I have 2 SD cards (let's say card 1 and card 2) and they both worked until yesterday. But yesterday when I want to read recorded songs on card 2 using the RECORD screen, I get a question mark in top left corner followed by the other songs recorded on card 1. There is a search icon turning indefinitely.
But card 2 works normally if I backup my presets on it and it is recognized by the M20D in the SETUP screen where I can see its icon in the top left corner. Card 2 runs also normally on my PC.
How come? Thank you for your help
