I have a HP 'puter with a 'Tower' ,. One CD/DVD disk drawer would not open when button was pushed. Go to 'COMPUTER' and click on it and a selection of various drives will appear on your 'puter. EXP~~ A drive, B drive, C drive etc etc. Determine which drive icon will not slide out and RIGHT click on the icon. A box drops down . Select 'EJECT' and it should open with ease.
