micro sd card can't format by pc

[Nuclear Boy]

Try using 3rd party partitioning tool... It could be a filesystem that isn't supported by Windows (which I assume you're using)

Like if I were to format my card to Linux's ext4 or btrfs, they won't show up either in Windows.

If that doesn't work, then it means your SD card is most likely kaput.

I also have a thumbdrive, suspected to be kept in a high humidity room and now it spoilt. Cant read it, cant format it

Ya my dashcam sandisk micro sd oso spoil recently. I bought a new endurance sandisk micro sd. Its quite expensive compared to normal one. Hopefully can last.

the annoying part is it can die suddenly

Mine slowly die. Always ask me to format.
