Some CD-ROM drives read discs very slowly if Read Ahead capabilities are enabled in Windows 95/98/Me.

Turn off Read Ahead capabilities for the drive.

Windows 95/98/Me only:

1.Click the Start button, select Settings, and click Control Panel.

2.Double-click the System icon.

3.Click the Performance tab on the System Properties dialog box.

4.Click the File System button in the Advanced settings box.

5.Click the CD-ROMtab.

6.Select No read-ahead from the Optimize access pattern for: pull-down box.

7.Click the OK button on the File System Properties dialog box.

8.Click the OK button on the System Properties dialog box.

9.Windows prompts you to restart your computer so that the change can take effect.

If read errors occur when you use the CD-ROM drive to read both commercially- produced CD-ROM discs and CD-R media, the CD-ROM drive or its controller are faulty, the driver for the CD-ROM drive or controller is corrupted, or your Windows installation has become corrupted.

You used CD-RW media

If your CD-ROM drive can read formatted CD-RW discs but the drive lacks the necessary software, you can locate the software in the ENGLISH/UDFREADER directory on the software installation disc.

If the UDF Reader doesn't enable you to read the disc, the CD-ROM drive is probably not Multi-Readcompatible. To make a data disc that is compatible with non-Multi- Read CD-ROM drives, use HP RecordNow and CD-R media.

The CD-ROM drive you are using is probably not Multi-Read compatible. Use CD-R media when you want to read discs using this drive.

If you're trying to read an 80-minute CD

See 80-Minute CDs on page 88.

If these suggestions do not solve the problem, try these possible solutions:

You used CD-R media

Try closing the disc with the HP DLA wizard before reading it with a CD-ROM drive

If closing the disc fails to solve the problem, the CD-ROM drive is probably not Multi- Read compatible. To make a data disc that is compatible with non-Multi-Read CD- ROM drives, use HP RecordNow to write the CD.

(When you close a CD-R disc, you cannot reopen it to add more data with DLA.)

You formatted a disc and copied files to it using drive letter access (Windows Explorer, etc.)

If the CD-ROM drive you are using to read the recorded CD-R disc can successfully read commercially-produced CD-ROM discs, the drive is probably not capable of reading any form of recordable CD media.

A home, auto, or portable stereo CD player cannot play a recorded disc

Make sure this is an audio CD, not a data CD

Home, auto, and portable stereo CD players cannot read data discs.

Use the correct media

Make sure you use CD-R discs for recording, not a CD-RW discs. Most stereo CD players cannot read CD-RW discs. If you used a CD-RW disc, you can easily transfer its contents to a CD-R disc using the "Make an exact copy" feature of the HP RecordNow software. After you copy the CD-RW disc, you can erase and reuse it.

If an error occurs while recording

If HP RecordNow reported a serious error while recording an audio disc, the final state of the disc is uncertain. It may or may not play the audio tracks that had been recorded before the error occurred. Record the audio disc again.
