Nu cdrw/dvd dbw-521 draw opens and closes repeatedly

The draw of my cdrw/dvd keeps opening and closing. I use the close button when I operate the device but it seems not to want to synchronize the drawer with reading the cd/dvd

    No I don't have a virus. Is seems more like a mechanical fault because if I hold the tray momentarily whilst it is trying to close sometimes it will line up and behave for a while.

This sounds mostly like you got a Virus in your system, please make sure you got a good one like or Antispyware....

If you are familiar with windows services and startup Items you can find the one that is infected.

    IF that is the case then the only reason could be that the EJECT button is having a malfunction, then it should be corrected cleaning the part with a good Di-Electric Spray that can wipe out the grease from the area, else try replacing the Drive, (there are many cheap ones) if you still experience this problem after replacing the drive then YOU HAVE a VIRUS FOR SURE

I have a HP PC and the DVD CD Rom keeps opening and closing by it self. How can I fix it?

First, with the power off, open the computer case and disconnect the 4-pin power plug from the drive. Then at least the drive won't open and close while you try to figure out what's wrong.

One possibility is that the front panel open/close button on the drive is sticking. Then the drive thinks you're always pressing the button. In that case, replace the drive. New DVD/CD burner drives are only $30 or so, so it isn't worth repairing one. I think you'll probably find the drive is just faulty.

Another possibility is that your computer has a virus. Random drive opening and closing was caused by a virus going around a while ago. I don't remember the virus name, but it was quite a while ago. Still, it's worth checking unless you're absolutely sure you have up-to-date antivirus software and you've been scanning your computer regularly. I would suggest downloading the free version of MalwareBytes' Anti-Malware and doing a complete scan to see if it finds anything. If it does, let it correct the problem.

If it turns out to be a virus problem, don't forget to plug the power connector back into the CD drive when you've cleared the trouble.

Hope this helps, and thanks for using Fixya!

Cd drive has disk in it and wont open

Look closely on the face plate and around the face plate of the CD drive. (better to have good flash light/Torch while doing this). Close to the eject button (Or around that area) there will be a very small hole (pin hole). Switch off your computer if it is powered. Push a needle or a safety pin into this hole. Take care to push it in straight (not angled). If it does not open in the first attempt repeat changing the angle slightly. May take 3 or 4 tries. But you can definitely get it opened.

Dvd/cd drive door keeps opening and closing by itself

If the trouble isn't being caused by some screwy virus or software problem, the best solution is to replace the drive. New drives are quite inexpensive and widely available in retail stores (at higher prices) and online.

CD/DVD drive stuck CLOSED and NO pin hole

Use my computer and select the drive (eg drive E:). From pull down menu "File" select "eject". While the disk door attempts to open (hear slight movement of tray) massage the door with your fingers. This is done by smoothing out the across front door panel with your finger tips and pushing in and releasing pressure from door. Door should slide open partially and close again. Repeat. The eject button nearside the disc tray doesn't seem to work as well as selecting "File" and "Eject" from the menu. Something to do with the door cycle is less with the direct eject button.

Hmmm... my cd rom driver is not working well. i cannot open and play a cd. i dont know how to fix my aplication. how can i fix my problem?

Should be a tiny hole in the front just below the cd drawer (make sure its not the indicator light hole)

Insert a paper clip or thin piece of wire (about the same diameter as the hole) into this hole and you should feel a solid piece maybe 1/2 to 3/4 inch in. Push firmly on the wire and the cd cdrawer should open out a bit. Gently pull it further and remove the cd.
Reboot your pc with the drawer left out - it should close by itself - if it closes OK then try opening it with the front button. If that works try another cd in it. ANy drams with get just get a new dvd/cd player or burner as the cd player is not worth repairing or replacing due to the cheap cost of dvd player/burners.

If it closes ok then try opening it with the button -

Can this be fixed??

I'm assuming you've tried multiple CD's, DVD's, audio discs, etc with the same results... at this point, you're probably looking at a bad drive (something wrong with the electronics that's telling the computer to "eject" instead of "load") ....however, here's a trick I did once to fix this problem:

Close the CD tray, and just as it's closing, hold on to it and keep it from closing ...again, the drive's probably bad, so you're not going to hurt it...the drive will fight you for a moment, then open back up. Now try closing it again (with the button) and see if it stays this time.

If so, woo-hoo! If not, time to head to the store :)

Hope this helps - remember to rate :)

My cd/dvd opens then closes

> I've already replaced it once

Well, I've seen CD-drives that would re-open, when you try to close them -- it is _falsely_ detecting a "jam" as the tray is closing, and then just re-opens the tray, rather than "forcing" itself to close.

Replacing the CD-drive is the only way to fix that type of "false-positive" jam-detection conditions.

But, since you've done that, either you were unlucky-enough that the replacement drive was also "defective", or, you have a computer-virus on your computer that is maliciously issuing commands to the CD to "open-the-tray".
