I get the problem on my PS4 after playing Battlefield 4 all the time. I remove the disk and hear the same thing as described here, the eject mechanism spinning, then turning it off and hearing continuous two beeps. Oddly, it doesn't stop beeping after unplugging it. I have to remove the HDMI and ethernet cable to make it stop.
I may be wrong, but there seems to be a bug in Battfiled 4 that is causing this. Either that or a player in a game has a hack running that kicks it off. I never have trouble with need for speed, which is a real PS4 disk. The BF4 is a PS3 game cross platform deal.
For 3 weeks. Then I installed 1.60 and boom it came back. But this time I was playing Lego Marvel and the disc popped out. This is with rubber feet off and vertical and having rebuilt db 2x and updated firmware to 1.52 via safe mode (despite it being already 1.52). Just applying 1.60 brought the issue back.
It is beginning to seem like a firmware issue and could be something to do with heat.
Whatever it is it is very annoying.
What makes me really sad about this, is the fact that Sony didn't say a word about this bug and about all of the bizarre bugs that is happening with PS4. Searching on the internet about what people want on the next firmware update, I found everything, except the correction of this annoying bug! This bug is bizarre! How could people claim for headphone compatibility, folders, more apps, etc. instead of having this and other bugs corrected?! I just can't understand... How could these cosmetic things could be a priority instead of the PS4 stability?!
Anyway, I did the update do 1.6 and so far so good.
This is a topic about the bug of the ejection of discs. I have another problem that was not resolved by this firmware update. I just can't save my progress on FIFA 14 and everytime I try to save, I recieve the CE-34878-0 message. But this is for another topic.
The problem of ejecting disc didn't happen so far. I played FIFA 14 for an hour and everything (except the saving problem) was ok. Let's see if the problem will not happen anymore.
PS: Sorry for my bad english. I speak Portuguese.
Since I have my set vertical I now don't think it is an issue of heat triggering the eject button plus the eject button should not prevent discs from being inserted.
I believe it is some internal thermostat problem causing the disc to be ejected for safety reasons like prevent damage to the disc due to high internal heat. I don't know the safe temp ranges for BD discs but it could also not be actual temp but rather rate of temp increase?
On the PC side of things motherboards have similar features which force a hard shutdown if temps go too high eg 70C/160F.
