SATA Solid-State 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

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

Related cause to rule out

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

Checks after the work

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