Have a laptop that is 4 years old and the cd/dvd drive will not work because it keeps bringing up this error "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) I have tryed everything that I can think of including registry cleaner/repair... 4 different ones ( I hate demos) when I go into the control pannel and select add/remove hardware, do the needed steps, it brings up a list of installed hardware, and the cd drive is on the top of the list with an "!" mark. I can select it and it brings up that same error. If anyone can help me with a free registry cleaner that is not a demo, a Toshiba SD R2102 CD-RW/DVD-ROM Burner driver, and/or spread some of your wisdom around or just help I would be verrrrry greatful. if you need more info on the problem contact me and ank for what more that you need. HELP PLEASE!!!!!!!!!!
