Upgrading GCA-4040N

I’ve got in my notebook DVD+RW GCA-4040N. I just got the information, that GSA-4040N is the same drive, but it also records DVD-R discs. Is this true? Shall I upgrade it?

Shall I use GSA-4040B firmware
downloadable here ?

These drives are not remotely similar.

it works burning DVD-R if you make a flash firmware upgrade …go to … http://tdb.rpc1.org/#GWA4040N and download and install 1.02 (ARIMA) Windows driver upgrade …it will work for DVD-R with 4x …with Nero Burning soft ver 7
