Mechanical Hard Drive: file-system corruption. Directory and allocation records no longer agree after interruption or media errors.

The distinguishing clue

The volume asks to be formatted, mounts read-only or loses folders.

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: Image important data first and inspect the file system without writing to it. If confirmed: Repair from a copy or recover files before recreating the volume.

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.
