LG GCE-8481B does not see driver

A Microsoft engineer helped me perform a 'manual reload' of XP Pro yesterday (my fault, I changed CLSID permissions and chose an option that screwed things up and Windows would not load). A few applications were hosed and I need to reinstall them.

Unfortunately, the CD-RW doesn't work at this point (no probelms before reload). It is an LG GCE-8481B drive, and I was able to find a driver at LGE.com and at OpenDrivers.com. I downloaded and installed the software. I then tried to Update Driver in Dev Mgr to no avail. I then Uninstalled and Reinstalled to no avail. The drive's Properties say "unable to load driver".

Is this now - officially - a hardware issue? What more can I do? I am thinking about backing everything up and doing a reload, but with services packs, patches, software installation, etc., that is no small process these days.

Any ideas would be appreciated.

Hi glcarteraz...

Let's take a look at the upper and lower filters for this 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?

Go back to the registry key, right click on {4D36E965-E325-11CE-BFC1-08002BE10318}, and choose "Export". Save this to your desktop and name it cdbu.

Now, in the right pane, right click on LowerFilters and choose "Delete"...accept the change. Do the same for UpperFilters.

Close Registry Editor and reboot. Do you have the drive back?

I have my drive back. I did a 'manual reload' with Microsoft and have access to my drive, but there are alot of issues to resolve (Norton's stuff has basicalliy disappeared though the root folders are in the Start Menu, Pest Patrol has been corrupted in some way, etc. etc.

I'll do the above and let you know if this solves the problem. Thanks so much.

Exactly what procedure (manual reload) did you do? Was it an in-place upgrade (Repair Install)?

Microsoft calls it a manual reinstall -- not through Recovery Console or System Restore. I don't know what Repair/Install means -- that would be good to understand. All I know is to run chkdsk c: /r to repair a directory structure.

BTW, the CD-Rom problem was never solved and -- oh BTW -- it will not boot up just as it didn't before the 'manual reinstall.' So I am going to use PC Relocator and do a fresh install -- this has been a huge waste of time and I would have just done the fresh install earlier but I dreaded all the hours of updating Windows, etc. But I've already spent more time than I would have spent doing that, so it's time to step back 3 paces and punt.

Thanks, though for your reply. I appreciate the time you and others take to help the community out.
