Hi - When I insert a gaming or music disk into my PS3 it makes a noise as if it wants to eject the disk again. This either happens or otherwise it wont recognize that a disk has been inserted. This problem has just start happening. I have recently taken my PS3 to a mates place and back home again. Could transporting it have caused this problem? Hope you can help. Luke

Hello, It's possibly lens calibration problem, sometimes that happens when there's a lot of sudden movements during transportation, sometimes the use of scratched disks tend to trigger the Error correction algorithm of the PS3 reader, putting the reading lens into a lot of stress that heats up the EC chip and games are not read properly, causing the game to fail loading and making unusual sounds.
I recommend not to use scratched disks, try to use only PS3 game disks only to extend your console's life, and take good care of all your disks, keep them clean.
The thing is as technology improves Disks format changes to put more information into a single disk, and precision looking for data is more critical as data sectors are closer to each other, so scratched or dirty media tends to return errors.
Hope I helped, and try to seek some professional help on calibrating/substituting your old reader.
