Media Wearout Indicator - WD Blue SSD - incorrect value - firmware error

Is there someone from WD who is able finally to confirm why the WD Blue SSD counts Wearout differently than all producers?


Model Family:     WD Blue / Red / Green SSDs
Device Model:     WDC  WDS400T2B0A-00SM50
Serial Number:    1926D7420114
LU WWN Device Id: 5 001b44 4a8e02f24
Firmware Version: 411030WD

the drive firmware counts it in the opposite way:

  • wrong (as is): value 001 means 1% of the wearing, then it remains 99% of the lifespan.
  • correct: value 001 means 99% of the wearing, then it remains 1% of the lifespan.

This causes problems for systems that control health checks via smartctl, including ID-230, which is about the Media Wearout Indicator. Especially for almost new drives, which status is perfect (rest of indicators), except Media Wearout Indicator = 001 = what is wrong. The correct value should be 099.

Is it possible to change it by a firmware upgrade/downgrade?
