Troubleshooting steps 1. Perform a hard reset (8. Hard reset on page 76). 2. Reset BIOS to default. 3. Verify storage device connection and flex cable. Reseat storage device and cable connection. For multiple storage devices, keep the primary drive with the operating system and remove other devices. 4. Use the HP Hardware Diagnostics tool to verify the drive is recognized and test it. 5. If the storage device fails diagnostics, record failure and have the drive replaced. 6. Identify when the issue is related to software. If the storage device passes diagnostics, test the drive on a verified working computer. If the failure follows the drive, reinstall the operating system to make sure software is not an issue. 7. Test with a verified working storage device. If it is still not recognized, the system board is faulty. NOTE: If the drive is seen in BIOS and Diagnostics, try a secure erase prior to replacing a drive as this may resolve related issues.
