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. =)

All Printers Missing – Clean the Print Spooler

Have you ever gone to print, and all your printers are missing? This almost always means your print spooler service is not running, and that usually means that some print job crashed the spooler. Especially if you’re trying to print adobe PDF documents to an HP Laserjet 1010 or 1020 series printer.

Explaining how to stop the print spool service, delete all the active print jobs to that printer, and then re-starting the spool service can be a longer process than it should be. But, if you download and run the attached cool little batch file, it does it all for you in seconds.

I think I have to zip it, or you may not be able to download it. So, download, unzip, and then run it. =)

HP Laserjet 1020 Crashes Spooler

This post is almost more for my own reference than anyone else’s.

I’ve known for years that the updated drivers that you can download from HP for their Laserjet 1020 frequently crashes the Windows Spooler Subsystem. And, chronically crashes it, so you have to clean out the spooler files and then restart the spooler to get your printers back.

This attached file has a revised driver that seems to help with that problem. You need to put them directly into the c:\windows\system32\spool\printers\w32x86\3 folder, and then re-add the 1020.

Anyway, here’s those files:
