Mechanical Hard Drive: interrupted write or unsafe removal. Power or connection is lost before cached data reaches the media.

The distinguishing clue

The problem begins immediately after unplugging or a sudden shutdown.

Checks before an assessment

If unusual clicking or scraping is already audible, stop repeated startup attempts. Do not open the drive or run a benchmark to obtain another recording.

Stop point: Opening a hard drive outside a controlled clean environment destroys recovery chances.

Workshop confirmation and repair

Device-level check: Listen once, inspect health information if safely available and prioritise data recovery over benchmarks.

Targeted check: Avoid further writes and compare file-system state with recent backups. If confirmed: Recover or repair data, then verify safe-eject and power behaviour.

Repair boundary: Recover important data first and replace the drive when mechanical failure is confirmed.

Related cause to rule out

When performance starts normally and falls or disconnects after sustained transfer, also consider Mechanical Hard Drive: storage thermal instability before choosing a repair.

Checks after the work

After repair or replacement, check verified file access on the replacement, health status and backup operation.
