I am curious if anyone can clear up the following phenomena
for gnu tar on testing:

# tar --version
tar (GNU tar) 1.13.25

basically I have  cdrom mounted under a directory 

and i ran 


tar zcvf win2k.tgz /mnt

and

tar zcvf win2k-2.tgz /mnt



Perhaps I should be using different options to get the
same files:


# cmp -version
cmp - GNU diffutils version 2.7


cmp -l on the files yields:

# cmp -l *
     5  35 362
         6   4   2


I also did a dd on the raw device and that at least gave no differences.

I am trying to determine whether the cdrom drive is faulty. Does anyone know
of good ways to test such a thing.
