Laptop BitLocker failing on drive with shock detection

4.5

A sudden bump or movement triggers the drive's safety mechanism, interrupting encryption.

Symptoms
  • Immediate error
  • Process cancels
  • Clicking sound
Possible Causes
  • Moving the laptop
  • Bumping the desk
  • Faulty accelerometer

Step-by-Step Fix

1

Keep Laptop Still

Do not move the laptop while encryption is active.

2

Disable "Free Fall Sensor"

Temporarily disable the sensor in Device Manager (Risky).

3

Check for Physical Damage

Ensure the shock didn't cause a head crash.

When to See a Technician

The "Free Fall Sensor" parks the HDD heads to prevent damage, but this also kills any active write operations like encryption.
