Default CD reading problems

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

No clue, but maybe check some of these?

Gary,
Thanks for the speedy reply. Your suggestion did not give a result on
launchpad. The strange thing is that I get regularly ata1 errors (which
show up in my daily logs) but current kernels use scsi as indication of
disks and the HD's on this system are SATA (1 internal 2 external). The
CD-writer (Samsung SH-223) is also SATA so I don't understand the error.
But I solved it by copying the CD to an USB-stick and read it on the
target system. Not a solution for the problem but a circumvention.

Due to time differences (I assume 8 hours) You read my mail when you're
awake as I wrote it late at night (~ 1 AM) and I read your mail I
presume when you sleep| but at us at least much faster than snail mail.

Gary, thanks again,
Joep

Do you get any other errors when you:

$ grep -e 'sr0' -e 'ata3' /var/log/messages
or
$ grep -e 'sr0' -e 'ata1' /var/log/messages

Gary,
Yes, both give a lot of messages and especially the 2nd line you gave
showed a lot of messages but most are:
Sep 10 20:07:00 Laguna-new kernel: [1149587.927797] ata1: EH complete
Sep 10 20:07:00 Laguna-new kernel: [1149590.371857] ata1.00: configured
for UDMA/133
....
and also
Sep 9 20:06:55 Laguna-new kernel: [1063190.823830] ata1.00: qc timeout
(cmd 0x2f)
Sep 9 20:06:55 Laguna-new kernel: [1063190.823962] ata1: hard resetting
link
Sep 9 20:06:56 Laguna-new kernel: [1063191.350047] ata1: SATA link up
3.0 Gbps (SStatus 123 SControl 300)
Sep 9 20:06:56 Laguna-new kernel: [1063191.378690] ata1.00: configured
for UDMA/133
Sep 9 20:06:56 Laguna-new kernel: [1063191.378735] ata1: EH complete
.....
But I think they are messages and not errors but my knowledge of the
modern kernel way of coping with modern HD's is minimal. In the old days
(DOS and 286 processores) I could tinker with read an write times etc
to optimize performance but nowadays I have no idea how it is implemented.
I don't think it is an indication of imminent HD failure but I'm not
sure of it.
Joep
