Laptop BitLocker failing on drive with VSS service disk I/O spike

4.5

VSS creates massive disk traffic, causing BitLocker to time out.

Symptoms
  • Disk usage 100%
  • System lag
  • BitLocker error
Possible Causes
  • Large shadow copy creation
  • Slow HDD

Step-by-Step Fix

1

Limit Shadow Storage

Reduce the max size of shadow storage.

2

Use SSD

SSDs handle the high I/O of VSS much better.

3

Schedule Encryption

Start encryption when the laptop is not being used.

When to See a Technician

VSS I/O spikes are normal but can overwhelm older mechanical hard drives.
