1. Introduction
INcoder
GH32U-A1 CD-RW - Page 1
- Introduction
is
a new company that aims to ship optical storage solutions for the portable users.
External USB2.0 is the latest trend of the optical storage industry. Many manufacturers
ship external drives, mostly based on the USB2.0 connection interface, since
it offers increased portability among with easy installation. The GH32U-A1 supports
both CD/DVD formats in one package.
- Specifications
The INcoder GH32U-A1 supports the Z-CLV recording technology and the CAV reading
technology. The drive's features according to Nero Info Tool are the following:
The drive supports 40X (CD) and 8X (DVD) maximum reading, 32X writing, and
12X re-writing speeds. Buffer underrun protection is present and the drive has
an RPCII protection. The cache buffer is 2MB and reading of CD-Text and CD+G
is supported. Nero Info Tool reports that C2 error information is also supported
but its accuracy will be examined later. The drive has RPCII region protection.
Lastly the Mt. Rainier format is not present.
- Recording/Re-writing speeds
The drive reaches 32X speed with the use of Z-CLV recording technology. Below
is the Nero CD Speed writing graph that illustrates the implementation of Zone-CLV:
The 32x writing speed range is divided in 3 zones: The drive starts writing
at 16X from the lead-in area till 16mins, shifts up to 24X at 17mins, and lastly
shifts to 32X at 42mins and stays there until the end. The average recording
speed is 25.82X, as Nero CD Speed shows. The speed is slower than with other
internal 32X writers.
- The package
We got the retail version that includes: the drive, 32X CD-R media, 12X HS-RW
media, a DC adapter and the USB2.0/1.1 cable. The attached software comes from
Ahead (Nero Burning Rom, InCD) and InterVideo (WinDVD software). A printed manual
that explains the basic installation and a diskette with device driver for Win98SE
are also bundled.
Looking at the front panel, we can see the "INcoder", "HS-RW",
"DVD-ROM" and "32X/10X/40X" logos printed on the tray. The
eject button is placed in the top right corner and is backlighted with a blue
electric colour. Two leds can be found in the front (orange/green), which indicate
the drive's operation status.
The futuristic design of the drive is clearly defined in the following picture.
The exact same drive comes also in a white bezel
On the rear panel we will find the DC-in power connector and the USB2.0/1.1
compatible connection interface. Note that the drive is also available with
a FireWire interface also.
On the bottom of the drive we can see the model's codename:
- Installation
The INcoder GH32U-A1 was connected with the included USB2.0 cable. The drive
was recognized as an "HL-DT-ST RW/DVD GCC-4320B". We used Nero
v5.5.9.17, CloneCD v4.1.0.1 and Ahead InCD v3.51.61 for the recording tests.
The drive came with v1.00 firmware revision, which is the latest version available.

DVD reading tests
- Test Method
We used Nero DVD Speed to run the DVD reading tests. All the tests were performed
at least 3 times with the same DVD title (we show the average results). The
tests discs were one single sided, single layer DVD-ROM, one single sided, dual
layer DVD-ROM, DVD-R,-RW, +R and DVD+RW.
- Single Layer DVD-ROM reading: (Click
for DVDSpeed results)
The INcoder GH32U-A1 supports the 8X CAV maximum reading speed. The average
speed with the TDR-820A test disc was 7.67X
The seek times with the single layer DVD-ROM disc was very good. The drive
needed only 99ms for the random and 187ms for the full stroke test.
- Dual Layer DVD-ROM reading: (Click
for DVDSpeed results)
With the dual layer DVD-ROM test disc, the drive was slower with
a 6.13X average reading speed.
The seek times for the dual layer DVD-ROM test disc were slightly
increased compared to the results with the single layer disc. However, the performance
is high.
- DVD Ripping Tests
We measured the DVD Ripping speed by using the "Matrix" DVD Video
title and DVD Decrypter v3.0 software.
The ripping speed of the INcoder GH32U-A1 was very good with
an 8828Kb/s average ripping speed!
- DVD reading Tests
The charts below shows the Nero CD Speed results with the following media.
The drive didn't have any problems to read any type of DVD recordable/re-writeable
media we used. The average reading speed in all cases is similar (4.58-4.64X).
5. DVD Error Correction Tests

DVD Error Correction
tests
In the following tests we examined the DVD error correction capabilities.
For the tests we used CDVD Benchmark v1.21 and Nero DVD Speed. The reference
test discs come from ALMEDIO.
- Single Layer media
ABEX TDR-821
This is a single sided, single layer DVD-ROM with a 4.7GB capacity, with scratches.
The drive ends the reading test without any reading errors. The drive lowered
its reading speed after the size of the artificial scratch exceeded a specific
limit but no read errors occurred.
ABEX TDR-825
This is also a single sided, single layer DVD-ROM with a 4.7GB capacity. The
disc contains defects and fingerprints. The drive did not have any problems
to read the disc contents. The yellow dots correspond to the current speed in
each area of the disc. No read errors were reported.
- Dual Layer media
ABEX TDR-841
This is an 8.5GB dual layer, single sided DVD-ROM disc with artificial
scratches with dimensions from 0.4 to 48 mm, in both layers. The result is very
good, as it was expected, judging from the reading test with the single layer
disc.
ABEX TDR-845
The disc is an 8.5GB dual layer, single sided DVD-ROM disc with
defected areas and fingerprints. Again the drive easily overcomes the defected
areas and successfully finishes the reading test.
ABEX TDV-541
The TDV-541 is a single sided, dual layer DVD-VIDEO disc (8.5GB)
with scratches. The performance was not very good since the drive aborted reading
after the drive passed over the second layer.
ABEX TDV-545
The TDV-545 disc is a single sided, dual layer DVD-VIDEO disc
(8.5GB) with artificial black dots and fingerprints. The test was successful,
with a 6.21X average speed and 138 ms for the layer change time.
6. CloneCD Reading Tests

CloneCD Reading
Tests
- Procedure
We used CloneCD and 4 original CDs - Serious Sam 2 (SafeDisc 2), Desperados
(LaserLock 2), V-Rally 2 Expert (SecuROM 2) and NBA Jam Extreme (PSX) - in order
to test the reading time of the drives. We also tested the reading performance
with backups of the original CDs, since the reading speed varies between original
and backup media. The following pictures show the drive reading/writing capabilities
as CloneCD reports:
- PSX Pressed Media
For this test we used the PSX game 'NBA Jam Extreme' and we ripped the image
to the HD with CloneCD. The drive needs only 53secs to finish the task, almost
the same time as ASUS CRW3212.
- SafeDisc v.2 Results
The drive needs 18mins to end the task. The internal drives are not much
faster, and only ASUS CRW3212 gave a higher result.
- LaserLock v.2 Results
With the LaserLock v.2 protected disc, the drive finished after
35 minutes. The Asus drive is still the fastest in the test.
- SecuROM Results
Incoder GH32U-A1 can read SubChannel data from Data/Audio tracks. 4:13 minutes
were enough for the drive to make the image file to the hard disk.
7. DAE Tests

DAE Tests
- DAE features
EAC v0.9 reports that the drive doesn't cachine data, supports "Accurate
Stream" and can retrieve "C2" error information.
- Pressed AudioCD results
In this test we examine the DAE speed of the drive. The INcoder drive was
fast enough to get the second position below ASUS CRW3212 with a 29.3X. No errors
produced while ripping the disc.
- CDR AudioCD results
With CD-R media, the ripping speed reached the 30.1X, which is high enough
to get again the second best position.
- EAC Secure Extract Ripping mode
EAC's secure extract ripping mode results, which ensures maximum produced
WAV quality. Note that for each drive we used the build-in detection function:

- Page 8
CDR Tests
We tested the drive with latest version of Nero/CloneCD. The drive supports
only 8X, 16X (CLV) and 24X, 32X (Z-CLV) recording speeds. For all the recording
tests, we used slightly more than 80min of data (80:01:47).
- Recording Tests
The INcoder drive was the slower recorder in all the recording
speeds. The Z-CLV implementation was slower than the other 32X Z-CLV recorders.
At the maximum speed (32X) it needs 3:53mins to end the task. The CyQve 3248
is faster by 19 seconds.
- Writing quality
We used Plasmon media and burned them at the 32X speed. The results are illustrated
in the following table.

The produced writing quality is high with certain media. The drive did not
work well with Imation (CMC Magnetics) CD-R media since it may wrote it at 32X
but produced C2 errors. The best results came with Taiyo Yuden 32X media (0.6
C1 average error rate).
- C1/C2 error graph from Imation 80min 32X @ 32X
- C1/C2 error graph from SanyoDigital 80min 32X @ 32X
- Overburning Tests
The drive can overburn up to 99mins.
- CD-Text Results
Both drives can read/write CD-Text without any problems.
- CloneCD Writing Tests
The CloneCD software reports that the drive supports the DAO-RAW feature.
With the use of proper media, DAO-RAW writing can be performed at 32X (CAV).
For checking the drive's EFM correction status, we used 3 different game titles
with different SafeDisc 2 versions with the latest software patches installed.
We used the drive as reader/writer at maximum reading/recording speed. Two discs
were burned for each game. One disc was burned with PadusDJ and the other with
CloneCD (Amplify Weak Sectors On). The results are posted in the following table:

HS-RW Writing Tests
We used Nero Burning Rom for writing a HS-RW media at the maximum speed (10X).
The drive was slower than the other drives (12X) due to its lower re-writing
speed (10X). The task was finished in 7:56mins.
- Packet Writing Tests
We used InCD and a HS-RW media for all Packet Writing tests. The formatting
of the media takes around 10min. The formatted disc had 530mbs of free space.
We copied a 403 MB file (403.147 kbs) from a Hard Disk (on the same PC as the
writers) to the formatted RW media-using explorer (we dragged and dropped) we
completed the test twice to eliminate possible time measurement faults and user
errors:
In the writing part, the drive gets the third place with 6.92X average writing
speed, and is the second fastest reader with 17.22X.

The INcoder GH32U-A1 is an attractive proposal since it offers increased
writing/reading speeds for CD format, while it supports reading of DVD discs.
Its 32X writing, 10X re-writing and 40X reading speeds of the CD format are
the faster you can find nowadays in the combo market. The 8X DVD reading speed
can be considered as satisfactory for our daily needs.
On the positive side, the drive's external design is unique, worked fine
under the USB2.0 interface, supports Buffer Underrun technology, can rip DVD
movies in high speed, can read ALL types of DVD recordable/re-writeable media
and its DVD error correction is very good with a read failure in a particular
test. Continuing presenting the positive's we should mention the ability to
backup SD2 protected discs without the need of special software. Audiophiles
will find the DAE speeds high among with the presence of C2 error information
that can be retrieved with high accuracy. Last but not least, the drive can
overburn up to 99mins.
On the negative side, the writing speeds are higher than with internal writers,
the drive cannot handle any type of Audio protected disc, it offers average
CD error capabilities and possibly won't read any medium-high damaged AudioCD.
Even it can write 99min discs, it won't read them back since the process will
stop at around 90mins.
