Mounting a new hard drive

  • 772

I installed a new hard drive that will be used for additional storage only. I have followed these instructions on Ubuntu pages to partition it, but when I follow the instructions to automatically mount it, I get lost. It tells me to enter a new line in fstab but when I enter the line, there is no way to press enter and confirm. I also see it says something about using uuid but that link is no help either.

The output of sudo fdisk -l:

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

  1. Mounting partition require first mount point. Create a directory where you want to mount the partition of new hdd:

    sudo mkdir /media/<username>/new_hd
sudo chmod 777 /media/<username>/new_hd

    (Note that the first time you use the sudo command prompts you to enter your password)

    Second step, find the UUID of the partition to mount:

    sudo blkid

    read output, and copy the relevant UUID.

    Finally, edit /etc/fstab (assuming that the filesystem is ext4):

    fields in fstab are:

    <file system> <mount point>   <type>  <options>       <dump>  <pass>

    so add this line:

    UUID=<uuid_new_hd> /media/<username>/new_hd ext4 rw,user,exec 0 2

    To do that, remember to edit with superuser permission, then using sudo:

    sudo gedit /etc/fstab

    Note: Gtk-WARNING when execute this command is normal. instead of gedit you can use nano or vim (non-GUI editor).

    Check if new line was added, by typing:

     cat /etc/fstab

    Then mounting and checking the partitions typing the following command in terminal:

    sudo mount -a

    If everything is ok, this command should not give back any output, and partition the new hd should be mounted.

    Type man fstab for more help and options, or read here as suggested, and type man sudo for help with sudo command.

    The answer was changing the ownership. I moved the directory to /home/micah/Media instead of /media/micah/new_hd. I then entered sudo chown micah:micah /home/micah/Media -R and after a reboot I now have permission to use the hard drive. One question. I know I can use the hard drive listed under devices but is there a way to have the "Media" folder show up on the left side of Nautilus just like "Pictures, Videos"? Thanks for all your help @girardengo
