I had a screw fall out after my hdd upgrade (DIY I might add so not Empeg's fault). It was one of the screws I had put in. Luckily it didn't affect the player at all but I immediately dismantled it and put the screw back in. I didn't have any Loctite to hand at the time so it might be unscrewing itself at this very moment. Thanks for reminding me. I think I'll do that now.
