Also for this command, the moment after it has been plugged in:
sudo dmesg -T | tail -n 50
I tried
- 2 usb ports on the laptop itself
- 1 usb C port on the laptop itself
- 1 usb port on my docking station
I checked lsblk every time, I don’t see any difference.
The last log is like this.

Well, now you’ve made me say it. 
I’ve never used diff before, so not really no.
I’m pretty sure the problem is your USB port. The device is not properly detected. Some Samsung devices are known to not be 100% compatible with the specs. You could try kernels before 5.10.

That was my guess as well…was just trying to confirm it before saying anything.
No problem 
I find it also hard to read. Below image should be (more) clear. Right?
Rightclick to open bigger in new tab.
My best guess is the same as @Wollie’s. It might be a defective SSD or, more likely, something’s wrong with the power’s supply. Hey, it might even be the cable!

I tried different physical ports. Also, I had never had issues before with my ports. I am guessing it is more probable that the device is not compatible. But how would I know that for sure?
I tried two different cables.
Is there some sort of encrytion active on the disk? https://askubuntu.com/questions/1341088/how-access-files-on-portable-ssd-samsung-t5-on-ubuntu-20-04
If there was, it would still have been listed with
sudo lsblk
Test it i another PC, and see if it works there…
Jup, I was on my way to test it on a Windows machine. I just tried, and it works, plug and play. It has some sort of tool where you can specify a password. I did not activate it. So I guess it is not encrypted now. Retested it on Manjaro after it with no difference as far as I can see.
I also found this source, but it is just one source which says it is not compatible with Linux? https://askubuntu.com/questions/1204208/samsung-ssd-t5-compatibily-with-ubuntu
Try
$ lsusb -v
I vaguely remember one thread where the t5 ssd showed up after using that command…
edit: found it
But that should be fixed now according to the newest post in that thread

Yeah, I also came across that theard. I tried the command. The device is listed. What do I do after it? I don’t see any difference.
How do I know If I have the fix on my system? I did an upgrade of my system since a long time yesterday. Now I want to back up everything. I think I am also on an older kernel, 4.14.257-1.
This could be a factor, try to rule it out. Trying newer/current kernels is easy on manjaro:
https://wiki.manjaro.org/index.php/Manjaro_Kernels
Try to list partitions and/or mount them:
$ fdisk -l
$ lsblk -f
On the Arch site about this problem was posted:
The patch was merged on kernel version:
4.4.293
4.9.291
4.14.256
4.19.218
5.4.160
5.10.80
5.14.19
5.15.3
All available kernels in Manjaro are above and should have the fix.
