Firmware is the internal control program on the drive itself. To find out what version you have open Hoster and go to Tools/CD/DVD drives. Find the Plextor listed there and the last group of numbers at the end of the description is the version. If it isn't 1.07 then it is out of date and you will need to go to
http://www.plextor.com/english/suppo...s/firm_760.htm and download that version and install it.
Is this happening only with that particular Chartbuster cd or is it happening all the time?
