A:

you need to edit your /etc/fstab file in order too mount the external hard drive partition on boot.
To do this type the following: 
You need to get the UUID of your external hdd, type:
sudo blkid /dev/sda4

copy the line UUID="some-long-number"
now unmount the disk and make a folder to mount it in the future:
sudo umount /dev/sda4

then:
sudo mkdir /media/almacén

now type:
sudo nano /etc/fstab

and go to the end of the page using your arrow keys.
now copy&paste the following 
#external hard drive almacén was on /dev/sda4 at the time of writing.
UUID=some-long-number  /media/almacén       auto        defaults        0     2

where UUID=some-long-number is the UUID you got from the 'blkid' command earlier
 (BUT WITHOUT THE " " )
Shutdown your computer, plug the external hdd back in and restart.
Your drive partition 'almacén' should now be mounted on '/media/almacén' on login.
