Yes.  The Mitsumi CR-4801TE and later models support DAO.  Mitsumi CR-2600TE and CR-2801TE do not support DAO.  Most CD recording software programs do not recognize this feature.  Adaptec Easy CD Creator does not support DAO. CeQuadrat WinOn CD 3.6 supports DA0. 

Mitsumi drives have previously encountered difficulties reading CD-R discs written from Hewlett Packard CD-R drives. Hewlett Packard has developed a firmware upgrade to correct this problem. This upgrade can be obtained from the Hewlett Packard website: http://www.hp.com/isgsupport/cdr/70index.html.

Make sure the CD-R is listed in Device Manger with no conflicts. Do not have any DOS drivers loading for the CD-R or any CD-ROM.  Do not have anything running in the background.

It is normal for the CD-R to make some noise. As long as the CD-R is reading and writing you shouldn't be too concerned with the noise.

TO TEST YOUR MITSUMI CD-R DRIVE (For CR-2600TE, CR-2801TE and CR-4801TE)

DICDR.EXE DIRECTIONS

Disc Inspector is a program that tests the CD-R drive.

Disc Inspector is a program that tests the CD-R drive. Use the floppy diskette that came with your drive for DOS driver installation and drive testing. Disc Inspector (DICDR.EXE) must run from DOS, not DOS Windows. Be sure to reboot the system to DOS before proceeding.

1. If running Windows 95, restart the computer in MS-DOS mode. Select "Start", select "Shut Down..." and select "Restart the computer in MS-DOS mode".

2. Insert the supplied installation disk into drive A (or B). Be sure the write protect notch is in WRITE ENABLED (CLOSED) position. Disc Inspector will write a log file to the current logged directory. You may copy all files from the installation disk to your hard disk subdirectory, such as C:\DICDR, so that Disc Inspector is available for future use.

3. From the DOS prompt, type A: (or B:) and press ENTER.

4. Type DICDR and press ENTER.

5. Follow the instructions on the screen.

6. Hit the enter key to start analyzing the system’s hardware.

7. From the Drive menu choose Run Tests.

8. Using the left and right arrow keys, choose CD-R

9. You should see a description of the CD-R model number, port address, IRQ, drive jumper designation, and firmware version. If you do not see any CD-R drive, power off the computer and check the power and 40-pin cable connections.

10. To run a test, hold the Alt key and hit the highlighted letter. (Alt-M for Loading mechanism/Interface, Alt-A for Audio, Alt-D for Data/Media, and Alt-R for CD-R)

11. You will see a passed or failed message after the test is done. Passing these tests will verify that the drive is working properly. If any of the tests fail, refer to the troubleshooting section for help.

12. Hit the Esc key to exit the testing section.

To install the DOS drivers (required only if using your CD-R under DOS)—Skip to 15 if not installing drivers:

13. From the Install menu hit the enter key.

14. Follow the instructions on screen using the driver default settings.

15. When the installation is complete, remove the floppy diskette and POWER OFF the computer.

16. Power on the computer and reboot the system.

Disc Inspector Problems

CD-R Troubleshooting tips:

If the CD-R drive in the CR series was not detected when your system was analyzed by the Disc Inspector, you have an IDE configuration problem.

1. Find out where the CD-R drive 40pin cable connects (what card?) 2. Use this web site to solve the problem.

Make sure you are using a blank CD-R disc for the CD-R test. This will perform a Non Destructive Writing Test. The blank disc will still be able to be used for recording.

Only Mechanical and Interface test failed:

This is a hardware issue and will cause the other tests to fail.

Only the Audio test failed:

This is probably a hardware issue.

Only the Media test failed: This may be hardware or software related.

Only the CD-R Calibration/Write test failed:

**NOTE**The Data & Audio Test can not be ran with burnt CD's. These two tests need to be ran with manufactured CD's.

If you have additional questions after following the above instructions, please call technical support at 1-800-648-7864.

You need to disable bus mastering if you have it on your system. This is a known problem with IDE recorders. To find out if you have it and how to get rid of it, you will need to contact the maker of the computer. You should not have anything running in the background when you are writing to a CD. You should press Ctrl Alt Delete and end task on everything except Explorer, systray, and the writing software. Make sure you don't have any lines in the config.sys or the autoexec.bat that refer to a CD-ROM. Try using one of the three recommended brands of media. They are TDK, Kodak, and Taiyo Yuden.

I would like to have a little more explanations over the last firmware upgrade for my CDR. I have a CR-2600TE, may I use the CR-2801TE firmware upgrade?

No, you can not use the same firmware upgrade for both models.

Unfortunately, there is no way to go back to an old firmware revision without a serious chance of causing damage to the firmware on the drive. Previous versions are not routinely made available. Please contact technical support for further assistance.

All Mitsumi CD-R/RW drives supports 80 min CD-R media with the latest firmware uprade.  Please refer to the Drivers and Manual section of Mitsumi.Com.

Can I record Karaoke CDs on any of the Mitsumi CD-RW Drives?

No. Mitsumi CD-RW Drives do not support Karaoke disc recording.

Buffer Underrun Trouble-shooting

GRI:Write Blocks failed, Invalid field in CDB, Block xxxxxx GRI:Write Blocks failed: write error.

**The above message = Buffer underrun**

CD writing is a real-time process which must run constantly at the selected recording speed, without interruptions. The CD recorder's buffer is constantly filled with a reserve of data waiting to be written, so that small slowdowns or interruptions in the flow of data from the computer do not interrupt writing.

A buffer underrun error means that for some reason the flow of data from hard disk to CD recorder was interrupted long enough for the CD recorder's buffer to be emptied, and writing was halted. If this occurs during an actual write operation rather than a test, your recordable disc may be ruined.

Possible Causes of Buffer Underruns

Hard Disk

• "Dumb" thermal recalibration.
• Fragmented hard drive.
• Sector size at 32kb instead of 16kb. (Write from a hard disk partition no larger than 1gigabyte.)
• Not enough space in temporary directory.
• Hard disk compression may cause buffer underruns. We do not recommend writing from a compressed hard disk or disk partition.

Hardware

• Slow source devices.
• Source devices that transfer data in bursts. Incorrect recorder controller settings. Inability of the devices to sync properly. Overall system configuration.
• Computer unable to allow fast enough data transfer.
• Conflicts with old device drivers. Do not use 16-bit (real-mode) device drivers in Windows 95 or Windows NT. REM out any old CD-ROM drives you may have in your CONFIG.SYS file. (You don't need them anyway.)

Memory-Resident Programs

• Any program that may activate on its own Anti-virus software
• Screen savers
• System agents
• Schedulers
• TSR (terminate and stay resident) software Networks
• System sounds
• Animated icons

Networks

• Recording across the network (usually too slow to maintain adequate throughput speed).
• Incoming e-mail or faxes.
• Other people accessing your computer.

Windows 95

• Modify Virtual Memory Settings.
• Disable Auto Insert Notification.
• If you have more than 16 MB of RAM, change the hard drive's Typical Role to Network Server.

Files to Be Recorded

• Recording many small files.
• Damaged source files (data loss).
• Trying to record files in use by the system or other applications.

Other

• Copying from or writing to a CD that is scratched, dirty, or damaged.
• Recorder malfunction.

Checks / Prevention

Disable or remove everything in the computer EXCEPT the operating system, the recording software, and the drivers for your source devices. Defragment your hard drives at least once a week.

Do not record across a network. Copy the desired files to your local hard drive.

Log out of any networks if possible, including Windows for Workgroups and/or Microsoft Network.

Make sure your hard drive does Smart Thermal Recalibration. (That is, it won't recalibrate if the CPU is being used). Record at a slower speed.

Write an .ISO image to hard disk first, if you have enough space. Always write audio at 1x.

Keep the CDs, the recorder, and your source CD-ROM drive free of dust.

Make sure your SCSI controller card is FULLY ASPI-compliant.

Do not try to copy empty directories, zero byte files, or files that may be in use by the system at the time of recording.

More than 10,000 very small files should be written to an .ISO image first or recorded at 1x speed.

The temporary directory should always have space free at least twice the size of the largest file you are recording.

The entire computer, from the motherboard bus to the recorder itself, needs to be configured properly for faster recording and highest maximum sync transfer rate.

Change the DMA transfer rate for the card being used.

With DOS 6.22 or below and a source hard disk 1 gigabyte or larger, partitions should be kept smaller than one gigabyte so that hard disk sector size is 16kb instead of 32kb.

Try a different hard disk and /or gold recordable disc.

Windows 95 Settings

Virtual Memory (if you have more than 16 MB of RAM)

1.Right click on My Computer.

2.Select the Performance tab.

3.Click on the Virtual Memory button.

If you have:

8-bit color, select 16MBs for both the minimum and maximum size 16-bit color, select 16MBs for both the minimum and maximum size 24-bit color, select 32 MBs for both the minimum and maximum size 32-bit color, select 32 MBs for both the minimum and maximum size

Hard Drive Typical Role (if you have more than 16 MB of RAM)

1.Right click on My Computer, click on Properties 2.Select the Performance tab.

3.Click on the File System button.

4.Choose the Hard Disk tab.

5.Change "Typical Role of this machine" to Network Server. This re-prioritizes the hard drive so that it is given priority over other hardware and software functions

Turning Off Auto Insert Notification

Note: You should do this for every CD unit on your SCSI bus, including the CD recorder itself!

If your recorder is not recognized by Windows 95, and you are using Easy-CD Pro, you can download a driver to make your CD Recorder work as a multisession CD-ROM reader under Windows 95. Note, this driver will NOT install unless it detects Easy-CD Pro 95 installed on your system. It does not work under Windows NT.

1.Right-click the My Computer icon on the desktop.

2.Select Properties from the menu. The System Properties dialog box opens.

3.Click the Device Manager tab.

4.Click the plus sign next to the CD-ROM icon until you see the name of your CD drive. Select it.

5.Click on the Properties button. The Properties dialog box for your CD drive will open.

6.Click on the Settings tab.

7.Deselect "Auto insert notification."

8.Restart your system as prompted.

If you are getting buffer under runs, these errors are hardly ever an actual problem with the CD-R drive. They occur because information is not getting to the CD-R fast enough. You should not have anything running in the background when you are writing to a CD. You should press Ctrl Alt Delete and end task on everything except Explorer, systray, and the writing software. If you are copying from one CD-ROM to another then you need to make sure that it is transferring data and audio fast enough. You can go into Easy CD Creator and click on Tools and then System tests. Run the tests on the CD-ROM and hard drive. They should be transferring at about 800 kb/sec to be able to write at 2x with no problems. The small file rate for the data transfer is the one to look at because most files are under 6 MB in size. If you are trying to copy a large amount of data then you need to have as much free space on your C drive as you are trying to write. The ideal thing to do is if you have another hard drive or another partition that has over 650 MB free, go into Creator and pick Tools and Options and change the temporary folder from C:\Windows\Temp to the other drive.

Currently Mitsumi CD-R drives CR-4801TE with firmware version 2.01 or later support DAO.

CD-R drives CR-2600TE and CR-2801TE do not support DAO.

The drive should be able to write just about anything that you can put on the hard drive. The software limits what file types can be written.

Why does my CD-RW always has error with Adaptec software?

The error happens when the ASPI Layer fails.  Download ASPICHK Utility on Adaptec's website and run the program.

I tried creating an image(*.iso) with Adaptec Easy CD Creator Deluxe 3.0 already patched with the drivers for my Mitsumi CD-R, it creates the *.iso file without any problem, but when i want to burn it later on...the program crashes in preparation to write the track, but it burns other *.iso files created by another person without any problem. What am I doing wrong?

You need to upgrade your software to the latest version. This upgrade can be found at:

http://www.adaptec.com/products/overview/cdrgrid.html

You can also download the manual for Easy CD Creator at:

The name of the file you want is CDC_STD_UG.EXE. You need Adobe Acrobat Reader to view this file. If you don't have this program you can download it at Adobe’s website at http://www.adobe.com/prodindex/acrobat/

No, most Mac CD's that you try to read on a PC will just show up as blank. This is not a problem with the CD-ROM drive, this is just an incompatibility between Mac and PC. Can you read these CD's with another CD-ROM on the same system? If you can, then they aren't Mac CD's they are Hybrid CD's.

You need to disable bus mastering if you have it on your system. This is a known problem with IDE recorders. To find out if you have it and how to get rid of it, you will need to contact the maker of the computer. Make sure you don't have any lines in the config.sys or the autoexec.bat that refer to a CD-ROM. Try using one of the three recommended brands of media. They are TDK, Kodak, and Taiyo Yuden.

The software that we provided with the drive should allow you to make backup copies of your games unless they are copy protected.

The files have to be cross platform files but non-executable files. You also have to create the CD's in the ISO9660 format.

About Digital Audio Extraction

Copying audio digitally from a CD requires a CD-ROM drive or CD recorder which supports digital audio extraction (DAE).

All CD recorders can perform DAE. Many CD-ROM drives do not support DAE at all; others do it, but not very well. Few (if any) high speed CD-ROM drives can extract audio successfully at or even near their top-rated data speed.

Unsuccessful audio extraction is easy to detect: it sounds bad (clicks, pops, or hissing within the track). The most common reason is that DAE was performed at too high a speed for your source CD-ROM or CD recorder to maintain proper synchronization of the audio data it was passing to the hard disk or CD recorder. Audio samples are skipped or repeated, causing errors which sound to the human ear like clicks, pops, or hiss.

The solution is to slow down DAE. However, with some drives, getting a clean audio extraction requires reading at very slow speeds, with lots of going back and re-reading the same audio samples over again to make sure that everything is in the right place (this is called audio-resynching or jitter correction). Sometimes the read will be so slow that it becomes impossible to

copy directly from your source audio CD to the CD recorder - the read speed is slower than the recorder's write speed. In this case you will have to copy the audio tracks to hard disk and then record them back to CD.

For Best Results

If you hear pops, clicks, or hissing within a track, slow down! Here's how:

Easy CD Creator

Use the Audio Extraction Settings (available in Easy CD Creator versions 3.01 and later).

CD Spin Doctor

Slow down the read speed of the CD recorder or CD-ROM you are copying from:

1.When the drive is selected as the music source, its name appears below the Select Music Source button. Right-click on the name.

2.Select Properties.

3.Select the desired Current Read Speed from the drop-down menu.

Mitsumi currently does not bundle MP3 software with its CD-R drives. You may want to visit WinAmp’s website and download WinAmp software which has the ability to convert the MP3 into a WAV file. www.winamp.com/download/index.html

Under Windows 2000 environment, Mitsumi recommends you do not install UDF Reader.  Install Nero Burning Rom and InCD only.  Installing UDF Reader in this environment may cause problems.

Where do I get support for this software?

This version of ToGo is not licensed in the United States. Please contact Mitsumi Germany for support and a replacement floppy. Their email address is: support@mitsumi.de.

Make sure you don't have any lines in the config.sys or the autoexec.bat that refer to a CD-ROM. If you want, you can email me copies of these files and I will tell you what needs to be removed. Also, on some systems Direct-CD can cause the system to slow down. This is because packet writing is always checking the drive. It is always running in the background. Just to factor some things out, I would uninstall Direct CD and leave only the Easy CD Creator on the system. Then see if the performance is any better. Try using one of the three recommended brands of media as well. They are TDK, Kodak, and Taiyo Yuden.

Direct CD Version 1.01 CS is not compatible with Windows NT. However, Easy CD Creator does work well with Windows NT. You may want to consider using that software instead. Visit Adaptec’s web site at http://www.adaptec.com/support/overview/cdrec.html
