Please explain how this is done. I don't believe you are correct.

I probably will need to add new music to the drive from time to time. My username is nick so how about mounting to say /nick/Music/music

And then in terminal mkdir /nick/Music/music to create the mount point.

And then changing the fstab file last entry to:

# /dev/sdb1
UUID=3b754aac-49bb-46fd-b3fc-e253449a1f62 /nick/Music/music ext4 0 0

hm. That is quite simple. When you open any tool like gparted you can format the whole drive as <filesystem>, and also you can use mkfs both on device and partition. And also windows can do that (but I'm not really sure, probably now it creates a partition table anyway).
You can try it with a HDD/SSD or usb stick or an SD card. Whatever you wish.

I posted you the right order. Do not mix the steps.
First make the dir, then edit fstab, mount it and finally you can use it.
Do not use that dir without mounting the filesystem.

Thanks, I'll do that as soon as I finish my lunch.

I'm not sure what you mean by that bit.

do not put/create any file/dir into that dir or in a subdir under the mount point if the filesystem is not mounted.

How do I mount the filesystem?

it was already discussed: use the mount command. Also see the link I posted, everything is explained very well.

pan 64 is right. Creating a directory does not mount a file system. A file system must be mounted to be usable. The only file systems that are mounted are those automatically mounted by entries in /etc/fstab and those that are manually mounted by specific mount commands. When you boot a system there is a default file system on a default drive that is mounted according to an entry, usually the first, in fstab. Others may also be mounted according to entries in fstab. Those are the only file systems immediately usable. To get to the information on a drive it must be mounted somewhere, i.e. the system must be told about it. Look at it this way: you can't get water out of a hose unless you attach it to a faucet or some other source of water. The mount point is a directory. Therefore, the directory must exist before you can mount the drive or partition. Not vice versa. And by the way, you don't mount a drive, you mount a partition containing a file system. One drive can contain one, two or many partitions (filesystems),

Still no go.

When I used mount -a I didn't get any error messages. But there is no sign of the music files in nick/Music/music

With respect, it may be well explained to those who are familiar with the Linux OS, but to anybody else is looks like a mass of contradictory instructions.

I thought that I was mounting a second hard drive. All of a sudden we are talking about mounting a file system.

Post the current contents of /etc/fstab. Copy and paste it, use 'Wrap Quotes' button at the top of the editing screen.

Also run the command lsblk -f and use the Wrap Quotes. This keeps the information formatted for us to see it.

In your case, the second drive has one file system. You mount file systems, not drives. SDB is the drive, SDB1 is the first partition and file system on the drive.

I have created the directory nick/Music/music, and I have put an instruction in fstab to mount SDB1. And then I have issued the command mount -a. So what else is necessary?
