Hello,
Please find below the content of the file broken-files.txt after running
the following command from a konsole when running the Knoppix 7.0 Live DVD: "sudo tar cf - /KNOPPIX/ 2> broken-files.txt | dd of=/dev/null"

tar: Removing leading `/' from member names
tar: /KNOPPIX/dev/log: socket ignored
tar: /KNOPPIX/usr/amd64-mingw32msvc/bin/strip: Read error at byte 0, while reading 2560 bytes: Input/output error
tar: /KNOPPIX/usr/bin/amd64-mingw32msvc-strings: File shrank by 65932 bytes; padding with zeros
tar: /KNOPPIX/usr/bin/amd64-mingw32msvc-strip: Read error at byte 0, while reading 2560 bytes: Input/output error
tar: /KNOPPIX/var/run/samba/winbindd_privileged/pipe: socket ignored
tar: Exiting with failure status due to previous errors

Interestingly copying the same DVD content from a Windows 7 machine to a hdd does not create any error and
running the same command within a virtual machine using the iso created from the DVD gives the exact same errors:

knoppix@Microknoppix:~$ sudo tar cf - /KNOPPIX/ 2> broken-files.txt | dd of=/dev/null

Please find below the link to the md5 file of the /KNOPPIX content using the following command (skipping the /KNOPPIX/dev directory):
sudo find /KNOPPIX/ | grep -v /dev | xargs md5sum >> knoppix.md5
