What title were you trying to eject?
I was not trying to eject any disk. I was playing multiplayer Battlefield 4, while streaming on Twich.tv when the disk suddenly ejected, and continues to eject every 15 seconds or so even with no disk in the drive.
Were you installing any game data at the time?
Did you see any game or system notifications beforehand (Ready to install notifications, error messages, etc.)?
What troubleshooting steps did you attempt?
Reinstalling Battlefield 4, booting down my PS4, starting it up again.
While it functions the PS4 is an awesome gaming device, after these bugs are killed I'll be a happy camper!
Mine did the same thing. I did the vertical orientation trick, and that fixed the ability to insert discs, but the drive still wasn't spinning up and reading them.
I work up this morning to call Sony, brought the system out of standby, popped in a disc, and it started working! So, at least in my case, it looks like the hardware (theoretically) works - hopefully, there's a software issue causing the disc read/eject problems for at least some of us.
