I've had the same problem. My sd card is randomly unmounting .Tryed clearing the cache...no improvement. Shutting the phone off and removing the card, rebooting then shut off and reinsert the card, restores the card only to have it unmount again. Frustrating! This is tied to the security update from 12/28.
