Hi Konan, Welcome to TSF!

There are a couple of ways that might help you with this issue.

Method One: Remove the registry entry

Warning: Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system.

Please Note: If you had installed multiple CD-writing software products on your computer, you need to uninstall the software products before you remove the registry keys.

1. Click Start, and then click Run.

2. In the Open box, type regedit, and then click OK.

3. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Class/{4d36e965-e325-11ce-bfc1-08002be10318}

4. On the File menu, click Export.

5. In the File name box, type savedkey, and then click Save.

6. Click the REG_MULTI_SZ data type UpperFilters, and then click Delete on the Edit menu. When you are prompted to confirm the deletion, click Yes.

Note: If this data type is missing, go to Method 2.

7. Click the REG_MULTI_SZ data type LowerFilters, and then click Delete on the Edit menu. When you are prompted to confirm the deletion, click Yes.

8. Quit Registry Editor, and then restart the computer.


Method 2: Replace the existing driver


1. Click Start, and then click Control Panel.

2. If Control Panel is in Category view, click Performance and Maintenance, and then click System.

If Control Panel is in Classic view, double-click System.

3. On the Hardware tab, click Device Manager.

4. Click the drive with the question mark (?) next to it.

5. On the Action menu, click Uninstall. When you are prompted to confirm the removal, click OK.

6. Repeat steps 4 through 5 for any other drives with question marks.

7. On the Action Menu, click Scan for hardware changes.

Close all windows and reboot the computer.

Please give these two methods a try and post back with the results.

Kind Regards,

I've tried deleting that registry key, no help :( but there is no yellow question mark next to the cd rom all the drivers are up to date and say no problems. :( it has stumped me and my dad.. We cannot figure anything out about it!! Any advice will be tried and much appreciated! :)

chauffeur2

Go into the Device Manager and delete all DVD/CD's and reboot the computer.
When it powers up again, just let Windows 'find and detect' them.
Post back with the results.

Konan128

No luck same problem :(

chauffeur2

Are you using CD/DVD+ media or CD/DVD- media?

Konan128

it wont read any, it will burn CD+ and CD- but it wont read any, or regular cds. Music or data.

chauffeur2

How old is this CD/DVD?
If it is still under warranty, I would be returning it for a replacement.
If it is over 3 years old; then, the possibility is that it wants to be 'retired'.

Konan128

well ive hooked up some BRAND new ones and still the same problem. Maybe i got a virus and it corrupted the drivers? Im stumped as hell :S thanks for trying and helping me

chauffeur2

Can you please give me the Make/Model of this cantankerous contraption, so that I can do a little bit more research for you.

Konan128

one is LG CD-ROM CRD-8482B, and the other is LITE-ON LTR-48247S

chauffeur2

Please try this workaround (you will need your Windows® XP SP2 CD).

(In the event that you do not have a Windows® XP CD with SP2, you will need to 'borrow' one from a friend or colleague, as the manufacturer's "Recovery Discs" will not work in this instance.)

Insert the Windows® XP CD in your drive. (Hold down the Shift Key to prevent it from starting.)

Go Start > Run ...in the box type in sfc /scannow …please take note of the space between the sfc and the /.

This is the System File Checker...it will scan all the Windows® core system files to ensure that they are in their respective correct places, and if not replace them from the CD.

During the scan you may be asked to Insert the CD, if this happens just go retry and let it do its thing.

One important point: While sfc is running, it is not advisable to do any other work, or have any browsers/programs running on the computer, until the scan is complete. (This process will generally take around 45-65 minutes to complete).

Once finished, remove the CD and reboot your machine...all should be "Normal" (hopefully).

Please post back with the result, or if there are any further queries/concerns.

Kind Regards,

Konan128

Well currently i only have the stupid dell restore disk thing :( but they can't be to old im not EXACTLY sure how old they are.. :( Ill try and get my hands on another xp disk.. Do you think upgrading to sp3 will do anything? thanks :)

chauffeur2

Please do not upgrade to SP3 until we get this issue resolved...that could cause more strife that we don't want just yet.

Konan128

Well i think i might have a.. *gasp* bootleg copy of xp laying around .. but its only sp1 :( does that matter?

chauffeur2

Yes it will have to be a SP2-CD for the sfc to perform its function correctly; besides you have SP2 installed, and it (Windows) will not accept an earlier version.

Konan128

WAIT WAIT WAIT. My cdrom will not read disks. So even if i had this disk. I would put it in and it would say... 0 bytes of 0 bytes on this disk... I'm so absent minded lol i just barley thought about it.

chauffeur2

Indeed...a lapse of my concentration...you're Right!

A couple of Questions....

1: How long has this been happening?

2: Have you installed/uninstalled any software/hardware in the last 10 days or so?

Konan128

I'd say its been about 2 or 3 weeks maybe a little longer and yeah some mmorpgs like city of heros/villians. maybe a couple of others and i think a dvd watching utility. All uninstalled. But i think this was after this started happeneing. My dad told me that just one day it started doing it after he burned a cd. My cdr will BURN but not READ :(

chauffeur2

I have asked a colleague to come and assist with this...he will reply shortly.
