Mechanical Hard Drive: storage controller failure. The electronics translating host commands to the media stop responding correctly.

The distinguishing clue

The drive vanishes, identifies incorrectly or freezes the bus.

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: Choose a data-preserving inspection from the drive condition and the value of its files, without repeated startup or stress tests.

Targeted check: Compare another port or enclosure and inspect identification and power behaviour. If confirmed: Recover data through the safest path and replace the failed controller assembly or drive.

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

Related cause to rule out

When health warnings, read retries or increasing bad blocks appear, also consider Mechanical Hard Drive: worn storage media before choosing a repair.

Checks after the work

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