I have bought a HP with a 300c fitted (that I now know is a rebadged Philips DVD R/W). It can read and write CD's OK and I have not had a problem with that. It will aslo read a DVD, but nothing will recognise it as a DVD Writer. I have tried updating the Driver, but that is no use. I read somewhere tht perhaps that 300i driver may be of use. Is that so? Can anybody help? I am concerned that I may lose the things tht work if I do anything!
