OK so I got another card at Fry's. This one was formatted and now the OS
doesn't even see it when it gets plugged in. Same story with 8.10. It's still
working fine in the camera. Any suggestions? Maybe start a new post since this
seems to be a different issue?

The other card is being shelved till I get this issue resolved. I don't have XP
installed any of my computers, so I don't really want to go there, but if I have
to, I guess I will.
