my cd/dvd drive recently quit reading. the previous day it worked fine. it first thought it may be a spyware/malware problem but that all looks ok. i did clean it with compressed air and still not working. the drive attempts to read the cd/dvd but just wont.

any thoughts?

Hello,
Let's have you uninstall the DVD-Drive and then have you reboot and let windows reinstall the drivers for it. To do this, do the following:

• Go to START-->RUN and type devmgmt.msc
• In the new window that appears, click the + symbol next to CD/DVD-ROM Drives.
• Locate the drive in question and right-click it and choose UNINSTALL.
• Once it's finishing uninstalling, reboot your computer.

Once it's rebooted, try putting a DVD in it again and see if the same thing happens.

----------------------------

If after rebooting you are still having problems, try the following:

Click Start then Run and type regedit...click "Ok"

In the left pane, expand (click +) HKEY_LOCAL_MACHINE, then SYSTEM, then CurrentControlSet, then Control, then Class, and click on {4D36E965-E325-11CE-BFC1-08002BE10318}

Right click on {4D36E965-E325-11CE-BFC1-08002BE10318} and choose Export. Name this file "filters" and save it to your desktop. This file can be deleted when it is determined it is no longer needed.

In the right pane, if either UpperFilters or LowerFilters are present, right click on it and choose Delete...accept the deletion. Delete both if they are both present.

Close Registry Editor and reboot.

----------------------------

If after doing that your drive still doesn't show up, please download CDGone from HERE. Once it's downloaded, extract the files to your desktop and open the READ ME FIRST.TXT file and follow the instructions there.

Post back with how things are going after doing the above.

i did everything except running the cdgone. i was prompted to answer what file type when i tried to open the edit.reg.reg

i did call "tech support" with the company that has the warranty. they said the drive is faulty and needs to be replaced but i need to sent back the laptop. what bothers me is they can't guarantee any software loss. they said they will check all hardware and if anything else needed replaced they would do it also .. if the hard drive has a problem it would be replaced but no data migration to the new hard drive. going out to buy an external drive and copy the entire computer to is later today.

thanks

hello edi006,

so what HFCG suggested didn't work? then it's possible it's the drive itself failing.

and you probably test the drive with another media i suppose. wait, have you tried reseating it by the way?

speaking of warranty, what kind of warranty do you have? if it's within warranty and you are certain that it's just the optical drive that needs to be replaced then you can ask them to send the optical drive as part/s only and thus no need to send computer back to them. that should be possible even if you only have a depot contract(my friend has a computer with a warranty that includes an onsite technician and has another laptop with a depot contract. that 's how i know).

you can try swapping a known good optical drive to see if it's just the optical drive that is failing.

also, you can send the computer to them without the harddrive if you're afraid of losing files.


best of luck.

Please, kindly help me to fix
the problem as the CD/DVD drive is not able to read the CD/DVD on Sony laptop(Model: PCG-FRV28) and drive model: Matsushita uj-810,
it always shows as blank CD and DVD though those CD and DVDs are good in condition and has content (files)
Since, it was working very good before updating to firmware (C104) and other updates from esupport.sony.com

It seems, the problem after installing the firmware from esupport.sony.com.

And, folowed as mentioning on
http://www.kb.sony.com/selfservice/microsi...%200%2036023852

but, there was no luck,
eventhough removing the upper and lower filters from the registry
and performed system restore to factory installed state from hard drive version, too.

System details?
>>
Sony laptop model: PCG-FRV28
CD/Drive: Matsushita uj-810

The driver details (files):
~ cdrom.sys
~ imapi.sys
~ PxHelp20.sys
~ redbook.sys
~ storprop.dll

OS: Win XP Home edition

Are you able to see any yellow exclamation or question mark next to the CD/DVD Drive in the Device Manager window?
>> NO

Is the CD/DVD Drive icon missing from the My Computer window?
>> NO

Are you getting any error messages?
>> Yes, it popups "I/O errors" and if I uncheck "Enable CD recording" by right click the drive in My Computer, Properties, Recording tab.
>> No, if, I check (enable) "Enable CD recording", then, there won't be any errors. But, it always, shows the CD or DVD as blank, though those have the files and in good condition.

Thanks alot in advance for your kind help or any information.

msreddy,

It is always a good idea to start you own thread as tagging onto anothers will not get you the professional help you deserve.

Please follow this link which is also in my Signature to post your own thread

Thank you.

kind regards,

edi006,

As your computer is under warranty, I strongly advise you to send it back untouched as if you let anyone else open it, or do a thing to it you will void your warranty forthwith. That is what you took out the warranty for or maybe it was offered with the purchase of your new computer.

Yes, always backup before sending the computer back to the Manufacturer. Buying an external Hard Drive is a good idea and purchasing either Ghost or Acronis image backup software would be the way to go. The small investment of the image software is truly the best investment you will make.

Kind regards,
