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.
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.

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-Read compatible. 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.

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.
