I clicked on an MP3 on my media card to play and it popped up an error saying I needed to disable mass storage mode before I could play media files. I did so and was then able to play. I reenabled mass storage mode while it was playing and nothing bad happened.

After a reboot, it seems again to be able to play media files while mass storage is enabled.

My question is was this just a random problem, or the first signs of a problem with the media card?

Thanks.
