What do you mean by "givving myself root permissions?"
Because you did not give any details on what you did exactly I will show you how I do this:
Code:
in /etc/fstab I have following line
/dev/sda2 /mnt/BIG_DISK auto rw,user,noauto 0 0
Then:
Code:
su - {give password}
mount /mnt/BIG_DISK
cd /mnt/BIG_DISK
mkdir USER_DIR
chown username.users USER_DIR
Or something similar.
This works.
If you still have problems you must give more detail in what you did exactly,
what mount parameters did you use, and such things.
