Suddenly yesterday afternoon my microSD card stopped working. It wasn't read by all my pc, except Chromebook (there was everything okay, but I will say more about that later).
On all my Windows machines I couldn't prepare this card to use, administrative Windows tools didn't work, even diskpart. It couldn't be successfully formatted, the letter couldn't be assigned, and the card was invisible in the system files explorer.
Only on Chromebook i could format this card and save/read files to/from there, it works fine, but not when I plugged it into a Windows machine. I don't have there important data, so I can do everything with it, but that card has a big capacity, so it is useful sometimes.
