We have raspberry-pi based IoT devices on field. We face an issue sometimes of SD card dying out after long usage of more than 2-3 years.
The datasheet for card WD Purple QD101 mentions SMART card health monitoring capabilities.
I am sure this will be possible from the WD software in windows but we want to monitor the health from the raspberry pi itself.
Is it possible to use the SMART capabilities of this SD card in a debian/linux based OS ?
We tried using smartmontools command line utility but it was unable to detect the device type.
