Laptop BitLocker failing on drive with pending sector reallocations
4.5
The drive has "weak" sectors that it's waiting to remap, causing encryption hangs.
Symptoms
- Slow encryption
- Disk usage 100%
- Error code
Possible Causes
- Failing disk
- Unstable sectors
Step-by-Step Fix
1
Force Reallocation
Perform a full format (not quick) to force the drive to remap sectors.
2
Check SMART Attribute 197
Monitor the "Current Pending Sector Count".
3
Clone to New Drive
Move data to a healthy SSD before it fails completely.
When to See a Technician
Pending sectors are a major red flag; the drive is actively failing and should not be trusted with encryption.
