NVMe. Incorrect port compatibility could cause the SSD not to be detected. NVMe SSD: Ensure your M.2 port supports NVMe. Incorrect port compatibility can prevent the NVMe SSD from being detected.

Reinsert the SSD if the connection is loose or faulty. Additionally, check for damaged or broken motherboard ports or connections that might be causing the problem.

Other Possible Causes and Solutions

If the SSD is still not detected in the BIOS, consider the following:

BIOS Settings: Ensure that your BIOS is set to either SATA or NVMe controller mode. Secure Boot settings might also affect SSD detection. Upgrade BIOS: Check the OEM support portal for any BIOS updates that might resolve the issue. Some manufacturers release updates to support new hardware. Physical Inspection: Inspect the motherboard and SSD connections for any misaligned, bent, or damaged pins. Faulty connections or cables can cause the SSD to not be detected.

Conclusion

The BIOS is a critical component in your system that manages the interaction between your computer's hardware and software. If the BIOS does not detect an SSD or HDD, it can lead to various issues, including drive not spinning up or incorrect drive settings.

Following the steps outlined in this guide should help you resolve the issue and ensure proper detection of your SSD or HDD. If the problem persists, consulting the manufacturer's documentation or seeking professional help is recommended.
