This is commonly caused by:
1.) Installing burning media or, specifically, iTunes.
2.) Removing that software affects your DVD-ROM driver, GEAR Software's driver. You may see it as a "Lower Filter / Upper Filter" value in the registry or something along-side PxHelp20.sys / GEARAspi.WDM, etc.
If you trust Microsoft's "Fix It For Me," here's the link. It does what I'm about to describe.
Your CD or DVD drive can't read or write media
You can go to GEARSoftware.com and locate the driver wizard to install. Save it to desktop. Do not install it.
Or, you can go to regedit.exe and create a full registry backup.
Then, go back into regedit.exe. Go to Edit / Find, then (only check first 3 boxes, NOT the last, which requires a "full match,") and search for:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
....by highlighting only the key between* the brackets. That path should appear at the bottom of the registry editor pane.
Right-click (in the viewing pane to the right) and delete values that suggest:
1.) ClassUpperFilters
2.) UpperFilters
3.) UpperFilters.BAK
4.) ClassLowerFilters
5.) LowerFilters
6.) LowerFilters.BAK
Once done, immediately exit regedit.exe and restart.
You should see your DVD-ROM drive re-appear in MyComputer/Computer.
A third / final solution is to download (from
www.yamicsoft.com,)
-WinXP Manager, -Win7 Manager, - Win Vista Manager,
...and locate the Repair Center. It's in the first tab. At the bottom under General Repairs (look over a few tabs to the right once you open the Repair Options, clik the "Fix" dialogue button for "FIX Issue with CD/DVD Drive NOT appearing in MyComputer." Immediately restart.
Good luck,
