CD reading problems

[Joep L. Blom]

I have an odd problem.
I bought a new laserprinter (Samsung ML2580) which comes with a CD 
containing a.o. drivers for Linux(!).
However, I cannot read the CD with ubuntu 9.10 (on 2 different systems) 
but I can read it with an ubuntu 8.04 system (and of course Windows).
To check if it was an hardware problem, I tested it with a CD containing 
a large Windows program. That CD could be read so it's not a hardware 
problem.
In the message log I find:
ata1.00: configured for UDMA/133
Sep  9 15:16:31 [1045766.078936] ata1: EH complete
Sep  9 15:29:08 [1046523.145899] VFS: Can't find a valid FAT filesystem 
on dev sr0.
HAs anybody a clue where to look for asolution?
Thanks in advance,
Joep
