Troubleshooting - Writing Discs. TDK Velocd | Manualzz

SYMPTOMS

Cannot write to CD-R or

CD-RW disc.

CD-R or CD-RW software cannot detect veloCD.

TROUBLESHOOTING : Writing Discs

CAUSES

1. You are using authoring software other than that bundled with your veloCD.

2. CD-R or CD-RW media is not supported.

SOLUTIONS

1. Use the authoring software provided with the veloCD.

To use other types of authoring software, contact the supplier and ensure the software supports the veloCD CD-RW drive. Supported software lists can also be found on the TDK web site at www.velocd.tdk.com.

2. Use CD-R or CD-RW media recommended by TDK in the

Appendix.

3. Disc inserted upside down.

4. Lack of hard drive capacity.

This varies with different software packages. Contact the software vendor or check their documentation for recommendations.

1. Power connector is not attached to veloCD.

3. Eject the disc from tray and load it with the label side up.

4. Delete files from your hard drive to free up sufficient space; or use another hard drive.

2. IDE cable isn’t connected properly.

3. Drive or IDE bus is not enabled in the computer’s BIOS.

4. Jumper conflict.

1. Ensure the computer’s power cable is securely attached to the veloCD’s power connector.

When the computer’s power is turned ON, confirm that the veloCD’s indicator LED is illuminated briefly, then is extinguished.

Try connecting another power cable to the veloCD.

2. Ensure that the IDE cable is securely inserted, and is not damaged. Check the connector pins to ensure they are not bent.

3. Ensure the IDE port is enabled and set properly in motherboard’s

BIOS. See "Make Sure the Drive

Is Recognized" on page 13 for more details.

4. Check jumpers for the veloCD drive and the other peripheral devices (hard drive or CD-ROM drive) on the same IDE cable.

Ensure the jumper for one device is set to Master and the other to

Slave. Two devices on one cable cannot be set to the same setting.

CAUSES

5. Wrong cable with jumper set to

Cable Select.

SOLUTIONS

5. Make sure that a CSEL compatible IDE cable is used if you want to use the veloCD with jumper set to Cable Select.

Writing error occurs.

Buffer underrun.

Does not record at max speed.

1. DMA is not enabled on your computer.

1. In Windows 95/98/ME, click on

Start button, then select Settings/

Control Panel, then double-click on System icon, then click on

Device Manager tab, then doubleclick on CD-ROM icon. Select veloCD and click on Properties.

Then click on the Settings tab and enable DMA. Reboot your system.

Make sure DMA is enabled on your motherboard.

2. Network is being used.

Mouse was moved or Windows screensaver activated while writing.

Other applications are running.

Power save mode is active.

2. If problems occur when writing, reduce the load on CPU resources.

Some ways to do this are:

Log off from the network.

Don’t use the mouse.

Disable the screensaver or

power save mode.

Exit all other applications.

3. Shortage of PC memory. If there is insufficient main memory in the PC, data may be swapped to the hard drive, and this can cause a buffer underrun.

4. VeloCD and other IDE CD-ROM drive are connected on the same cable.

5. VeloCD and hard drive are connected on the same cable.

6. Automatic thermal recalibration triggered. Some high-speed hard drives are equipped with an automatic thermal recalibration function.

3. Increase the PC’s main memory capacity.

4. When writing from another

IDE device to the veloCD on the same bus using on-the-fly writing, the IDE bus is very busy and it may cause writing errors.

This depends on your system speed and configuration. Use the image writing method for best results (safe mode) or record at lower speed.

Put the IDE CD-ROM drive on the primary bus and veloCD as the only device on the secondary bus (Master).

5. Remove the veloCD from the cable and re-connect it to a secondary

IDE port.

6. Use another hard drive in this case.

dirty , scratched, or damaged.

8. Buffer underrun option is not

enabled in your software.

SOLUTIONS

7.ReWrite using another CD-R or

CD-RW disc.

8. Ensure that the buffer underrun

option is enabled in the recording menu before you write to your media.

Cannot add information to CD-R or CD-RW disc.

Cannot write at max speed.

1.The CD-R or CD-RW disc was

originally written using other

software. If the software is

different, incompatibility errors

may occur.

2.Not enough disc capacity.

Capacity of a standard 74-min.

CD is limited to 650 MB.

Capacity of an 80-min. CD

is limited to 700 MB.

3.The disc is written on with a

CD-R or CD-RW drive from

another vendor .

1.Always use the same authoring

software to add content to a disc.

2.Use different CD-R or CD-RW

media if the capacity is insufficient.

3.Use a different CD-R or

CD-RW disc. T ry to use same drive

to add more data to CD-R or

CD-RW disc.

1.Using poor quality media.

2.Buffer underrun occurring.

1.Use the CD-R/RW media

recommended by TDK. Supported

media lists can be found in

the Appendix.

2.Reduce the load on CPU resources.

Some ways to do this are:

Log off from the network.

Don’t use the mouse.

• Disable the screen saver or

power save mode.

Quit all other applications

except the authoring software.

FREQUENTLY ASKED QUESTIONS

If you have problems during or right after installation of your veloCD drive, use these tips to help find the problem.

What media should I use for my veloCD ReWRITER?

See the Appendix.

When can I use CD-RW media?

CD-RW media is recordable only in ReWritable drives, and readable only in ReWritable drives or newer

MultiRead CD-ROMs. With CD-RW media you can:

Use as if it were a large capacity floppy disc.

Transport files to and from work.

Copy your important data periodically.

Store large projects as you develop them.

When should I use CD-R media?

CD-R media can be read in most CD-ROM or CD-Recordable drives. Use CD-R media to:

Permanently archive important data.

Copy your music to CD for personal use.

Share non-editable presentations.

Why can't I do disc-to-disc copying?

Some possible reasons are:

Some CD-ROM drives will not allow direct copying to the veloCD ReWRITER or are not capable of

• digital audio extraction.

You must have either a SCSI-2 CD-ROM drive or a supported ATAPI CD-ROM drive to use as

• your source.

Some CDs have a copy prevention feature or other features that do not allow a CD-to-CD copy.

Why am I getting buffer underrun errors?

Usually the “buffer underrun write assurance” option is not selected in your software. Recording CDs requires an uninterrupted stream of data to be supplied from the source device. A buffer underrun occurs when for some reason the data stream is interrupted. This can occur if another application interrupts the writing process, or if the recording drive’s write speed is set too high for the speed at which the source drive can supply data. Lack of computer memory, which causes the computer to swap data to the hard drive, can also cause underrun errors.

veloCD ReWRITER : User’s Manual

Any hints for optimizing the burn process?

Make sure your system meets the minimum system requirements.

Do not run other applications while recording CDs. Log off any networks, disable any FAX modems, email, screen savers, or other programs that may send messages to your computer while it is writing a disc.

If your computer has a power management feature, disable it.

In Windows, run ScanDisk and Disk Defragmenter periodically on your hard drive.

Do not record using data from a compressed hard drive. Buffer underruns may be caused by hard drive compression software.

How do I install the veloCD if I have a DVD drive?

When installing the veloCD ReWRITER in a PC that already has a DVD drive, it may be required that your DVD drive be set to the master jumper position and the veloCD ReWRITER be set to the slave jumper position

What is the best way to label a disc that I just burned?

The best labeling is done with a CD marking pen.

Another way is to use a good quality label maker - this way is not recommended
