I am running Windows 7 on my laptop and having some problems with Optiarc DVD RW AD-7560A ATA DEVICE. This laptop was previously having Vista on it and the DVD drive was not working on it. I have tried to follow the solution to delete the UpperFilter and LowerFilters key but that didnt work. When I try to update the driver then it tells me the best driver is already installed. Does anyone know how do I solve this issue? Thanks
