Reading RW CD's from Linux

[Mike Barnes]

I created a cd from Adaptec EZ CD Creator on a Windoze machine and on
windows I can read it fine.
But when I tried reading it from my Caldera Linux 2.2 all it saw was a test
file. 

This isn't much of a problem because I have a dual boot machine and can just
transfer it from windows to Linux but still quite irritating considering I
have to reboot into windoze just to read it!
 
Any clues?

BTW what is a .os file in linux??

I know a .o but not .os lol

Thanks :)
