"The following has been writing by the CTO (Chief Technology Officer) for
Now, since I am an engineer I will give you a technical overview of this
issue and give you the best possible recommendation.
First of all overburning is non commercial, hacker type function. The main
purpose of this (as I am sure you know) is to copy CDs which have more then
74 minutes of data. So, fine I will not dwell on this point. Given that all
the firmware and software and other things are functioning properly the main
clue in overburning is the media itself. There are many media manufacturers
and media models. Some of them claim to be over 74 minutes, some of them
are 74 minutes and can be used for more and some can not be used beyond 74
minutes. The only shore way to know is to try specific kind of media and if
successful stick with that media. As for software programs, I am aware of
two European and one US company that say they support overburning and our
drives. These are CD-RWIN (GoldenHawk), Niro and DiscJuggler (Padus). The
software designers approach is quite simple. They have some type of setting
in their software to allow you to do this and they simply send data to the
drive and hope there are no errors. They clearly say that there are no
Now, in our testing we have only been successful with some Japanese media
(like TDK, TY). However, we did not do the type of DVT testing that
official product releases go through.
So, to summarize there is NO limitation on 8x (8/4/32) for overburning. The
8/4/32 firmware v1.05 is capable of same functions as Other Plextor drives.
My recommendation is to use one of the above mentioned software and try many
different media until you are successful. In worst case try 4x writing speed
when overburning. For your reference you may visit some cites that are on
Here are some good URLs to do background reading on overburning that might
be of help. The first one is particularly good.
Finally, It is Plextor’s policy to officially not guarantee support for
writing beyond 74 minutes on any of our PlexWriter products. Thus, we will
not officially consider this issue a bug or reason for product to be out of
our specification. All items in our specifications we stand behind and
guaranty. I hope I have been of help to you and you continue to view Plextor
as a positive and helpful company. We certainly are proud of our products."
