Chapter 3:

Problem Solving

Read this section if you run into trouble with your CD-Writer Plus drive.

If after reviewing the section you need further assistance, call the phone numbers listed in “Appendix B: Customer Support”

Gather the information on page B-1 before calling for help. Having this information ready will greatly facilitate your call.

Things to Try First

Does your computer meet the minimum system requirements

(see“Minimum System Requirements” on page A-1 )?

Make sure your computer and CD-Writer Plus drive are plugged in and that each device attached to your computer is turned on.

Turn off the computer’s power, unplug the CD-Writer Plus drive, and wait 20 seconds. Then plug in the CD-Writer Plus drive and turn on your computer. (This is called cycling power.)

Disconnect all the cables and then reconnect them. Sometimes just reconnecting a cable aligns it correctly or adjusts the pin connections, fixing a faulty connection. (Check for bent pins on the connectors and straighten them.)

Make sure that you are using the right type of CD. See “Choosing CDs for Your CD-Writer” on page 2-2.

Try the operation with a different CD.

Check the list of known compatibility problems (page 3-7) and in the

Readme file.

3-1

3-2 Common Symptoms and Solutions

If your computer has a power-management feature, disable it (see the manual that came with your computer).

If your system is running printer status monitor software, disable it

(page 3-7).

Make sure that you are not attaching a parallel port switch box anywhere in the CD-Writer Plus drive’s cabling configuration.

Common Symptoms and Solutions

Copying directly from one CD to another doesn’t work.

WARNING: Only reproduce material for which you own the copyright or have obtained permission to copy from the copyright owner. Unless you own the copyright or have permission to copy from the copyright owner, you may be violating copyright law and be subject to payment of damages and other remedies. If you are uncertain about your rights, contact your legal advisor.

Some CD-ROMs will not allow direct copying to the CD-Writer Plus drive or are not capable of digital audio extraction.

You must have either a SCSI 2 CD-ROM drive (see the drive’s guide for information) or a supported ATAPI CD-ROM drive as your source.

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

Audio sounds poor

■ If your printer is attached to the CD-Writer Plus drive, printing documents while playing audio CDs will yield unpredictable results and is not a supported CD-Writer Plus drive function. This is because the printer and CD-Writer Plus drive are sharing the same data cable.

Make sure the audio connectors are completely plugged in to the back of the CD-Writer Plus drive and the LINE IN connector of the sound card on the back of the computer. (Your sound board may be labeled differently.)

Verify that you do not have a sound-muting feature turned on, by way of the monitor or software.

Check the sound coming from the CD-Writer Plus drive by plugging earphones or speakers to the audio connector on the front of the CD-

Writer Plus drive. If the sound quality is good, the problem is probably with the sound board, speakers, or audio cable. Refer to the documentation that came with your sound board and speakers for help. If you are not already doing so, try using the audio cable that came with the CD-Writer Plus drive.

Try listening to the wave files on your hard drive to see if they sounded poor before copying them to CD. (You can use the Media

Player program found under Multimedia in Windows’ Accessories.)

3-4 Common Symptoms and Solutions

Video is choppy

This can be caused by the same situations that cause buffer underruns.

This can also happen if your video card is slow. Try the following:

Try the solutions for buffer underruns (page 3-4).

Reduce the size of the video window and close any other programs that are running.

If the previous suggestions don’t work you may want to consider upgrading your video card.

Buffer underrun error messages

CD recordable devices require an uninterrupted data stream from the hard drive in order to write successfully to a CD. A buffer underrun message appears when for some reason the data stream is interrupted.

This can occur, for example, if another application interrupts the writing process, or if the CD-Writer Plus drive’s write speed is set too high for the speed at which the hard drive can accesses and transfer data.

When using Easy-CD Creator or CD Copier:

Make sure you use the Test option in the software to ensure that the write speed is appropriate for your computer. For more information see the application’s online help.

Make sure your system meets the minimum system requirements

(page A-1).

Buffer underrun may be caused by hard drive compression software

(page 3-7).

NEVER write to the recordable CD while other applications are running that could interrupt the writing-to-CD process. Log off any networks, disable any fax modem, email, screen saver, or other programs (such as TSRs, terminate-and-stay-resident programs) that may automatically send messages to your computer while writing data to the CD. If the interruption is long enough, you could ruin a write-once CD to which you are writing.

Exit any other programs while writing data to the CD.

If your computer has a power-management feature, disable it (see the manual that came with your computer).

■ Run SCANDISK.EXE and DEFRAG.EXE periodically on your hard drive (see your Windows manual for more information). These

Common Symptoms and Solutions 3-5

■ programs improve access times to the hard drive, which will help improve system performance while writing to and reading from the

CD-Writer Plus drive.

A small number of older hard drives are designed with a built-in interrupt loop that may cause a buffer underrun. If you are unable to resolve buffer underruns by any other means, contact your hard drive manufacturer to find out if this is the case for your hard drive.

Buffer underruns could also be caused by an unsupported parallel port

(standard mode SPP). See “Minimum System Requirements” on page A-

1. Try the following:

Write data to the CD at 1x speed if you are given the choice within the software.

Disable any printer status monitor software (page 3-7).

Change the parallel port settings to EPP or ECP in CMOS, if your computer can support the change. See the manual that came with your computer to find out how.

If the previous suggestions don’t work you may want to consider installing a new EPP or ECP parallel port card.

Unable to read a second session reading from a CD-ROM drive

Eject the CD and reinsert it.

Refresh the screen. Select the My Computer icon in Windows

Explorer and press F5.

CD-RW (ReWritable) discs can only be used in CD-ReWritable drives or newer MultiRead CD-ROMs.

If you are trying to read your CD from Windows 3.x: Multi-session CDs created with Direct CD cannot be read in DOS or Windows 3.x. If your multi-session CD was created using some other program, verify that you are using version 2.23 of the MSCDEX.EXE file. First, restart your computer and when you see “Starting MS-DOS...” appear on your monitor, press F8. Each line in your CONFIG.SYS and

AUTOEXEC.BAT file will load one at a time. Press “Y” until you see a line containing “MSCDEX.EXE”. Then press “Y” and the version number of your MSCDEX file will display. The number must be 2.23 or greater. Call Microsoft for an updated file if you need it.

See if the CD-Writer Plus drive or other CD-ROM drives can read the

CD. If so, the problem is probably with the CD-ROM drive. Contact the manufacturer of this drive for updated drivers.

3-6 Common Symptoms and Solutions

Applications cannot find your CD in the CD-Writer Plus drive

Some programs (CD-ROM games, etc.) look only for the first logical drive letter assigned to a CD-ROM drive or CD-Writer Plus drive. For example, if your CD-ROM drive is assigned drive D:\ and the CD-Writer Plus drive is assigned drive E:\, the program is looking for the CD only in drive D:\ and will not see the CD in drive E:\. If you want to use the CD-Writer

Plus drive for these types of programs, reassign the drive letters, making the CD-Writer Plus drive come before the CD-ROM drive, as follows:

In Windows 95 or Windows 98, display the Device Manager and double-click on CDROM. Double-click on the CD-ROM drive, and then click on the Settings tab. Under Reserved drive letters, select the drive letter after the existing letter (for both start and end drive letter) and click on OK. Then double-click on the CD-Writer Plus drive, and then click on the Settings tab. Under Reserved drive letters, select the drive letter before the current one and click on OK.

In Windows NT, click on Start/Programs/Administrative

Tools(common). Choose Disk Administrator. Right-click on the drive letter you wish to change. Select Assign Drive Letter. Change the drive letter.

Lost power to your computer or had to press CTRL-ALT-DEL while writing to the CD!

If you lose power while writing to your CD (the CD-Writer Plus drive's red light is on) OR If you exit an application or press CTRL-ALT-DEL while writing to CD...

You may be able to salvage your CD, but ONLY if you:

1. LEAVE YOUR CD IN THE DRIVE, DO NOT OPEN THE DISC TRAY

2. Turn your machine off

3. Turn it back on

4. Then re-enter the application you were using

Once the application tries to access the CD-Writer Plus drive, the recovery operation will make it appear that the last session is there.

However, in reality, only a part of the CD's directory may be there. Your recordable CD is still usable if you can read the directory. Repeat the entire copy operation to make sure that your files are copied to the recordable or ReWritable CD.

Common Symptoms and Solutions 3-7

Hard Drive Compression Software

We do not recommend using hard drive compression software. If you use hard drive compression software, it estimates free hard drive space based upon a compression ratio (often user selectable). Programs may check your hard drive for space needed and may think you have the necessary free space. However, depending on the type of files you are copying, you may in fact not have enough hard drive space.

Achieving optimal performance

Run SCANDISK.EXE and DEFRAG.EXE on your hard drive before using your CD-Writer Plus drive for the first time (see your Windows manual for more information). Then run them periodically after that. These programs improve access times to the hard drive, which will help improve system performance while writing to and reading from the CD-

Writer Plus drive.

Printer Status Monitor Software

NOTE: This is only an issue if your printer is connected to the back of the CD-

Writer Plus drive.

If your printer came with a program that notifies you about the status of the printer (such as when it is out of paper), this printer status monitor software might cause problems. The printer status monitor software checks the status of your printer every few seconds. If this happens while you are writing data to your recordable CD, it will cause data corruption. Turn off the printer status monitor software to prevent this problem. Check the information that came with your printer to find out how to do this.

Known Compatibility Problems

■ Check the Readme file that came with the CD-Writer Plus drive for additional information. Click on Start, then point to Programs, HP

CD-Writer Plus, Tools and Information, User Reference then click

README.TXT.

Check the HP web site listed on page B-4 for the most recent information.

Printers in General

If your printer came with a program that notifies you about the status of the printer (such as when it is out of paper), this printer status

monitor software might cause problems. The printer status monitor software checks the status of your printer every few seconds. If this happens while you are writing data to your recordable CD with the

3-8 Common Symptoms and Solutions

Easy-CD Audio or CD Copier software, it will cause data corruption.

Turn off the printer status monitor software to prevent this problem.

Check the information that came with your printer to find out how to do this.

Finding the CD-Writer Plus driver files.

In Window 95/98, the following file is needed for your CD-Writer Plus drive to work successfully attached to a parallel port:

EPATAP9X.MPD (mini port driver file)

This file will be copied from Software Disc 1 during installation and located in the \WINDOWS\SYSTEM\IOSUBSYS\ directory.

In Window NT, the following files are needed for your CD-Writer Plus drive to work successfully attached to a parallel port:

EPATAPNT.MPD (mini port driver file)

SHARSHTL.SYS (printer driver support file)

These files will be copied from Software Disc 1 during installation and located in the \WINNT\SYSTEM32\DRIVERS\ directory.
