Thanks for the suggestions. I would love to give both a try, but the card doesn't even show up on the phone or on my laptop. They both act as if there isn't even a card there.

My phone will make a beep when I insert the card, but it doesn't appear in file explorer.

They're much cheaper now than they were when I bought this one, and this one is still under warranty but I no longer have the receipt, so I'll just have to go buy another. Oh well.....
