Can you Ps help me i have a Matsu/Panasonioc LF-D310 RAM/R burner that no longer recognises blank Ram or cd-r/rw discs it was working fine when i last used it (3 weeks) but i dont know what i have done to cause this! I use this drive for bcking up but i also have a NEC 3500 for burning other stuff. The NEC is master and the Mats is the slave. Also i have never updated Firmware on either drive would this cause all the probs?

PsCould you Ps give me a A-Z on updateing firmware if thats the problem! thanks Kindly!
