    Thank you for your response. I tried what you said, went to device manager, and highlighted the computer icon, then scan for hardware devices, but it could not find it. My DVD/CD rom letters are still missing.

    If you know of any other solutions please let me know and I will try it.

    Again, thanks for your response.

    Thank you for your response. First I like to tell you that I am using Win. Vista, I tried to follow up what you said above but I had difficulty, maybe you are reffering to win. XP. Anyway, that does not matter I was just trying to learn.

    Last night I put the laptop to "sleep", not fully turned off, and after a few hours I was when I clicked on my computer icon (looking for something else), I realized that the drive letter is back and DVD/CD rom is working fine. I don't have an explanation for this!!!! it disappeared and suddently it came back!!!

    Anyway, thank you again for your help,

    best wishes,

DVD/CD don't work any more, not recognized by the computer. Driver is missing? Windows Vista


Try to go this website, click registry tweaks and on the Tech domain registry look for Restore missing CD drive. Just run it and allow. After that restart the laptop. Check if CD/DVD drive is back and test a disc.

Hope it works!

My computer could not recognize cd/ dvd drive. No drive letter or anything.Tried everything but still nothing happened. My driver is working (there is light bleeping) but when i insert a cd, no action....

I had the same issue, not once but twice. Both times however, it required service technicians to fix, and actually replace the device. There was an additional issue however that may have started the decline in the first place. I am unable to get high speed internet, and as a result, many of my updates are interrupted and files slowly become corrupted. If this occurs often enough, it can actually corrupt your O.S. and browser! I had to replace the internal CD/DVD in my computer twice, and the last time, they had to wipe my computer and reinstall the O.S. Not the best of news. What I do now to avoid the problem, is to disable automatic updates, and only update elsewhere where I can get high speed internet services. It's a pain, but better than having the issues that come with slow internet. .

CD-R/DVD Drive with "missing or corrupted driver"

You might be best off to take your computer back in time.

Start > Help and Support > Undo changes made to my computer > Restore my computer to an earlier time > Pick a date at which time the cd was working properly. This will fix the driver problem..

Please let me know if this works for you, or if you have problems doing it.

CD/DVD letter missing? tried restore. worked before but not this time... Somebody offered a solution (below) BUT _________ Highlight by clicking on "UpperFilter" and "LowerFilter" ONLY - then hit Delete on...

I just wanted to post a reply regarding a missing dvd/cd in the ?My Computer? & in the ?Device Manager?. I bought my Acer5610z in September of 2007, about March of 2008 I was unable to use my dvd/cd because it was not being recognized by the computer. This was very frusterating as I like to back up files often. I have tried EVERYTHING! 1)I have tried to mess with the registry as suggested by several sites.. NOTHING 2)I have tried to uninstall any applications which would mess with my player such as ITunes..etc.. NOTHING 3)I would have tried to restore my settings back to factory default but I cannot remember my freaking password for erecovery.. So this was not, nor is it still an option for me. (Anyone who reads this and knows a lil trick for me to fix that issue please feel free to let me know. thanks.. Anyways.. I found this website and got very excited because I seen all the great comments and thought to myself, now maybe after about a year (give or take)I might be able to burn cds again! You will never guess how I fixed this issue!!! *I first took out several screws on the back of my laptop..scared I was gonna mess up my comp.. but didn?t.. whew.. For the life of me I could not find a way to access the dvd disk drive to ensure things were plugged in properly. (I never messed with a laptop yet) I couldn?t find it.. Then my lover found a site online which detailed how to remove the dvd/cd drive to ensure it is plugged in all the way, sound scary? meh.. Turns out all you have to do is eject the disk (use paperclip into hole) and you can gently pull on the metal that you see holding the edge of the dvd player. Pull it all the way out (its a plug n play so don?t worry about cords)on my Aspire 5610z anyways CHECK YOUR SYSTEM DETAILS TO ENSURE IT DOES NOT COME WITH CORDS) Replace the dvd/cd back into the slot and press firmly but not too firm to break it (you want to make sure its plugged in all the way) Reboot.. Voiiiiiila! xoxox Hope this helps someone out there and if so spread the news.. I looked forever for this stupidly simple alternative to messing with the registry etc..

You need to boot with your windows vista cd and select repair install. This will reinstall the windows files, including the ntldr file, leaving your data intact. Make sure you only do the repair install, if you do the full install, it may wipe your data.

Thanks and please take a moment to rate as fixya.

Optiarc cd-rw crx880a ata device: This device cannot start. (Code 10)

Did you try to click "Troubleshoot" on the page that reported "cannot start" ?

Did you try to click on the device, and choose "uninstall" ?
Then, rebooting Windows should cause Windows to "find new hardware", and properly configure the DVD/CD drive.

Code 39 for dvd drive

You can solve this problem by going to start, then run, type regedit. open hkey_local_machine, then system, then control, then class, then 4D36E965-E325-11CE-BFC1-08002BE10318, once in this go over to the right hand side and delete upper filters and then lower filters. restart your computer and your dvd/cd-rom drive will work properly, if you look in device manager there will no longer be a question mark and it will tell you all is working correctly.
