Laptop BitLocker failing on drive with system volume information fragmentation

4.5

Fragmented System Restore points block BitLocker from accessing the shadow copy area.

Symptoms
  • Encryption stalls at 90%
  • Error 0x8031005b
  • System Restore fails
Possible Causes
  • Too many restore points
  • Disk errors

Step-by-Step Fix

1

Delete Old Restore Points

Use Disk Cleanup > Clean up system files > More Options > System Restore.

2

Disable System Protection

Temporarily turn off protection to clear the folder.

3

Run chkdsk

Verify the integrity of the System Volume Information folder.

When to See a Technician

This folder is highly protected; if it's corrupted, BitLocker will struggle to secure it.
