Contact Dell EMC Support if you have any issues or failures.
If the drive has already failed due to this issue or additional help is required, please contact Dell EMC Support.
Once the D417 firmware is applied to an online and healthy drive, the drive is no longer at risk of failure at approximately
40,000 Power On Hours. If a drive is already in a failed state, it will need to be replaced. If you have experienced DU/DL
(Data Unavailable/Data Loss), contact Dell EMC Support. This recovery process will not restore the data on the drive
that is already lost.
