YAMAHA CRW-F1DX CD-RW


1. Installation/Package

YAMAHA CRW-F1DX CDR-W - Page 1

- Introduction

After having tested the internal IDE drive (CRW-F1E), we were very excited to see the CRW-F1DX arrived in our labs. The new model from the CRW-F1 series is actual the external version of its twin brother CRW-F1E (already tested) and comes with an attractive look and two different connection interface. We compare both Yamaha drives to see their performance differences, due to different firmware revision.

- Embedded Technologies

The CRWF1 series contain several new technologies. We have already discussed most of them in our CRW-F1E review but we will sum it up one more time.

The CRW-F1 is the first drive to offer a Laser Labelling System with the name DiscT@2. The full CAV technology and precise control of the key elements of recording, (specifically: tracking, rotation, and laser intensity and positioning) allows text and graphic data to be tattooed to the media's data surface after the writing stage is complete.

Under this mode, the system widens the lands and pits during recording. This significantly reduces jitter and improves audio and music recording quality. The new Advanced Audio Master Quality mode now supports 1x and 8x writing speeds as well as the original 4x speed mode. You can select proper writing speed for the media in use, or use the Best mode allowing the CRW-F1 to determine the best writing speed.

The F1 series maintains a constant rotation speed from the beginning of the recording process, on the inner tracks of the disc, all the way to the tracks at the outer edge. The spindle motor of the CD-R unit maintains a constant disc rotation speed of 8700 rpm throughout the entire writing process, while the actual writing speed smoothly increases from 19x to 44x.

Ultra Speed sets the new standard for CD-RW Rewriting at 24x and gives you two high-speed rewriting options depending on the type of rewriting that you need to do. Full CAV mode offers 24x rewriting for random access packet data rewriting, while High-Quality Partial CAV mode does the same for conventional data rewriting.

CD-MRW offers packet-writing capabilities that have not been available until now. Specifically, it has made writing and re-writing files on a CD-RW as easy as to and from a floppy disc while reducing disc-formatting time from 10 minutes down to about 2 and vastly improving management capabilities for damaged disc sectors.

CD-RW Audio Track Edit makes editing a finished CD-RW as easy as editing an MD. Erase the final track or add new songs directly to the CD, without first having to save WAVE files to your hard drive and erasing the entire CD-RW disc, and then play it on your CD player.

Yamaha's original technology - SafeBurn features an 8MB memory buffer, Buffer Underrun Protection, and Optimum Write Speed Control. These three resources combine to provide the best possible writing environment and further optimize reliability.

- The package

The US retail package will include Ahead Nero 5.5.9.9, InCD 3.81, NeroMIX, Nero Toolkit, Nero Cover Designer, MusicMatch Jukebox (PC and Mac), Dantz Retrospect Express, Adobe PhotoDeluxe and Activeshare (PC), Adobe Photoshop LE (Mac), 1 blank CD-R, 1 blank CD-RW (24x), a Quick Start Guide, a FireWire cable, a USB 2.0 cable, the CRW-F1ZDX drive, and power supply.

The price of the CRW-F1ZDX is $279.99 in the US market. The actual retail price probably would be even lower.

There are also two more external versions of the CRW-F1 series with different connection interface:

The external case is impressive and looks solid and stable. The colour is silver with a pair of black plastic stripes on the sides of the drive. The Yamaha logo is embossed on the top of the drive.

The front panel of the YAMAHA CRW-F1DX is silver, not white, with a grey "YAMAHA" logo. In addition you will find, the headphone jack, the volume selector and the eject button. The drive has a special "intense blue" LED that lights up when recording. Above the tray, there is another LED that lights to purple-white (fluorescent) colour when the drive is idle. Lastly the drive has a black tray, as first introduced with the CRW3200 series:

In rear panel, you will find the power connector, the power button, audio output connectors and the interface connectors. The Yamaha F1-DX offers two IEEE1394 and one USB 2.0 connectors. User is free to choose the desired interface, and plug the drive to his PC easily and fast. According to the interface choice, user should move the interface switcher on the right or left, for IEEE1994 or USB2.0.

- Installation

The YAMAHA F1-DX was installed either with the IEEE1394 (Firewire) and with the USB2.0 connection interfaces. Under WinXP, the drive will be detected automatically. Win98SE users will have to install additional drivers that are included in the attached software disc. The drive with the Firewire cable was recognized as:

, while with the USB2.0 as:

In both cases, the drive is identified as a "YAMAHA CRW-F1E" under the CD-R software. The drive is a July 2002 model and came with initial firmware revision v1.0C. Lastly, we used the latest Nero v5.5.9.9, CloneCD v4.0.1.10 and Ahead InCD v3.37 for the recording tests.

- Specifications

Nero info tool reports that the drive supports 44X reading and writing, the firmware installed is the v1.0C and buffer underrun protection is available. The "SafeBurn" features an 8MB memory buffer, buffer underrun protection and Optimum Write Speed Control.

2. Data Reading Tests
YAMAHA CRW-F1DX CDR-W- Page 2

Data Tests

- Pressed CD results: (Click to see the CD Speed Graph)

Yamaha CRW-F1DX and its internal brother seem to have no differences in the data reading performance. The average reading speed is the same for both drives, and none of them reached the promised 44X maximum speed. The seek time results are also identical.

- CDR Media: (Click to see the CD Speed Graph)

The situation could not be different in the CD-R reading test. Again, the results look exactly the same.

- HS-RW media: (Click to see the CD Speed Graphs)

In the HS-RW reading tests we used the HS-RW media that come with the retail package of each drive, recorded in the correspondent maximum speed supported. For the YAMAHA drive, we used Ultra speed 24X HS-RW media. The YAMAHA CRW-F1DX read the disc at 32.98X average speed.


3. Error Correction Tests
YAMAHA CRW-F1DX CDR-W- Page 3

Error Correction Tests

In the following tests we examine the reading error correction capabilities of YAMAHA CRW-F1DX.

- EAC CD-R Test Disc

- Introduction

We used the testing methodology as described in EAC website. The CD-R test disc includes 5 scratches and a black triangle defect. Using EAC's BURST mode, we ripped the test disc with two different files speeds (max & 4X). The attached analyse.exe software used to get the necessary results.

The graph tells a lot about the abilities of the drive. The quality of the optical system (and/or of the error correction capabilities of the firmware) is shown in at which time index the error start. The error hiding qualities are shown when the wedge gets bigger.

The grid of the graph has the following means:

- Explanation

After the analyze finishes, we will get a detailed report about the various errors:

- Errors total tells about the total number of wrong stereo samples. This includes areas of wrong samples that may include some correct samples.

- Errors Loudness is the number of FFT analysis done. For that the average and maximum value tells the power difference of the two signals. No acoustic model is used for this calculation, so the audible error may differ from these values.

- Error Muting tells something about error hiding. On bad errors (or bad error hiding techniques), the last error free sample is held for some time until a new valid sample is found. The number of these mutings is given as first result, following the average and maximum sample length of these mutings.

- Skips are occurring when the sync was lost and the drive had to reposition again (and started on a slightly different position). Non-accurate stream devices would loose the sync very often and smaller and bigger skips occur (thus samples are missing or extraneous). The average and maximum values denote the length in samples of such skips.

- Total Score is calculated according to the previous errors. The higher score a drive gets, the better!

- Test Results (4X Reading)

The YAMAHA CRW-F1DX at 4X, starts reporting errors earlier than with full speed (12mins), but the corrected data ,within the black defect, will stay nearly always below -60 dB(A), which is nearly un-audible if it is surrounded by loud music. The 5 scratches are not fully corrected, but stay below -54 dB(A). As the test results showed, the CRW-F1DX gets 79.1 score out of 100 (max).

- ABEX TCD-721R

- Introduction

This test disc includes artificial scratches with lengths from 1.8 mm to 3.0 mm.

Using the ABEX TCD-714 as the reference disc, we created the reference.wav file that is needed for the comparison. We ripped the disc at full speed, using EAC's copy range and after running the analyse.exe software we got the error graph.

- Test Results (4X speed)

The ABEX TCD-721 causes problems to most of the tested drives, including the YAMAHA CRW-F1DX. The drive reports errors early, at 12mins, but stay below -66 dB. After 20mins, the errors reach -52 dB (average), while many spikes reach up to -10 dB! The drive's overall score is 62.3 out of 100 (max).

- Test Results (Max speed)

At the maximum reading speed, the drive got a better score (70.0) compared to the 4X setting. This can be explained, since the Yamaha CRW-F1 series doesn't support minimum of 4X reading speed, but 10X. The ripping speed in either 4X/Max setting was close, so the results are also close…

- ABEX TCD-726

- Introduction

The ABEX TCD-726 includes three kinds of defects, interruption, black dots and fingerprints are prepared in this disc. The interruption defects are sized from 0.5 mm to 1.0 mm. The black dots are from 0.4 mm to 1.0 mm. Lastly, the fingerprints are from 65 to 75 micro meters.

- Test Results (4X Speed)

At 4X reading speed, the drive showed very good behavior. Only few errors occurred during the 26-28minutes, under -60 dB. The drive gets a high score of 92.4 out of 100 (max).

4. CloneCD Reading Tests

YAMAHA CRW-F1DX CDR-W- Page 5

CloneCD Tests

- Procedure

We used CloneCD (v4.0.1.10) 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 drive. 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 CRW-F1DX drive gave the same result with the CRW-F1E.

- SafeDisc v.2 Results

Both Yamaha drives are fast in the SafeDisc v.2 test, and the actual difference in the performance between them is 1-2 seconds.

- LaserLock v.2 Results

Not much to add here, the drives have the same speed in the LaserLock v.2 test.

- SecuROM v.2 Results

The expected result again in the SecuROM v.2 test, with both drives to finish the task in the same time.


5. DAE Tests

YAMAHA CRW-F1DX CDR-W - Page 6

DAE Tests

- DAE features

- Pressed AudioCD

The YAMAHA CRW-F1DX supports up to 44X DAE. The results showed that there are not actual differences in the DAE speeds of the two Yamaha drives.

- AudioCD-R media

In the CD-R DAE test, the external drive is slightly faster with 30.6X.

- 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 built-in detection function:

- Reading/Ripping Protected AudioCDs

For the test procedure we used 2 protected AudioCDs, which we tested in both recognition and ripping (with EAC) processes:

* Pressed AudioCD with Sony Key2Audio (Celine Dion - New Day Has Come)
* Pressed AudioCD with Cactus Data Shield 200 (Natalie Imbruglia - White Lilies Island)

YAMAHA CRW-F1DX can handle both CDS200 and Key2Audio protected audio discs. This is an issue solved in this 1.0c firmware version, since the IDE model had problems with the Key2Audio protection.


6. CDR Tests

YAMAHA CRW-F1DX CDR-W - Page 7

CDR Tests

The CRW-F1DX series support 1X, 4X, 8X, 16X (CLV) and 44X (CAV) writing speeds. When OWSC (Optimum Writing Control ) is enabled, the drive will select automatically the best maximum possible recording speed from 8X, 16X (CLV), 20X, 24X, 32X, 36X, 40X and 44X (CAV). You cannot select the speeds between 16X and 44X.

The Optimum Writing Control system, determines the optimum writing speed for the disc inserted. The feature can be disabled through Nero software, and as a result, user will be able to record all inserted media at the maximum speed (44X). With OWSC on/off, you can select all recording speeds (1X-44X). When OWSC in enabled and a low quality media is used, Nero will report the drop of recording speed, usually down to 16X:

The complete list of the supported media for the various speeds can be found at http://www.yamaha.co.jp/english/product/computer/discf1.html.

- Full CAV recording method

Using an 80min disc, we can see the drive's start, ending recording speeds, according to the Nero CD Speed software. The drive starts writing at 19.68X and gradually reaches almost 44X at the end of an 80min disc:

The drive also supports 40X P-CAV writing speed that reaches up to 32.99 X average writing speed:

- Recording Tests

YAMAHA CRW-F1DX finished the writing process in 3:07 minutes. The result came with the IEEE1394 interface, with Sanyo Digital 80min 24X media. With USB2.0 interface the best result we had was 3:08mins. The drive is equal fast in both IEEE1394/USB2.0 interfaces. The YAMAHA CRW-F1E was faster in our tests by 4secs and CyberDrive CW088D leads the race at 48X with 156 seconds.

Below is the screenshot of the best recording result:

Nero writing with IEEE1394 interface

With USB 2.0 interface, the best results we had are about 3:08mins:

Yamaha CRW-F1
99mins

The drive can overburn up to 99mins without any problems.

- CD-Text Results

The drive 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 up to 44X (CAV). CloneCD doesn't offer any option to disable OWSC. For checking the drive's EFM correction status, we used 3 different game titles with various SafeDisc 2 versions. For getting the maximum of them, we used the latest software patches. We used the Yamaha CRW-F1DX both as reader/writer at maximum reading/recording speed. We burned two discs for each game (Amplify Weak Sectors On/Off) and the results are posted in the below table:

As the test results showed, the CRWF1DX drive can backup up to SD2 v2.50.020 version without the need of Amplify Weak Sectors. However with the latest v2.51.021+ builds it will not produce 100% correct playback disc. The backup media worked only in the LiteOn LTR-32123S recorder (with Hide CD-R activated) and the YAMAHA CRWF1-DX.

The general writing quality of YAMAHA CRW-F1DX is good and sometimes better than its twin brother (CRW-F1E). No C2 errors reported in any of the tested media. Of course with some media the drive performed better than other. The best results come from Mitsubishi Chemicals 48X (OWSC on), while the worst from EMTEC 24X and SmartBuy 32X media. When user de-activate the OWSC function, will notice major speed increase, compared when is enabled. However the writing quality will be worst. Again this is not that can be said confident, since with Fuji Film 48X media, even OWSC is disabled; the writing quality is very good.

8. HS-RW/Packet Tests

YAMAHA CRW-F1DX CDR-W - Page 9

RW Writing Tests

The F1 series support 24X writing with the use of Ultra HS-RW media. The drive can write at 10X, 16X and 24X with Ultra HS-RW. With 4X-10X HS-RW media, the supported rewriting speeds are 4X, 8X, 10X and 12X (CLV). The CRW-F1DX support 12X re-writing with 4-10X HS-RW only with few media.

With Ultra HS-RW media, the CRW-F1DX drive starts writing at 19.31X and reaches 24.15X at 10mins. The average theoretical re-writing speed is 23.83X:

Using Nero, we saw two different performances, either with OWSC enabled:

or with OWSC disabled:

As it seems, OWSC function does affect the re-writing speed of the drive. When it's enabled, will write almost to 20X (P-CAV) and when is disabled will write up to 24X (P-CAV). Below are the test results, by using either OWSC on/off:

24X writing (OWSC on): 4:16mins
24X writing (OWSC off): 3:46mins
16X writing (OWSC on): 5:30mins
16X writing (OWSC off): 6:02mins

- Packet Writing Tests

We used Ahead InCD v3.37 for the packet writing tests with the 24X Ultra HS-RW media. The formatted disc had 534 MB 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 Windows Explorer (we dragged and dropped) and we completed the test twice to eliminate any possible time measurement faults and user errors:

The external drive was slower in the writing part by 2X, and the reading performance was exactly the same as with the CRW-F1DX.


9. Mt. Rainier Tests

YAMAHA CRW-F1DX CDR-W - Page 9

Mt. Rainier Tests

For testing the Mt. Rainier performance of YAMAHA CRW-F1, we performed two types of tests. The software we used was InCD v3.7.1 by Ahead Software.

First Test

After the format process, we immediately start the recording process (drag & drop). When the drive finishes, we start the reading process back to the HD. At this mode, the drive writes, reads the quality of the written data and background formats the disc at the same time. For the YAMAHA CRW-F1DX we used both 10X HS-RW media and the Ultra Speed 24X HS-RW. The recording performance of each drive is displayed in the below table.

YAMAHA CRW-F1DX showed a slight incensement under packet writing format, compared to the CRW-F1E series.

Second Test

At the second test, we left the drive alone to complete the background formatting and afterwards, we repeated the above tests. The recording/reading performance in this case is higher for all the drives, since now only record & read are performed. The disc has been scanned for bad sectors during the format process.

- EasyWrite tests

The Philips Easy Write tests checks the quality level of the implementation of Mt Rainier feature. Un-fortunately the CRW-F1DX doesn't support yet the EasyWrite test suite commands…


10. Conclusion

- High price

The YAMAHA CRW-F1DX offers many features to users who wish an external desktop recorder. The drive supports both FireWire (IEEE1394) and USB2.0 interfaces, making it a truly universal solution for both MAC/PC platforms. In addition, the CRW-F1DX offers all the unique features of its internal brother (CRW-F1E), DiscT@2, AudioMASTER Pro, CD-RW Audio Edit and of course Mt. Rainier format. There are some performance differences, due to different firmware from the already tested CRW-F1E, sometimes positive and sometimes negative.

Two improvements we saw: the drive now can read/write previously un-supported 99min CDs and handle every AudioCD protected disc! The recording performance compared with the CRW-F1E is somewhat slower but the writing quality is improved. There is no change in the hardware/software "EFM correction", useful for backups. Even with the help of software of software help, the produced backups will not playback accurately in all drives.

Lastly, the design of the drive is really attractive to user's eye and the only drawback maybe the price of the drive that reaches up to $280. Of course the price of all external recorders is much higher than with internal drives. YAMAHA's CRW-F1DX offers extra features, sleek design, and dual interfaces.
