SATA Solid-State Drive: worn storage media. Worn flash cells can no longer retain data reliably.

The distinguishing clue

Health warnings, read retries or increasing bad blocks appear.

Checks before an assessment

Note whether the drive vanishes or remains visible but reads slowly. Protect files before attempting fixes that write to the drive.

Stop point: Do not keep power-cycling a drive that is dropping offline.

Workshop confirmation and repair

Device-level check: Compare cables and ports, inspect health data and protect files before stress testing.

Targeted check: Read health data and prioritise copying important files over stress tests. If confirmed: Replace the worn device after recovering or cloning readable data.

Repair boundary: Replace the confirmed drive or repair its data or power connection after cloning recoverable data.

Related cause to rule out

When the drive vanishes, identifies incorrectly or freezes the bus, also consider SATA Solid-State Drive: storage controller failure before choosing a repair.

Checks after the work

After repair or replacement, check startup, file copy, health data, restart and sustained idle.
