I just installed Win98SE on a newly constructed P4 computer (Intel
D845BG board).  Other than 98, here is minimal software
installed...video drivers, etc.

The CD-R, re-used from another (personal) machine, is constantly
recognizing every CD (data, game, install) inserted as a an AUDIO
CD....File Explorer shows one "audio file"....  True audio CDs show
ALL the song tracks.

I'm sure this is a Windows setting as the drive functioned perfectly
in the other machine...

Any ideas?  I'd like to install some stuff on this machine...  Wah!

Hi there,

If you have written a CD-R as a multisession disc then you will need
to follow the instructions here to remedy the problem:

This page provides some solutions for fixing the exact problem you are

From the address above:
"Subject: [4-37] I inserted a CD-ROM but Windows thinks it's an audio
CD
(2002/03/18)
Sometimes a Windows system will get into a state where it thinks that
a CD-R or CD-RW data disc is an audio CD. This is very peculiar, since
the CD-ROMs aren't "enhanced" discs with both audio and data content.
In some cases the problem only happens with a CD recorder -- a CD-ROM
drive in the same machine will work correctly -- or vice-versa.

One situation where this is reported to occur is with a JVC XR-W2080
with v2.06 firmware (or an equivalent OEM version). If you have the
Roxio UDF reader loaded, whether manually or as part of installing
DirectCD 3.x, the problem will occur. Removing the UDF reader, either
with Add/Remove Programs or renaming
\Windows\System\Iosubsys\Udfreadr.vxd, is said to fix the problem.

Another occurrence has been reported with Toast 3.7 on a Mac. If a
disc was recorded with Toast as CD-ROM/XA instead of CD-ROM, Win98
would see the disc as audio. Win95 and WinNT worked fine on the same
disc.

One user found that replacing the IDE cable made the problem go away.
Another found that using MODE-1 rather than MODE-2 helped (check the
advanced recording options in your software).

Another user got the problem to go away by uninstalling "Wavelab". 

Somebody else found that the problem went away on a SCSI device when
he disabled wide negotiation and limited the data rate to 16MB/sec. "

If this doesn't do the trick, here is a personal suggestion:
1. Check to see if your CD-ROM drive came with any of its own drivers.
2. If so install them so that they wipe out the one that windows
probably installed automatically when WIN98 was installed.
(Sometimes the windows drivers are too general since they try to cover
multiple hardware pieces with a single driver. This often results in
devices that work, but not to full capability. The driver included
with the device is always recommended)

You can get the most up to date UDF reader from here:

CD-R that may interest you:

Great answer.  Have not tried to fix the drive yet, but it's worth $5
to hear from someone who is brilliantly intelligent.  Lots of good
leads here for me to follow-up.
