PROBLEMS
WITH PHILLIPS RECORDERS
Following is some information on the Phillips recorders in
general which has some links to sites which may also help. You might also try to read the
disc at 1x speed for both data and audio if you aren't already doing so.
If you have two CD drives (your burner and a CD-ROM drive),
you might try using your CD-ROM drive to read the disc, then use your burner to write the
image file.
DAE (Digital Audio Extraction) PROBLEM
Some recorders don't correctly extract digital audio if the
pregap of the first track isn't 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.
CDs that start at 00:02:32 (0 minutes, 2 seconds, and 32
blocks) are surprisingly common. The problem can be worked around manually, by looking at
the output of the Jeff Arnold's (freeware) TOC program (available from http://www.goldenhawk.com) and
supplying "/start=" and "/end=" parameters that adjust backward by the
number of blocks in excess of two seconds.
For example, if the first track started at 00:02:32, you
would subtract 32 from the starting and ending Logical Block Addresses.
A better solution is to use a CD-ROM drive that doesn't have
this problem (and most likely can extract audio more quickly than the CD-R can).
The Yamaha CDR-100/102 and the Philips CDD2600 are known to
have this problem, though it may get fixed by a firmware update. The Ricoh 6200S
reportedly does not return the disc's table of contents correctly for these sorts of
discs.

Models are the CDD522 (2x2/2MB), CDD2000 (2x4/1MB), CDD2600
(2x6/1MB), and CDD3600 (2x6/1MB;RW). The CDD3610 is a 3600 with an IDE interface. The
CDD521 (2x2/256K) is an ancient model; if you use one, the firmware upgrade is strongly
recommended (but nearly impossible to find). The Omniwriter/26 and /26A appear to be
repackaged Ricoh 6200 and 6200I OEMs.
The CDD522 does not support reading of subcode-Q data. The
CDD521, CDD522, and Kodak-labeled PCD225 have a sensor that can read the barcode data from
the inner ring on a CD.
See the HP section for comments about the CDD2000 firmware.
The firmware is kept in flash ROM, so it can be updated with software obtainable
over the net. You should be at version 1.25 or later for best results.
Digital audio extraction may not work correctly at higher
than 2x on the CDD2600, especially near the end of the disc. Philips has acknowledged that
audio CDs and packet-written CDs may not read correctly at 6x, but many users have had
problems at 4x as well. It may also suffer from the block offset problem described in
section (4-19). The CDD2600 supports packet writing, but is NOT flash upgradeable.
The CDD2600 may share the HP 6020i's difficulties with
pressed CD-ROMs that have a small amount of data on them.
The initial release (firmware v1.0) of the 3610 was unable
to create audio discs reliably using disc-at-once recording. Firmware v2.02 fixed this and
some other problems.
Philips' drives, notably the CDD2600, have been shown to
hang on some Amigas if SCSI disconnect is enabled and you try to read the session
information from a multisession CD. Philips does not believe this problem happens on PCs,
and consequently has declined to investigate further. If you are experiencing hangs when
examining multisession CDs, try turning SCSI disconnect off for the CD recorder.
Drivers are available for the CDD2000 from: http://www.philips.com/sv/pcaddon/cdr/
Firmware updates are available here: http://www.km.philips.com/osc/cd-rw/download/index.html
CAVEAT EMPTOR - CDD2000. Some users of Philips CDD2000 and
derivative units (like the HP4020i) have reported that the drives went bad over a short
period of time, often 1 to 3 months. While these cases represent the minority of users,
reports have been persistent. People with the technical skills (and bravery) required to
replace a spring and/or lubricate inside the unit have reported good results (see section
(4-10) for details). If you buy a CDD2000-based unit -- of which there are many -- be sure
the dealer or manufacturer is aware of this problem and is willing to fix or exchange the
drive should it arise.
A class-action lawsuit has been filed against Philips.
