A co-worker created a data CD on a CD-RW disc at another
instituion. The files on the disc can read from some CD-
ROM drives and not others. All machines are running Win2k
sp3.

On machines where the files cannot be read, the 3 folders
on the disc show in the Windows Explorer but when a folder
is selected the Explorer indicates that there are 0
objects in the folder using 0 bytes of space. On these
machines, there also appears at the root level of the disc
directory a generic Windows icon labeled 'non-allocatable
list'. It contains 0 bytes.

On machines where the files can be read you see only the 3
folders at the root level and each folder contains data
files.

Not sure if it is a hardware or software problem. It's as
if the problem CD-ROM drives cannot access the tracks
where the 'file allocation tables' have been written.

Is anybody familiar with this problem? Please enlighten
me.

Hard to tell with out playing around with it some more. Expedient
solution is to copy the CD at a station it can be read at, and recreate
the CD with a burner and software that isn't a mystery.

She may have created it with Direct CD or InCD (UDF packet software)
depending on which software she used (Roxio or Nero). In order to read
these files on a computer without these installed, you need to download and
install the reader software
http://download.com.com/3000-2100-94...ml?tag=lst-0-1 for Direct CD or
http://www.nero.com/en/631977199298978.html for InCD.

Also, some older CD-ROMs will not read CDRs or CDRWs at all or unless they
are closed and CDRWs are not usually closed (finalized).
