Need drivers for hitachi model gsa-h21n dvd burner

drivers are not needed in order to cd to work, but this problem has aleazrdy been registered.
you shoul click on START, RUN, and type "regedit"
then search in the tree the branch
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
in this, remove the Upperfilters & Lowerfilters values.
reboot, it should work
if really not working after that, download and install the firmware update you can download at http://drivers.softpedia.com/get/FIRMWARE/LG/LG-GSA-H21N-Firmware-A03.shtml
