Prusa is not recognizing my SD card. What to do?

Hey guys, My Prusa MK3 is not recognizing the SD card. That is the first message I see when it boots up. SD card is not corrupt since i checked with my laptop. How do i fix it?

There is a size limitation - perhaps your card capacity is too large?  Try a different SD - small capacity ones work the best since you really can't select effectively if the SD card has many many files on it anyway.

I don't think that is an SD card error message.  I seem to recall that languages are stored in the boards external flash.  If its having issues accessing the external flash then I would expect something like that.

I'd try reflashing the board.

I was actually trying to connect adafruit feather to Prusa board and the adafruit MCU was burned. After that time, I started having this problem. So it could be that Prusa Circuit board is damaged. Doesn't look like a SD size problem. Do you guys think that its better to replace the PCB? I wonder if I can get a replacement from Prusa company.
