The DVD drive on my Toshiba Satelite Laptop isn't working. I have tried it in another laptop and that laptop was able to read the drive. When in my laptop the unit is obviously getting power, but Windows does not recognize it.

Hi lhneumanns...

The drivers should be native Windows drivers so they can't be removed.

Let's take a look at the upper and lower filters for the cd-rom 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?

One other thing - I have set the BIOS so that the boot first looks at the DVD drive; when I turn the laptop on the drive appears to be accessed.

The drive probably IS accessed...up until the point the registry finishes loading.

Right click on {4D36E965-E325-11CE-BFC1-08002BE10318} and choose "Export". Name this file filters and save it to your desktop.

Double click on LowerFilters, delete the value in the Value Data field, and click "Ok". Then do the same thing to UpperFilters.

Reboot and see if your drives are accessible.

I tried your suggestion and it didn't do anything as far as I can tell (the computer boots up fine, but the drive is still unavailable). Any other suggestions.

Go back into Registry Editor and delete both the LowerFilters and UpperFilters keys.

Open Device Manager and right click on the DVD drive...choose "Uninstall". Accept the change and reboot.

How about now?

The Device Manager does not show the DVD drive.
