I have found a paper clip is too soft, as you have to push quite hard for the drawyer to pop out, which is only a little way anyway. Thus a paperclip tends to bend.
Something like a blunt sewing needle should work.
You have not advised make, model, desktop or laptop.
If no luck with the needle, you will have to remove the drive from the pc and remove its top cover. Then you can then can see what is happening (maybe 2 cd's?) and manually push the drawyer release lever.
Please advise back on progress.
Good Luck - Keep us posted.
