New Ubuntu user here... I have Ubuntu on my 250GB SSD and I have another 500GB on my laptop that Ubuntu can't find. I'm not sure where or how to start finding it.
You might need to edit your /etc/fstab to mount your extra drive. Here's how you can check.
lsblk into a terminal like Organic Marble suggested. Devices named like
sdc are going to be distinct drives, while
sda2, etc are partitions of that drive.
If your drive isn't showing up in
lsblk, then someone more experienced than I will need to answer your question. I'd guess it means that your drive isn't connected properly, but I don't know for sure.
However, if you do see a drive that's showing up in
lsblk, but doesn't have a MOUNTPOINT, then we can likely assume that it's your drive, and we can follow a few simple steps to get it set up. Let's assume that your device is
First, figure out which partition of your 500gb drive you want to mount. If you have multiple partitions, then you'll need to do this for each partition. Let's assume you want
Next, you need to figure out where you want to mount the partition to. I usually end up mounting all of my drives in the
/media directory, with a subdirectory for the partition. for example, my local network share is mounted in
/media/fileshare. Either way, decide where you want to mount this partition, and create a folder for it, like this:
sudo mkdir -p /path/to/mount/directory.
Next you need to figure out the filesystem type. Type
sudo parted -l to get a list of all drives connected to the computer. Find the drive in the list that matches your drive. The partitions will be listed starting at 1; note the column for 'file system'. Let's assume yours is
Now, open your
/etc/fstab file with root permissions using your favorite text editor. Nano is pretty easy to use:
sudo nano /etc/fstab. The
fstab file contains information about all the drives that get mounted to your computer and tells the OS how and where to mount them. You should see a couple lines in there which correlate to your main drive as well as your swap space. You want to add a new line sort of like this one, but with whatever the values you came up with are:
# partition mount location filesystem options dump pass /dev/sdb1 /media/fileshare ext4 defaults, 0 2
defaults refers to all of the default options found here. I'm no expert on
fstab options, but someone else might be able to help you more here.
Now, save and quit whatever text editor you used, and run the command
sudo mount -a; this re-mounts all partitions found in
fstab. Assuming you did everything right, your partition should be mounted, and you should be able to access your files from whatever mount point you specified in the
