Knoppix will not allow me to access my external hard drive and partitions from the internal hard drive. I have looked at the permissions making it say that it's writable but I don't know what's going on. So here is what I'm trying to copy: The entire folder: /media/sda2/home/jeffrey to /media/sdb1/jeffs If you guys can help me out that would rock! Jeff

How are you mounting it exactly? Also, who is uid 100? You can use Code: $ grep 'x:100:' /etc/passwd to find out. How about gid 1000? Code: $ grep 'x:1000:' /etc/group

Here are the commands: knoppix@Knoppix:~$ grep 'x:100:' /etc/passwd mysql:100:103:MySQL Server:/var/lib/mysql:/bin/false knoppix@Knoppix:~$ grep 'x:1000:' /etc/group knoppix:1000:

knoppix@Knoppix:~$ fdisk -l
knoppix@Knoppix:~$ fdisk -l
