How to mount directory on drive 2 to directory on drive 1.


Hi all.
I am running linux mint 18.2 on a dell inspiron 7737 with the dvd drive removed and a hard drive in it's place.
+++++++++++++++++++++++++++++++++++
output of sudo blkid
Code:
/dev/sda1: UUID="6C63-B389" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="31adb522-6ece-4c31-9dd2-e02f7d36fa33"
/dev/sda2: UUID="26f2af11-1d92-4c66-ad9b-99031075b935" TYPE="ext4" PARTUUID="27b2cdf2-fa89-4802-b324-18830e8b8602"
/dev/sda3: UUID="e4f3aef1-bb8a-4a73-a553-6a17c1f59949" TYPE="swap" PARTUUID="f9fa25ca-ad4a-41bf-9de2-d32788976740"

++++++++++++++++++++++++++++++++++++
sda1,sda2,sda3 are all on the boot ssd.
sdb2 is a 1TB spinning hard drive in the dvd bay.

In the root on the 1TB drive I have Documents, Music, Downloads, ETC.

on the boot SSD i have my home directory, I would like to mount the Documents dir on drive 2 to my home Documents.

here is my fstab file anytime I uncomment any of these lines the computer refuses to boot until I comment them out.
I don't understand why please help.

FSTAB
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

If you want to mount a directory (i.e., part of a filesystem) on another directory, you need to use the "bind" mount option.
Code:
/mnt/82aba9ed-4882-511c-0976-123de4efea97/Music /home/area/Music none bind 0 0
You're not mounting a whole filesystem, so you want "none" for the filesystem type.

First of all Thank you rknichols you led me in the right direction.

to get this to work I had to first mount the second hard drive like this.

Code:
/dev/disk/by-uuid/82aba9ed-4882-511c-0976-123de4efea97 /mnt/82aba9ed-4882-511c-0976-123de4efea97 ext4 nosuid,nodev,nofail,x-gvfs-show,x-gvfs-name=Disk2 0 0
Mint > Preferences > Disks
Select the disk > Select the partition on the disk > Gear icon > Edit mount options.
Set Automatic mount options to Off
Select Mount at startup
Give it a Display name (I don't know if this did anything)
Change the file system to ext4 (Again I don't know if this did anything)
reload fstab with
Code:
sudo mount -a
edit fstab to add one line for each directory.
Code:
/mnt/82aba9ed-4882-511c-0976-123de4efea97/Music /home/area/Music none bind 0 0
Thank you, Ondoho and rknichols.
