Windows 7: Cd-drive does not eject

Hi !
I have Acer 4810TG. If I start computer (turn power on) and press cd drive eject button then it opens. If windows is loaded then it doesn't eject anymore. cd drive ejects when I open MyComputer - Cd Drive - Right Click - Eject. But with button It does nothing. I reinstalled windows 7 ultimate 32bit and still same problem. Need help ...

Welcome!

Try upgrading the firmware on your drive. You can also try updating the drivers for it in Device Manager.

Good luck,

tnx for fast reply. I'll try that.

Well, driver software for my device is up to date. I can't find firmware. Device is HL-DT-ST DVDRAM GU10N ATA Device

Try here

The Firmware Page • Index page

Are there more any other solutions to suggest ? Firmware upgrade seems to be hard work :P cd Drive worked fine with windows vista. If not then I still try to upgrade. What if I install windows 7 64bit ?

Well you can try running a system files check. Open an elevated command prompt and enter sfc /scannow.

I forget to say that if i press eject button then hdd lights goes on for few sec. Scanning right now.

scan is complete. Windows Resource Protection did not find any integrity violations.

Well, in that firmware page they answered ''I do not think this is a firmware problem''. Installing Windows 7 64bit right now, mby it helps. Any other suggestions ?

I noticed now that if i push few times eject button then cd drive dissapears from My computer and from Device Manager too. It seems windows thinks that eject button is cd drive power off button :P. With 64bit problem stays.

Could it be registry issue ?
I made this
Another thing to try would be to disable the driver signing permanently by disabling the integrity checks flag. To do this follow these instructions:

1. Click on Start > All Programs > Accessories > Right click Command Prompt > Run as administrator.
2. Paste the following line into the Command Prompt window and hit Enter
   
   bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
3. Restart the computer.

After that this is not happening anymore. but still cd drive is not opening by button. ''I noticed now that if i push few times eject button then cd drive dissapears from My computer and from Device Manager too.''

PROBLEM SOLVED BY INSTALLING OpticalDrive PM Application!!!

Thank u all who tried to help !!!

Thank you for posting your solution. Glad it's working now.

How come you forgot the Acer Optical Drive PM Application...?

It is a manufacturer apps install since the beginning, surely you must have uninstall it!

By the way, if you want to know the DVD Burner firmware version, you should open the device manager (screenshot), then scroll the list for hardware ID (Drive_____xxxx___):
