Buffer I/O error on device ... logical block ...
~
I have some 1980 data on DVDs I would like to back up to a hard drive
~
The data itself is apparently mounted read only and I can access and
see it with no problems
~
The thing is that when I try to copy it to my hard drive large files
are not being copied (only smaller ones) and this is what I see when I
run dmesg
