Sounds like your SD cards might be encrypted. Can you use them in a working phone and turn encryption off? Or you used them as internal storage (install apps on them), in which case you cannot read them I think.
That's a good idea. My current phone has an SD card, but I'd rather not remove it as I've got apps and stuff on it.
