Get a drive out of the read only mode
I got a problem with my new m2 ssd KINGSTON SA2000M8250G.
I just installed it 2 weeks ago. Now out of nothing it stopped booting with the following output.
Failed to flush random seed file: 5712F72E
Error loading \EFI\Pop_OS-c6e0a2ef-5953-402b-ad6d-2a95da3956d7\vmlinuz.efi: Not Found.
So i tried around checked my BIOS if secure boot was enabled just to make sure and it wasn't ...
So i got a Ubuntu Live USB and played around and mybe i messed it up even more... (I am not sure)
So now my drive is in Read only Mode And i really need some help :). The Drive does not contain important data! So losing data would be fine if it is usable again.
Some Info:
- The dirve is an Internal one.
- The dirve contains a system
I used smartctl to get some information about the drive.
sudo smartctl -x -q noserial /dev/nvme0
The output:
smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.4.0-42-generic] (local build)

I tried the following. To get file system and mount point information.
lsblk -f | grep -v loop

But there was no output from the commands above.
How to get it out of the Read only Mode xD
Thx for helping me out.
Solution 1:
This here
Media and Data Integrity Errors: 17,200,105
means it's really really broken. Which is why it put itself into read-only mode.
Get it replaced.
Solution 2:
Although your smartctl looks different than the ones from my SSDs your smartmontools log information tells you all:

This happened independant of what you did on higher levels with the drive, for instance on file system level. There is a certain probability though of your behaviour causing this erroneous behaviour: The drive reports unsafe shutdowns.
Please monitor this attribute when using your next drive. Avoid irregular hard shut downs.
As for the comments, I totally agree with what Kamil M. said.
