Hi, 

I am using STM32l432kc board with sd card module. I have 16gb class 10 sd card.  I have used cubemx ide for coding and configuration purpose. I am using @https://microcontrollerslab.com/microsd-card-module-stm32-blue-pill-stm32cubeide/ and also seen various tutorials on youtube. still i am not able read or write on sd card. Please note that i am using SPI protocol. I got FR_OK for mount but for find_volume, I get FR_NOT_READY. 

can anybody have successfully interface them before? Please help in this regards.

    You may refer to microSD application projects based on STM32L496G-Discovery and STM32L476G-EVAL. Both boards are different than your board from hardware point of view, but I suppose there are some similar points: STM32L4 and SD and FatFs.
