I have a Memorex TwelveMAXX1032 cdrw which won't let me open the drawer and I have to use the manual 'pin' method. Neither pushing the eject button or software ejects work. However, both these methods work fine when the drive is empty.
It has to be software that is causing the problem. I suggest uninstalling Easy Cd Creator and any packet writing application that goes with it. If you can then eject the cd normally you will have proved that is the culprit. Reinstalling Easy Cd Creator may then still allow cd ejection. Otherwise I have found NTI CD-Maker from the Nov 2003 cover disk of PC Advisor mag to be quite good.
