Firmware upgrade for an internal dvd burner

Hello,

My first time on the website.

Nice work.

i have an internal dvd burner (toshiba sd-r6012) in my laptop. It is a 1x dvd burner. Supports the -r/rw format only.

My question is: is it possible to upgrade an internal dvd burner like mine to a dual format + r/rw and increase its speed?

i bought some blank dvds but i found out later that they are 4x speed and it says for use only in 4x speed drives. If i try and use them, is there going to be any harm done to either the dvds and/or my drive?

Thanks a lot for your help.

Only use a firmware update if one is provided by the company that made your laptop.
