Observed condition
The drive arrived after being opened by a general computer repair shop. Several top-cover screws were missing.
Why this matters
Modern hard drives operate with extremely small tolerances. Dust, fingerprints, incorrect screw torque and uncontrolled head movement can damage platters or alter alignment.
Correct response
Power should remain off. The device should be assessed by a specialist with controlled opening procedures, compatible donor parts and imaging equipment.
Customer guidance
General repair shops are appropriate for many computer faults, but physical hard-drive intervention should be referred directly to a data recovery laboratory.
