Hi all
I thought this thread was dead after the remarks of someone who thinks the

Still, the cd isn't copy protected. It is, in fact, three years old and has
seen more of the carpet then my vacuum cleaner.
That, and the fact that rented dvd's frequently cause the same problem (even
worse, soundcard stuck in passthru because xine crashed) only emphasises my
original assesment that a bad medium causes real problems with FC.
I have no idea whatsoever as to how the os handles removable media, but it
seems that it is not limited to physical media. For instance, try umounting
an nfs share when the server "sharing" is down.
Bad sectors on media are detected and logged, so how about trying to read
three times, if it still fails, abandon, unlock the volume, and signal the
program that the disk is no longer mounted or is corrupted.
With kind regards

I noticed this problem causing extreme slowdowns and also when it sends
your system off a cliff, no responses at all.
I filed a bug report when there was a kernel version that would cause
corruption frequently. Several different discs would bomb the system.
With the next kernel version, I would not have system crashes.
I'm sure that there is work ongoing to correct this error. There is
probably a lot involved in regards to programs, hardware, the state of
the processor and the like. You can file a bug report against processes
that are effected by this severe limitation that not having a clean exit
from bad media.
Having discussions where knowledgable people know what portions of
programs, hardware limitations can be undertaken to correct the problem.
I know from reading posts in response to my comments that discussions
are not going to go far on this list. The problem is real, but not a
user list discussion issue.
I think your idea is good in regards to letting the system fail the
process gracefully and release the hardware in a practical way.

BTW - The bug I filed is closed. The initial problem does not hamper me
now. Th effects were a bit upsetting though and should not happen ever
again. This is probably utopia dream, but one worth having.
Closed report. Not much chasing to do, unless examining the older kernel.
