The drive fails to reach full speed quickly enough, causing BitLocker to time out.

Symptoms

Possible Causes
  • Motor failure
  • Power supply issue
  • Cold environment

Step-by-Step Fix

1

Check Power Adapter

Ensure the drive is getting enough current to spin up.

2

Warm Up Laptop

If the laptop was in a cold car, let it reach room temp.

3

Replace Drive

Spin-up retries are a sign of imminent motor failure.

When to See a Technician

If a drive struggles to spin up, it is physically failing. Backup data immediately and do not attempt encryption.
