If you`re talking about an internal optical drive thats in the case
- is it possible someone has jarred the drive`s tray when it was ejected, e.g. they ran into it
- sometimes the tray won`t eject if it`s screws holding it in the case have the drive positioned slightly askew.You could try opening up the case by removiing the left side panel as seen from the front, and loosening the screws that hold the optical drive on that side, re-positioning the drive a bit, and tightening them again, then try to eject the tray by pressing the button on the front of the drive. Repeat as many times as necessary.
- if the drive has been used a lot or is old, sometimes the drive belt just inside the front of the drive has broken, or is slipping on its pulleys. All optical drives have a tiny hole ìn front under the tray - if you push a stiff wire straight into the the hole, the tray lock will release, and you can then pull the tray out. If someone has run into the tray when it was open, you may be able to wiggle the tray from side to side or otherwise un-jam it by fiddling with it. You can often see the belt, intact or broken, when there is no disk on the tray, just inside the front of the drive. If the belt is broken or stretched and slipping, you can remove the drive from the case (unplug the computer before removing it`s power connector and data cable, and before you plug them back in). open up the drive by removing the top cover, and use an appropriate sized rubber band temporarily (e.g. get a bag of assorted sizes from a `dollar`store if you don`t have one handy) , or just replace the drive with another one - new drives are relatively cheap, especially if you get a `bulk` one - merely a drive in an anti-static plastic bag, rather than in a fancy box. You can test the tray when the drive`s out of the computer by connecting a power connector from the PS to it while the computer is not running and the case is unplugged, and while the computer is running, press the button on the front of it - the top cover doesn`t need to be on the drive.
- if you`ve tried re-positioning the drive, that did not help, and if the tray won`t unlock when you push a stiff wire through the tiny hole in the front of it, something is broken or loose or jammed inside of it. Remove the drive, open it up, and see what is broken or loose or jammed. If the button that holds down the top of the disk when it`s spinning has come loose, you can often glue it with epoxy glue, making sure it`s in the right position, making sure the glue has had time to set properly, then the drive will probably work fine after that. If something is broken, you`ll probably need to replace the drive.
