I tried to burn a cd, but the optical drive did not recognize the disc, and did not eject it. Now it is impossible to remove the disc from the drive. I several times switched the system on and off. No result. Please help. Thanks.
Restart and hold the mouse button down to eject a disk. There are a lot more remedies if you need them, just ask.
Mac or PC? Update On a Mac you have to open Terminal the Type DF the you will have a list of the drives in your mac then type : diskutil eject [the name of the CD, usually the last name on the list] and then it should be out, if you are using windows I do not know the solution…
