This article is from the CD-Recordable FAQ, by Andy McFadden (firstname.lastname@example.org) with numerous contributions by others.
This problem is often experienced by HP7100/7110 users. HP chose to ship
packet-writing software with their drives rather than conventional
premastering software, leaving users with discs that couldn't be read on a
fair number of systems. (The HP7200 is the same drive, shipped with
updated firmware and a more complete set of software.)
The following is an excerpt from an Adaptec readme.txt file. It talks
about DirectCD, but the problem is inherent in all packet writing
"When the disc is in the native format used by DirectCD, you will
only be able to read the disc on a CD-R device running DirectCD.
This is a direct result of the technology used when writing to a
CD-R disc. In order to make the disc readable on a standard CD-ROM
DirectCD must write certain data to the disc. This provides
compatibility with many of the current drives on the market today.
Unfortunately, there are still a number of CD-ROM drives that
cannot read the packet written media that DirectCD produces. If
you experience problems in this area, you should go to System in
Control Panel, select Performance, File System, CD-ROM and set the
Access Pattern to "No Read-Ahead". If you still experience
problems after making this adjustment, it is likely that the CD-
ROM drive itself is having problems reading packet written media.
It should also be noted that there is an industry initiative
called MultiRead that addresses these issues and has the support
of all the major vendors of CD-ROM and CD-R/RW devices. This
initiative will eliminate the above problems and should be
available on all new drives."
If you want to share data between systems, and the remote system isn't
guaranteed to have a MultiRead CD-ROM drive, you should write the disc
with conventional software.
