Mechanical Hard Drive: storage thermal instability. The controller becomes unreliable or slows sharply when hot.

The distinguishing clue

Performance starts normally and falls or disconnects after sustained transfer.

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: Log temperature and transfer behaviour with adequate airflow. If confirmed: Correct cooling or replace the heat-sensitive drive after data is secured.

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

Related cause to rule out

When the device hangs at detection or fails after sleep despite acceptable media health, also consider Mechanical Hard Drive: drive firmware fault before choosing a repair.

Checks after the work

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