How to repair hard disk not detected

If your hard drive isn’t being detected, it can be due to various reasons ranging from hardware issues to software misconfigurations. Here’s a comprehensive guide to help you troubleshoot and resolve the problem.

1. Check Physical Connections

Internal Drives:

Power and Data Cables: Ensure that the SATA or IDE cables are securely connected to both the motherboard and the hard drive. A loose connection can prevent the drive from being recognized.

Alternative Ports: Try connecting the hard drive to a different SATA port on the motherboard. Sometimes, specific ports may be disabled or malfunctioning.

External Drives:

USB Ports: Connect the external hard drive to different USB ports on your computer. Preferably, use ports directly on the motherboard rather than front-panel or hub connections.

Cables: Test the drive with a different USB cable to rule out cable issues.

Power Supply: For external drives that require external power, ensure the power adapter is functioning correctly.

2. Verify BIOS/UEFI Settings

Access BIOS/UEFI: Restart your computer and enter the BIOS/UEFI settings (commonly by pressing Del, F2. or F10 during startup).Reddit

Detect Drives: Check if the hard drive is listed among the connected devices. If not, it might indicate a hardware issue.

Enable Ports: Ensure that the SATA or USB ports are enabled in the BIOS settings.Reddit

Boot Order: Confirm that the hard drive is set in the correct boot order, especially if it’s the primary drive.
