Can you confirm that the archive is really ok?

Code:

md5sum /mnt/*.gz

And then compare that output with the same command run on copies of the files that you know are ok.

When I am running md5sum /mnt/*.gz,I get Input/output error.
And if I want to copy /mnt/*.gz to a desktop location ,will get Input/output error.also

Sounds like the cdrom was not mounted properly, or has very serious problems. I Noticed that you did not pass any options to mount: so I wonder what the /mnt line in your /etc/fstab looks like. Can you please post the output of the following?

Code:

ls -al /mnt
file /mnt/*
grep mnt /etc/fstab
mount | grep mnt

The output you show in post #8 seems to indicate that the cdrom is mounted ok. In particular 'file /mnt/*' gives no errors. Are you able to read or copy the file /mnt/manifest.txt? Or do you get i/o errors like with file.tar.gz?

Are you able to read or copy the file /mnt/manifest.txt?
-->Yes,I can

Or do you get i/o errors like with file.tar.gz?
-->Yes,When I want to copy /mnt/file.tar.gz to a local location ,will get Input/output error.

evo2 · 03-02-2010, 11:46 PM

Ok so manifest.txt seem to be ok, but file.tar.gz is not. I think you need to reburn file.tar.gz to a new cdrom.
