Hey there! I have just installed my first Linux distro on a Raspberry pi 4 (Ubuntu Mate 20.4).

I am in the processing of trying to move over from the SD to an SSD.

After plugging the SSD into the Pi, nothing appears, and I cannot find it in the file viewer.

Is it supposed to be like that, or is something wrong? What can I do to find my SSD?

(Also a side question if anyone knows: I cannot seem to find a way to install Raspberry Pi imager onto the Raspberry itself with this distro (Ubuntu Mate 20.4 arm64--help?))

Thanks!

Show us the output of please.

Are you sure about this command? With me it reads invalid option. Thanks!

You shouldn't type a command involving "sudo" or "su" without first checking "man command" to see what it will do.

If you had ran "man fdisk", you would discover that "-l" is short for "--list"; you've presumably misread it as the number one.

Some commands have both a -l and a -1 option, so it's important to check which one you need before entering a command.

Right on! Thank you.
So that gave indeed some different results:
It found the SSD, listing it at the bottom

EDIT: I'm accessing the forum from another computer (hence the picture).

I would expect both partitions to be mounted automatically and the Pi 4 should be capable of handling the current load.

Post the output of the command:
lsblk -f

I have not played with Ubuntu on a Pi yet and do not know how the desktop is configured but its possible the drive is not automatically mounting because the UUIDs match your SD card. You might have to manually mount them.

Didn't do nothing when I typed to code unfortunately. Appreciate it tho!

They probably will not show up as anything in the file browser. You will need to navigate over by clicking on other locations in the file browser and select computer. Then scroll down to /mnt ...
Or just use the terminal and

cd /mnt/sda2

In the /mnt directory I found additional folders with following names:
bin, boot, dev, etc, home, lib, media, mnt , opt, proc, root, run, sbin, snap, srv, sys, tmp, usr, var
(should be worth mentioning that the mnt folder from the list listed was empty).

The command in terminal said "No such file or directory"

I assume that is because /dev/sda2 is mounted to /mnt and not /mnt/sda2. Looking at the output of the lsblk command should show the current mount points.

As assumed /dev/sda2 is mounted to /mnt and not /mnt/sda2
sudo umount /mnt
sudo mount -t ext4 /dev/sda2 /mnt/sda2

sudo unmount /mnt
[sudo] password:
sudo: unmount: command not found
desktop:~$ sudo mount -t ext4/dev/sda2 /mnt/sda2
mount: mnt/sda2: can't find in /etc/fstab.
