Technical
Information & Problems
The CDD2600
is a 2X write, 6X read CD-recorder. It is a very reliable
apparate and it wonīt make problems if you know which
limitations it has, and what you have to do to avoid
possible problems. The CDD2600 is the ideal tool for
publishing large amounts of information in compact form on
CD, especially the incremental packet writing function makes
this apparate attractive to all people that have to backup ,
archieve or interchange data. If you are only looking for a
recorder for making audio CDs (CD-DA), than you should
choose another drive. The problem section below, will
explain the problems you can find when burning CD-DA.

Problems
& Limitations:
- Digital audio
extraction (DAE)
may probably not work correctly at higher than
2Xspeed on the CDD2600.
- It
also suffers from the block offset problem.
This means: The CDD2600 does not correctly
extract digital audio if the pregap of the first
track isnīt exactly two seconds. A bug in the
firmware causes the drive to start extracting
slightly past the start of the track, and stop
extracting slightly past the end. This can
result in an audible glitch if the music starts
at the exact start of the track, and can cause
the drive to fail with an error when extracting
the last track on the CD.
- As the
CDD2600
has no Flash Bios, if a software product
needs a Bios version
, the CDD2600 has to be sent to a Philips
service centre. This will cost you time and
money.
- The
CDD2600 has overheating problems. You
will have to spend money for an extra
cooling fan if you want to avoid problems
and you want your CDD2600 to work correctly.
- Though the
CDD2600 is a 6Xspeed reading drive, it will slow
down to 2Xspeed when reading disk that have been
written incrementally (UDF) and are not
finaliced. When using
packet writing software you will have in most
cases a 2Xspeed reading/writing apparate.
- Philips
donīt offer any drivers for the CDD2600. It is
plug&play compatible with Windows95/NT. To
use it with DOS/Linux/Mac you need third party
drivers.
- Sometimes
the laserhead looses the calibration. I think
this has to do with the overheating problem. It
seems that Philips has not used a temperature
resistant lubricant. So the calibration problem
is in reality a lubrication problem. The
laserlens can not be positioned fast and
accurate enough. You can repair this problem
with the following fix
instructions.
- The Philips
has often problems reading
pressed CDs with less than 30 MB data on them.
This seems to be an ISO compatibility problem,
and it only happens with pressed CDs. This
problem only occcurs with the older CDD2600
units.
- The CDD2600
does not support overburning.This means the
recorder is not able to burn more on a CD-R than
the CD-R reports it can handle. So, if you want
to burn more than 74 minutes to a CD-R, you have
to use 80 minutes media.
- The CDD2600
does not support CD-Text.
- The
CDD2600 is not compatible with Windows2000.
Windows2000 has a new service called
"Logical Disk manager" which is timing
out with the CDD2600. You can wait up to 10
minutes to start the explorer!! If you
disconnect/ turn off the CDD2600, everything
works fine :-(
- ERROR
code list:
There can also be a large number of
errors with their own codes. Look at the error
code list of the CDD2600.

Important:
Many people that are
having problems with the CDD2600 while they are burning, donīt
know if there are doing something wrong, or if the recorder
is broken and not working correctly. To all people having
this problem: I remember you that the CDD2600 has an
"Auto selftest". This is how it works:
| Execution: |
- Selftest will
be activated by pushing and holding OPEN/CLOSE
button for one complete Open/Close cycle of the
tray
- At Host
command: Send diagnostics
|
| Visible
effects: |
- At total
selftest start: Green,
orange and red
will respectively light up for about 200 msec.
This will be repeated 3 times.
- At start of
each individual test: The two LEDS will go on
for 0.5 sec. and then the test starts.
- During the
test: The two LEDS remain on.
- At the end of
an individual test: if the test was unsuccesfull,
the red error led
will go on for 1 sec. If the test was succesfull
the green led will
go on.
- At the end of
the selftest: During 5 seconds, the orange
and the green led
will flash if the whole test was OK. In case of
an error, the orange
and the red light
will flash during 5 seconds.
