[QUOTE=slowpoke2006;2516942]Ok I have tried several firmwares on this drive it will read any cd or DVD that is not a blank. With the GSA-4166b firmware it will read and write dvds and read non blank cd’s. But with the Hp 840b firmware it will read and write cd’s but wont read blank DVDs any more and with the Hp740b firmware it wont read or write DVD’s or CD’s? Anyone have any ideas on how i might can get full function out of it with just one firmware? I dont care if lightscribe works on it or not just so i can burn cd’s and dvd’s. Thanks[/QUOTE]
No drive can READ blank media! There is nothing on blanks…
Firmware flashing has nothing to do with it and you can end up with a deadflashed drive if you continue that way.
Clean the drive properly.
Then start up in SAFE MODE and try to burn CD and DVD using Imgburn.
