Couple of things happening here. You want to mount the drive
/dev/sda3 to access the files in
df -h is reporting that
/dev/sda3 is already mounted at
/media/snow/Envision, but you tried anyway with the command
sudo mount /dev/sda3.
The correct format for
mount is (you missed the
sudo mount /dev/<drive> /<mountpoint>
sudo in front is only a requirement unless you are currently the
sudo mount /dev/sda3 spat out that particular error message is because (at a guess) you did not include any details about
mount will look in if the mount point is missing.
BTW, even if the drive is mounted at one point, you can re-mount at another point (so that one drive is mounted in two locations) but personally I do not recommend this.
If this drive is to be mounted only a few times (like an external drive) then you can do this:
sudo mkdir /Envision
sudo mount /dev/sda3 /Envision
You can then access the drive contents at
/Envision. For example:
ls -al /Envision
Alternatively if you are keeping this drive in your system all the time you can edit
/etc/fstab and then the drive will be found when you reboot the system (or if you do
sudo mount -a). To add the drive to
First get the UUID or universally unique identifier like so:
The output will be something like:
/dev/sda2: UUID="85ec7b1a-7d67-47f1-bcc9-4c4f4ed370b5" TYPE="ext4"
The important part is the
UUID="85ec7b1a-7d67-47f1-bcc9-4c4f4ed370b5" BUT you also need to make sure you get the
/etc/fstab in a text editor as
root. I use
vim, so I do:
sudo vim /etc/fstab
Now add a line with the drive details. Using my example above:
UUID=85ec7b1a-7d67-47f1-bcc9-4c4f4ed370b5 /Envision ext4 nosuid,nodev,nofail 0 0
If the drive type is
ntfs you would replace
nfs BUT I'm not 100% sure what the other options would be. You would need to check them.
Save the file and type
sudo mount -a and if there are no issues your drive will be mounted and will be mounted on the next reboot as well.
