hmmmm ok this happened after an update on my ROG Ally:

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 is a 512 GB card... i tried rebooting and reseating it. nothing. i can't even tell if the card is dead or just has a brkoen file system... what should i try first?
im comfortable following steps in a terminal if someone epxlains them, im just not sure where to start, and I dont wanna make things worse.
id also love to know how to avoid this in the future 🤦 is it the card, teh device, or just bad luck?? im about to throw this thing out the window lol
