Problem with clicking sound from hard disk

If “hard disk clicking” occurs repeatedly, it is better to narrow it down to a mechanical drive head/motor problem, power source, or physical failure rather than changing several settings at once. Prioritize backing up important data, then check the actual drive status using SMART and manufacturer diagnostics.

  • Power or physical failure

How to solve

Please check them in order from the top. If the issue is resolved, you do not need to proceed to the next step.

1

Back up your important data immediately

Repeated recognition failures, SMART warnings, abnormal sounds, and freezing may be precursors of drive failure.

Difficulty Easy time as soon as possible cost 0 won
  1. 1Copy files that cannot be replaced, such as documents and photos, to another storage device.
  2. 2Large-capacity benchmarks or unnecessary write tests are performed after backup.

confirmation point

After these steps, see if the “hard disk clicking” symptom decreases or disappears. If there is no change, check for possible mechanical drive head/motor problems in the next step.

2

Check SMART and manufacturer diagnostics

You can check the status and error history reported by the drive.

Difficulty Moderate time 10~30 minutes cost 0 won
  1. 1Use the manufacturer SSD/HDD diagnostic tool or the trusted SMART verification tool.
  2. 2Check for warnings, bad sectors, media errors, and temperature abnormalities.
3

Rule out cable, port, and power issues

Especially with SATA and external drives, connection issues can also look like errors.

Difficulty Easy time 10-20 minutes cost 0 won
  1. 1Use a different SATA/USB cable and port.
  2. 2External drives connect directly without a hub.
  3. 3For products with a power adapter, check the power rating.
4

Perform a file system check after backing up.

Recovery tools like CHKDSK can be taxing on unstable drives because they change the file system.

Difficulty Moderate time 20 minutes or more cost 0 won
  1. 1Verify that the backup is complete.
  2. 2Run Windows Error Checking or CHKDSK if necessary.
  3. 3If additional errors occur during testing, stop using it and consider replacement/repair.
5

Replace drive if warning repeats

SMART warnings or physical abnormal sounds may not be resolved by software settings.

Difficulty Advanced time 30 minutes or more cost New storage cost
  1. 1Prepare a new drive.
  2. 2If possible, clone data or do a clean install when it is healthy.
  3. 3Do not use a suspected failed drive as the only storage location for important data.

Precautions

If you suspect a storage device error, back up important data before recovery. If there are SMART warnings or repeated recognition failures, it is safer to not continue using it.

The file is damaged and cannot be opened or an error occurs.

If you see “file corruption” symptoms, possible causes include storage device or file system errors, abnormal termination, etc. Prioritize backing up important data, then check the actual drive status using SMART and manufacturer diagnostics.

Disk usage skyrockets and the entire computer freezes

When troubleshooting a problem where disk usage is skyrocketing and the entire computer freezes, it is important to rule out the causes one at a time. Based on the “SSD 100% freezing” symptom, check the storage device response delay or malfunction and the storage driver before proceeding to the next step. Prioritize backing up important data, then check the actual drive status using SMART and manufacturer diagnostics.
