Automatic Mount at Boot For Xubuntu

I'm trying to follow these instruction to mount a second hard drive: https://help.ubuntu.com/community/InstallingANewHardDrive For automatic mount at boot it says I need to enter this into the terminal: sudo nano -Bw /etc/fstab Then: Add this line to the end (for ext3 file system): /dev/sdb1 /media/mynewdrive ext3 defaults 0 2 Add this line to the end (for fat32 file system): /dev/sdb1 /media/mynewdrive vfat defaults 0 2 I'm not really sure what file system I am working with. I'm also not sure what it means to add the line to the end. End of what? This is a screen shot of what happens when I type in "sudo nano -Bw /etc/fstab"
