external hard drive

[Scott Blair]

I am running Ubuntu 14.04. I have 2 eternal hard drives. The one works fine
The second, 3TB, one works half way. It will not show all the files and 
directories on
the hard drive. Sometimes I can't copy any file off of it. Any ideas on 
what causes
this. This just started happening few days ago.

Here is fstab:
# /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>
# / was on /dev/sda6 during installation
UUID=441e546d-2648-4460-a863-81009c22aa5a /               ext4 
errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=2f687164-31bf-41fd-9310-39f785e59a1e none            swap 
sw              0       0


Here is fdisk -l:
