CD/DVD Writer doesnt write on certain empty CDs/DVDs

If you just bought some empty Cd's or DVDs and realise that you cannot record any data to them but you can record to the current stack of Cd's that you had before then the problem might lie in the Firmware of the writer itself.
Certain writers were made to record only with certain tested brands of Cd's or DVDs when they were first made.
As time went buy new media or brands were released into the market that the writer does not support.
The best way to fix this is to go to the manufacturers site of your writer and download the latest software firmware for it.
After doing the update the writer should be able to record to the new bought media.
