External SSD (with Manjaro installed) failed to unmount before shutdown/restart

Hello guys,
I got a error message when i restart/shutdown my PC, that my SDD (Samsung Portable SSD T5)
are busy and won’t unmount for shutdown. I have a screenshot with the error message:

I have this error after the third reboot since i first time installed manjaro on my External SSD,
after 2-3minutes blackscreen this message showed up… now this error comes everytime but without any delay.

If you guys need any logs please let me know, but please explain me how to create this, because im still not into this linux stuff.

I hope you guys can help me out, thanks in advanced.

EDIT: Okay, here are my logs:

Partition table entries are not in disk order.

There are many ways to install, so start by explaining in details how you installed it and what medium you used, it might be related or not…

Installed the (non-Minimal ISO) per USB Livestick (MBR) normal way (no Architect) but with manual partition
200MB EXT3 (Boot)
88GB EXT4 (Root)
332GB EXT4 (Home)
3GB (Swap)

Just as i said, the first 3 times i could restart Manjaro without a problem… I remember i just deactivated some services but nothing seriously, the closest was Removeable Device Automounter.

But as far i rember, that was after i had this error already.

Seeing you mentioned that you used MBR more info on your hardware could also help others to help you better:

At first sight one would think what does hardware have to do with an error about failed un-mounting, but you never know.
Providing more info as what is needed can only help others to help you more :wink:

I just noticed from your Screenshots, that those were taken from within M$ :thinking:
Are you using a VM to boot your Manjaro?

Please correct if i placed info out-of-line, i just replaced the | with a newline…

Skylake i7-6700K@4700 MHz
16GB DDR4 G.Skill 2800MHz
MSI 2080Ti Ventus OC
SDD Samsung 830(256 GB)
NVMe Samsung 960 Evo(512GB)
Creative Soundblaster AE-5
Dell S2417DG(1440p 144Hz)
Rift CV1

Nope, its inside Linux Manjaro, no VM at all… only some layout tweaks, that it looks closer to Win7 :slight_smile:

You still see the difference in the taskbar where the manjaro settings manager is shown up.

I have no other HDD’s or SSD’s activated with Linux. Any more info required?

And my Samsung T5 External USB Device is pretty new and its still doing a stable job with my first manjaro install since 3 month, i had only 1 blackscreen, but that was related to Shotcut i think.

My 200MB Bootpartition is already used with 150MB. Could this cause maybe a problem.

It would have helped more if you used the output of the commands in the link i gave, which include vendor:device ID’s etc…

A complete list of all your storage devices would have been better, eg: sudo fdisk -x

But anyhow hope it will be enough for those that will help :wink:

Added the Logs to the first Post.

Looks like this bug is not rare, but still no fix… that’s really sad :frowning:
