I am still looking for a solution or a "known issue" response in regards to LG drives not reading discs under Windows 7. I have posted on this forum multiple times and have been given suggestions by moderators (all of which I have attempted).
Please, I still am using a machine that does not have a CD/DVD drive that reads. Here is a list of EVERYTHING that I have done to rectify the situation (mods, please note that I HAVE attempted the Upper/Lowerfilters fix and that the Upper/Lowerfilter entries DID NOT exist; note that Devcon confirms that the filters do not exist).
The drive model is:
LG GH22NS30 Super Multi - DVD±RW (±R DL) / DVD-RAM drive - Serial ATA - 48x (CD) / 16x (DVD) 48x (CD) / 20x (DVD±R) / 12x (DVD-R DL) / 16x (DVD+R DL) 32x (CD) / 6x (DVD-RW) / 8x (DVD+RW) / 12x (DVD-RAM) - Internal - Black
-- Drive is recognized by Windows 7 (can be seen in Explorer and Device Manager)
-- BIOS will recognize discs and prompt for booting (should the disc be a boot disc)
-- I have tried removing the Upper and LowerFilters in the registry; NEITHER value existed when I searched for them
-- I have uninstalled the drive, both physically and via device manager
-- I have run Devcon to determine the parameters of the drive; this is the resulting information:
