Noisy hard drive IMPORTANT: An SSD has no moving parts, so it does not make loud or clicking noise. Depending on type and rotational speed, some hard drives will make more noise then others. Not all noises are related to the fan or hard drive. Items Symptoms ● Loud noise from hard drive ● Clicking noise from hard drive ● Still boots to operating system and operates normally Tips & tricks Procedures Possible causes BIOS, hard drive firmware, driver, faulty drive, power supply (AC adapter). Troubleshooting steps 1. Update BIOS and hard drive firmware. 2. Examine AC adapter to be sure that it is not faulty or overloaded. Disconnect all peripherals (USB storages, dock, etc.). 3. Remove hard drive to isolate the noise. 4. Test the hard drive on a verified working computer if the noise continues. If the hard drive makes the same noise or clicking sounds, the sounds are either normal sounds for the hard drive or a fault with the hard drive. 5. Verify original hard drive connection and flex cable. Reseat hard drive and connection. 6. Run HP PC Hardware Diagnostics (UEFI). If failed, record failure code and have the hard drive replaced. 7. If no error with HP PC Hardware Diagnostics (UEFI), perform disk defragmentation (some hard drives make a clicking noise when highly fragmented). For optimal system performance, place your operating system and all of your most commonly used applications and files on the fastest hard drive or solid-state drive and on the fastest areas on the drive (primary partition of 200 GB max).
