Introduction :
If like me you were ever
the owner of one of the early generation of single or dual speed
CD writers you'll understand when I talk about the hours of
frustration sat staring at the burn progress bar frightened
to touch the keyboard or mouse for fear of burning a "coaster".
Those original "burners" were temperamental, slow
and unreliable and with each blank that winged its way into
the bin you usually cursed to yourself and wondered why you
were bothering.
Early development seemed slow with 2x and 4x drives around for
what seemed like a lifetime, certainly to those waiting for
faster and more robust technology to come along and make burning
your own CDs a quick and painless experience.
Fortunately things were to change and these changes came with
the falling prices that made a CD-RW a mainstream option for
the home user. Along came faster drives and more importantly
along came buffer underrun protection in various guises from
various manufacturers.
So what's a buffer underrun?
For those who don't know the simple explanation is that CD's
ideally need to be created in a single continuous step. For
as long as the blank is spinning there needs to be a constant
supply of data fed to the laser. This is partly made possible
by using a buffer, an area dedicated to storing data ready to
be read and burnt. The larger the buffer the more data can be
kept in standby and the lower the chances of the buffer being
emptied faster than it can be filled. Unfortunately even with
large buffers there may still be occasions where your system
is busy doing other things and can't keep the buffer fed quickly
enough, the result is that the buffer gets used up, data stops
flowing and the CD you were burning is once again headed for
that place where all the AOL CDs live..... the bin.
But surely if the data stops
flowing the writer can just stop burning and carry on when the
data is available again? Well yes and no. This is pretty much
what happens today and is the whole basis of buffer underrun
protections like BURN-Proof (Buffer Under RuN
error Proof) and Just Link. If data flow dries up, these protected
drives burn a "flag", a small marker at the end of
the previous section of data that allows the laser to continue
burning from that point when the data starts to flow again.
The reason this couldn't be done in the past is because lasers
simply weren't precise enough to be able to do it. The pulse
control and tracking electronics were so primitive they would
simply burn a "flag" that was so large it would immediately
be seen by the host drive as a data error which would then abort
reading.
Today I want to look at one of the fastest CD Re-Writers on
the planet, Plextor's 40/10/40A, a drive that sets the standard
not only for burn speeds but for reliability and quality too.
The Package :
Although it's hardly a selling
point it's worth noting that the drive arrived well protected
from knocks and bangs.

Inside the box you'll find a very comprehensive
bundle of goodies including an IDE cable, mounting screws, audio
cable, emergency eject tool, 5 blank high speed CD-R media and
one blank high speed CD-RW media. The software side is taken
care of with the inclusion of Nero Burning Rom, a sage choice
from Plextor as it's probably one of the most fully featured
and regularly updated of all the burning software available
and is certainly the software I personally would choose. It
may not be as pretty as some of the other software like Roxio
but it's fast and reliable. Finally comes the driver CD which
also includes the excellent PlexTools utility which we'll cover
in a while.
