Tak

As I left the machine now and will have access to it next week, but I will keep you updated, I upvoted your answer though :)

@Benjiover_9000'benchonaut'I will check that in the next couple of days and let you know how it goes, and mark it as solved thank you so much

also you are pretty sure it's not an OS issue, right?

but I can try restic

Okay, I used to use Clonezilla or macrium reflect, but they are kinda slow

okay, I will

an image of this disk only or the system disk as well?

HAHAHA OKAY

Also you are pretty sure it's not an OS issue, right?

What do you mean by "another controller"?

Okay, shall I try these mounting options on this disk before buying a new one? or you are pretty sure this disk is faulty?

So no need to partition it?

Yes

And could you advise me with what the mount command to put on fstab?

@Benjiover_9000'benchonaut' You can ping me when you post something :)

I will send the supplier and ask them to send a new drive since this is not new, right?

@Benjiover_9000'benchonaut' New to linux though, so I appreciate your help, you are always welcome to let me know if anything related to blender and I can see if I can help :)

Thanks man, I used to use blender a lot, and I love it :)

I can buy skyhawk/ironwolf/exos any of them is better than the other?

@Benjiover_9000'benchonaut' You can ping me with my username here when you add anything to the chat so I can get notified and check it.

I see so many models

any recommendations on which model I should get?

And I will probably buy a new 8TB seagate disk

Okay

I think I have an external disk reader which is connected using USB

according to the supplier they checked the harddrive on another machine and it's working fine.I really don't know what they did or even if they did anything actually.

I am not sure, I can check

And it seems that the supplier didn't replace the drive 1 month ago, right?

so this means you are pretty sure it's a disk hardware related problem, right?

oh okay

Yes, the data is important

disk*

So would you suggest me buying a new 8TB seagate drive and copy the data over to it?

Oh okay, this is strange as I sent it the machine to the supplier who said they replaced the disk but I feel they didn't

Is that disk old? I see it has been powered on for more than 2 years?

so what would you suggest me to do?

Oh okay

It is English

Shall I press "Start Self-test"? when I press on it gives 3 options Short, Extended or Conveyance

Here I choose the 8TB on the gnome-disks

First, Thanks for trying to help me, I really appreciate it

I ran gnome-disks and here is the result dropbox.com/s/cjpo7c0ukaqbd3l/gnome-disks.png?dl=0. do you think it is a hardware issue with the disk or something from the OS?

No it’s not a virtual box, and not a USB disk. Did you get the chance to check the link having the outputs of the commands you asked me?

Thanks for your reply. I've updated my question where if I even tried remounting the drive with an admin user it fails as shown in the question. I've run dmesg journalctl and S.M.A.R.T and placed the results in this link dropbox.com/sh/bgw1rkbhj1vqrn0/AABGVaqh-LMoc8oAyVwqLwyIa?dl=‌​0 I'd appreciate it if you could check it out?

would you like me to make a new specific question so you can place this answer? as I feel it's so detailed and will be very useful for many people
