It's definitely a data DVD of some type, then.

The strings in the file say that it was supposed to be UDF.  However, if you
try to mount it as UDF, it says something like "can't find a superblock at the
end of the image".  If it's supposed to be UDF, then the first thing I'd try
is to dd the whole thing to a file, then run fsck.udf on that file, and see if
that can reconstruct the superblock or at least make the first few VOB files
readable.  Note that the fsck you need may be called udffsck, and it might not
be installed.  The fsck for UDF should be available on all distros.

It may also be that it was burned as a multisession DVD and never fixated, or
it had 2 sessions and the second session was messed up.  "cdrecord -toc
dev=/dev/scd0" will tell you how many sessions it has.

If the DVD is damaged at the very edge, where the fs said it was looking for
the superblock, or there's multisession oddness going on, that could cause the
problems you reported.

Re: Helping a Japanese Ftiend

[Dazed_75]

Thanks Matt,

Sorry for the delay, yesterday was nuts.  I was able to "dd if=/dev/sr0
of=/dev/null bs=1M count=5" as you suggested so I did the whole thing with
of=japanese.iso and tried mounting that with Archive Mounter with no
success and the with Archive Manager which gave me an error that it was not
an iso0660 format.  Lastly I used hd some of it to a file (attached) if
anyone wants to see it.

I'm going to have her try to get some details from her brother about how he
made it.  I doubt that she will be able to.

Re: why /var/log/messages went crazy?

[Michael Butash]

Things like that have always been hardware or acpi/bios errors for me, 
basically power management is broken.  You can remove whatever hardware 
you can (or disable it at a bios level), and try looking for a bios 
upgrade.  Maybe force APM mode and/or disable ACPI as JD said via kernel 
or bios.  Likely it won't be fixed by the vendor, as few, especially but 
a few years ago cared about linux enough to bother.  They usually fix it 
as a "driver" to windoze (sadly windoze probably works around crap 
hardware more), and call it *good enough*.


My hp has acpi errors like this (breaking suspend, various other 
shutdown problems under linux), where hp even said in a forum it's not 
worth their time to fix the bios with so little users reporting it a 
problem.  Boo hp, dell on the other hand will test/qualify/fix for linux 
on laptops and most hardware.  I won't buy or recommend hp laptops again.

What I found helped out was going into my BIOS settings at boot-up time
with F11. Then going into the Power tab and disabling ACPI. Then I still
get about 10 errors like the one above when I startup, but at least its
not the constant log filling that was happening before. I found some
documentation listing the BIOS in the SR1700 series of Compaqs as broken.

Several days ago, my /var/log/messages (and syslog and user.log) went

Thanks to help from plug and another forum, I was able to delete enough
files to regain enough file space to get the system restarted, and I
then
flushed the overloaded error message files and for several days, no
messages were added in /var/log/messages , syslog, and user.log for
about
a week. I was checking for new messages every day or two and all
seemed to
be okay until today, something caused the /var/log/messages and syslog
files to start filling up rapidly again.  This time I saved 1,000 of the
most recent entries in the messages file (several thousand messages were
added today), shut the system down, and rebooted.  After that, the
messages and syslog files slowed down to a trickle ... but how can I
figure out what is causing a flare-up like this?

I've posted the last 1,000 entries at this link:
http://www.upquick.com/temp/messages.last1000

As you can see, messages were being added at a rate of 15 to 20 per
second
before I shut the system down.  After reboot, messages were only added
every couple of minutes or so.

Can anyone please tell me what might be causing these message flare-ups
and how to stop it.
