    I'm having an issue with a particular USB drive and my Macbook Pro. This thumb drive will work on two other Mac Mini's I have. I can formate and use it with them. But when I plug it in to my Macbook Pro it won't show up any where. Can't even see it in Disk Utility. I can use other thumb drives with my Macbook Pro. Has anyone ever heard of something like this? Very weird.

    Sometimes, it's just that particular thumb drive.

    Do you have others that behave the same way?

    No, the others work fine. But his one used to work?
