I have a PNY Class 10 32GB microsd in my Droid 3, for some reason I am randomly losing media files. This has happened at least 3 or 4 times. I have formatted the card with both my pc then with the phone itself several times. The problem eventually comes back. I think it could have to do with random reboots that occur as well but not 100% sure on that part. Has anyone else had this happen to them? If so, what if anything did you do to resolve it.
