About the part that has "Added code to shut down the player automatically in the event of a disk problem (for example, if the player were dropped while accessing the disk). The player can be restarted as normal provided the disk has not been physically damaged."

What would be the result of the player not shutting down when there is a disk problem? My first Karma died whilst I was on the tube and I didn't have a long pin or wire handy to reset it so I had to leave it clicking trying to write the playlists before shutting down for over an hour.

By the time I got home, the entire Karma casing was quite warm. I was wondering if the lockup was the cause of the disk failure or just a symptom of it?
