Brand new sd card: Android says corrupt, works in Windows

I have an LG G6 and just bought a Samsung 256GB microSD. I copied everything from my old card onto my PC, then onto my new card, and put in my new card, and Android says it's corrupt and needs formatted. I try to format it and it always gives an error saying the command failed. Put it back in my PC (which now can't use the card either) and performed a format (without the Fast option). But it still won't work -- Android just says it's corrupt and always fails to format it. Any ideas?
