I am having a few problems with a CD that I burnt. On this CD there are some Linux drivers but when I try to run them in Ubuntu I keep getting an error so I have tried to extract them under my mac and then transfer them across. Now I get one of the files to show up but the other two are missing. When I go into terminal and use the ls command I can see the files. When I use the cp command to try and copy them across to a new directory it again produces an error. Any suggestion? Thanks.
