The 7110 is identical to the 7100, but comes with an extra piece of
software and is only available in the USA. The 7200 is a 7100 with updated
firmware (2.x) and Easy CD Creator included. The 8110 is the same as the
8100 but with a bunch of extra software; ditto for 8210 vs 8200. The
6020ep appears to be the external SCSI drive with a parallel-to-SCSI
converter. It's usable as a SCSI device as well. The 71XXe drives are
71XXi drives with a parallel-to-IDE converter. The 7500 series is often
packaged as 7550 or 7570 (though these are now listed as having only 1MB of
buffer, so it's not clear what's going on).
There are indications that HP shipped two different drives as the 8250, both
with the same read and write speeds. The first was the Philips CDD4201,
identifiable by about 18 tiny horizontal indentations along the bottom of
the face, with a hinged "drawbridge" loading door. The second was the Sony
CRX120E, which has 4 horizontal indentations along the bottom of the face,
and no hinged door. The popular consensus is that the Philips versions
are problematic. It may be possible to tell the boxes apart using a code
on the barcode label: C4464A for Philips, C4464B for Sony. (It appears
there may even be a third variety: HP is rebadging Mitsumi 4804TE in their
Pavilion 6648C computers. There doesn't appear to be an HP model number
associated with the drive though, so it may not actually be sold as an 8250.)
It now appears that some 8250i drives are 32x4x4/4MB; these are actually
Sony CRX140E drives (32x8x4/4MB) with firmware that limits them to 4x
recording. It has been reported that, if you can get the HP9100i firmware
onto the drive, it will record at 8x.
There are similar indications for the 7500, which appears to have originally
been a JVC XR-W2080, but is now a Sony CRX100E with a reduced maximum
write speed. Drives based on the Sony mechanism can reportedly be
flashed with the Sony CRX100E firmware update and upgraded to 4x recording.
Most 9100 uints are based on the Sony CRX140, but there are indications
that units identifying themselves as "9100b" is actually a Goldstar
The initial release of the 7100/7110 was unable to create audio discs
reliably with disc-at-once recording. The 2.02 firmware upgrade fixes
Some people have criticized the 8100i (same as Sony CRX100E) for being unable
to write more than about 78 minutes on an oversized (e.g. 80-minute) blank.
It appears that the Sony v1.0n firmware upgrade removes this limitation, but
the upgrade was never made available for the HP drive. Some users have
had success flashing the drive with a "hacked" version of the Sony firmware,
but this can be dangerous (see warnings in section (5-24)). You can also
just use the Sony firmware, but that causes the front LEDs to stop working.
If you are having trouble getting the 7100e to work with your parallel
port, see http://www.hp.com/isgsupport/cdr/tech/7100/par95.html for some
important configuration advice. If your BIOS is configured to use address
03BCh, you should change it to 0378h or 0278h.
It appears that discs written with a 7110 can't be read on a Toshiba
XM6002B. Other models of CD-ROM drives, including other Toshiba models,
work fine. CD-Rs written on other CD recorders work fine with the
Toshiba. The 3.01 firmware upgrade fixes this.
The HP 4020i got off to a rough start because of buggy firmware and
problems with the AdvanSys SCSI controller shipped with the drive. Four
firmware upgrades have been made available so far (v1.20, v1.25, v1.26, and
v1.27), and most but not all problems with the firmware have been
eliminated. HP recommends that users with the v1.20 or later firmware who
aren't having problems should NOT get the upgrade. Contact HP tech support
for more information.
The comments about digital audio extraction problems and the CDD2600 apply
to the 6020i as well. Unlike the CDD2600, the 6020 apparently does not
support packet writing. The firmware is not flash upgradeable. (As it
happens, the SCSI ID string *can* be changed, and it *is* possible to make
the unit think it's a CDD2600. A representative from Adaptec has warned
that the procedure could cause problems later on, however.)
The 6020 with v1.07 firmware also has trouble reading some pressed CD-ROM
discs, notably single-track CD-ROMs with less than 27MB of data.
An unofficial HP 4020i FAQ maintained by Greg Volk can be found at
Drivers, software, and firmware upgrades are available from
The 7100/7110 firmware upgrade is available here:
IMPORTANT - 7100/7110. The 7100/7110 drew a lot of fire because it shipped
with DirectCD (packet-writing software), a CD Copier, and an audio CD
creator. It didn't include premastering software for data CDs. Because
packet-written CDs can't be read on all operating systems or all CD-ROM
drives, the inability to create plain Level 1 ISO-9660 discs was a problem
for some users. People who buy this drive should expect to buy additional
software. The software bundled with the 7200 was more wisely chosen.
CAVEAT EMPTOR - 4020i. See the notes on the CDD2000 in the previous
section. Also, the AdvanSys controller continues to cause problems for
some users, which is made worse by HP's refusal to support people who try
to use a different card. The best approach seems to be to try the card and
stick with it if it works, otherwise buy an Adaptec board (e.g. the 1522A)
and use it with that. There may be a newer rev of the AdvanSys board.
A few 4020 users have reported that, after getting lots of "-24 - Target
aborted" errors with jarnold's software, they successfully resolved their
problems by getting a new drive from HP.
A class-action lawsuit was filed against HP (for the HP4020i and HP6020i)
by the same people who filed the suit against Philips -- the drives were
repackaged versions of the CDD2000 and CDD2600.
