Laptop unable to use BitLocker on drive with load-cycle count limit
4.5
The HDD heads have been parked and unparked too many times, wearing out the ramp.
Symptoms
- Clicking
- System hang
- SMART warning
Possible Causes
- Aggressive APM settings
- Linux/Mac OS behavior
Step-by-Step Fix
1
Check SMART Attribute 193
Monitor "Load Cycle Count".
2
Adjust APM
Use a tool like QuietHDD to stop frequent parking.
3
Replace Drive
If the count is over 600,000, the drive is near failure.
When to See a Technician
Many laptop drives park their heads every few seconds to save power; this can kill a drive in 1-2 years.
