Because computers don't fix themselves

CD Drive Missing or Not Working

Has your CD drive suddenly stopped working in your computer? It is possible the laser or head assembly has gone bad, in which case you need to buy a new CD drive. And, except for blu ray drives, drives are cheap these days.

However, many times, there’s nothing wrong with your drive at all. It’s just a windows software glitch that disables the drive. There’s one easy way to find out. Follow these instructions:

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet
* Control
* Class
* {4D36E965-E325-11CE-BFC1-08002BE10318}

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters
* UpperFilters.bak
* LowerFilters.bak

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone

If your CD drive suddenly works again, you win! If not, buy a new drive. =)
