hmmmm ok okay, I'm worried. My Switch OLED worked fine with my microSD card from my old phone until since I took the card out to use in a PC. Now:

microSD card can't be read
The card may need to be formatted for this system,
or it may be damaged. Formatting erases all data.
Card: 512 GB - status: not mounted
The card shows up fine on my laptop, at least teh folders do... i haven't formatted anything yet. What should i check before i hit that button?
Id rather not lose my screenshots and videos if theres any way to save them. The games I can download again, but the memories are another story.
I'm not in a rush, but I'd like to buy the right thing next time. If anyone can explain what to look for in a card, that would help a lot.
