CD-ROM does not work

The system: a Systemax Venture running WinXP. 224MB RAM (don't know what's with that odd number :whistling: ), 2.5 GHz.

The drive is a Sony CD-RW model CRX230ED (that's what the device manager calls it). In the device manager (through Win+Pause/Break->Hardware->Device Manager), it has a yellow warning triangle (Posted Image). Through (context menu)->properties->general, the Device Status claims that "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing (Code 39)." The Device Type is "DVD/CD-ROM drives"

I don't recall anything ever happening to it to make it stop working, just one day it stopped. It'll open and close, and spin a disc for a while, but nothing ever happens, and Windows Explorer doesn't display the drive at all.

I've already been to the support site for Sony drives, but they didn't have the driver for my make and model. The closest I could find was the CRX230E, but that didn't work. Any ideas? Or do I need to go buy a new drive? Thanks for any help.

Hi knexor2...

Let's take a look at the upper and lower filters for the cd-rom problem. 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} In the right pane, are UpperFilters and/or LowerFilters listed?

if you think its the filters try this

Actually, the filters are usually the problem. Here's an automated script for fixing them, takes the risk of editing the wrong thing away.

Now, if you've deleted some other stuff associated with the drives, you may have done something that this script can't fix. If so, I suggest a repair installation of XP to attempt to correct that.

Fix for missing DVD/CD drives.

Create a text file with the following stuff in it exactly as below and name it FIXCD.REG

Double click on the file and say yes to the merge into registry question.

----------------------- cut after this line, contents of FIXCD.REG -----------------------------
REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
"UpperFilters"=-
"LowerFilters"=-

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdr4_2K]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdralw2k]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdudf]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr]

Have you tried uninstalling the drive from device manager as happyrck suggested? That will sometimes bring a drive back.

Try deleting just the lower filters first, go back to the Registry Editor, make a back up of your registry by clicking "File" in the toolbar and selecting "Export". In the File Name box, type backup, save the file to your desktop, and click "Save"

Then navigate to the key in my first post, right click on "LowerFilters", and choose "Delete". Accept the deletion and reboot.

:whistling: I have no idea how that worked, but it did...it now plays audio CDs (at least, WMP acts like it's playing it, I don't have speakers hooked up right now). You guys are awesome!

Is it safe to delete the backup now, or should I archive it away?
