Removing the UpperFilters and LowerFilters registry values from the Windows Registry is a likely solution to several Device Manager error codes in Windows 7, Windows Vista, and Windows XP.

UpperFilters and LowerFilters values might exist for several device classes in the registry but those values in the DVD/CD-ROM Drives class tend to corrupt and cause problems most often.


Important: Changes to the registry are made in these steps. Take care in making only the changes outlined below. While it's not a necessary step to complete this process, I recommend that you play it safe by backing up the registry keys you're modifying.

You can follow the step by step text instructions here. If you prefer a screenshot step by step guide, you can click here.


Hope this information helps!

On acer aspire 5520g the dvd rw spins the dvd but bio's says its unplugged and it won't read the dvd's


Try downloading a driver from the net, Or install DVD software such as Roxio or Sonic Cine Player. Does it show in hardware as a CD Rom or DVD/RW ? If it shows as a CD the driver is the problem.

Acer Aspire 5520 Vista Cannot Read Disc no matter what


You probably need to swap it out, lasers and spindle motors often go bad.
Get a new drive off ebay (you can even upgrade to lightscribe for like 10$ more at this point): http://shop.ebay.com/items/?_nkw=Acer+Aspire+5520+cd+drive
Looks like you need to take the keyboard off and unscrew the screw holding the cd-drive in.

After installing vista service pack 1 my dvd rom is gone.


Download the latest driver for dvd rom from Acer that will work with Vista SP1. Also try uninstalling the device in device manager and restart your computer. Vista may find "new hardware" and install the driver from its driver pack in SP1.
