Hi,

I upgraded my system from RedHat 6.2 to 7.0 recently. Among many, I have
the following problem.
One some CDs, I can't read all of the contents of the CD. This is the case
for instance with the SimCity 3000 Unlimited CD for Linux, where I can't
read the executable files under bin/x86/glibc-2.1. Here is what I get:

[root@destroy /cdwr]# ls -l /mnt/cdrom/bin/x86/glibc-2.1/
total 13423
dr-xr-xr-x    2 root     root         6144 Aug 12 03:26 lib
-r-xr-xr-x    1 root     root      6910500 Aug 12 03:25 sc3bat
-r-xr-xr-x    1 root     root      6798217 Aug 22 20:56 sc3u
[root@destroy /cdwr]# file /mnt/cdrom/bin/x86/glibc-2.1/sc3u 
/mnt/cdrom/bin/x86/glibc-2.1/sc3u: file: read failed (Input/output error).


First I though maybe the disk itself is bad, or the CD drive has problems.
But I can read up the whole CD image with dd without any problems, mount it
via the loop device, and still get the same error. Needless to say, the CD
can be read without problems on a RedHat 6.2 machine.
