I have followed the guidelines HOWTO add a second harddrive, and it almost works.
I have formatted the drive, made the filesystem and added it by the following line in /etc/fstab:
/dev/hdc1 /home/e-smith/files/primary/files ext2 defaults 1 2
But everytime I connect to my ftp-server (which now should be on the other drive) I get access denied. Make sure disk is not full, or write protected.
