Symptoms
The EOL flag may be set on some SSD drives after they have been powered on for over 6.8 years.
Cause
The drive vendor has confirmed that the drive SMART POH is a 4-byte counter. It counts the number of 50-millisecond clock ticks since manufacturing for which the drive is powered on. This counter wrapped due to the drive being powered on for ~59,652 hours, or ~6.8 years.When the Power on Hours (POH) counter wraps, it resets to zero and starts to increment again. The wear level of the drive is unaffected. This results in the calculated days remaining to reach EOL for any drive with a wear level >25% to become ZERO. This results in the EOL flag to be set to TRUE for the drive.The following TLAs are affected per analysis performed by Hardware Engineering.
