Well, I was using my machine as usual, downloading some stuff in Nicotine while all of a sudden it starts throwing me permission error for the files I was downloading, it was weird so I went to my downloads folder and noticed that the folder where it was being downloaded on was protected, I tried to change it using right click, properties, and after I presses F5 all my system appeared as read only. I noticed that another folder also got read only while I was downloading it from Nicotine yesterday, I don’t know if it is related.
I’m using Ubuntu 18.04.4 LTS.

I believe btrfs is more sensitive to disk damage than say ext4. That would be safer to use as it makes the drive read-only before ext4 would, giving you more time to prepare for a backup/restore. What filesystem are you using? Give us you dmesg regarding the FS type, that should be a good start.
Filesystem corruption maybe? How old is the hard drive?
Do you see any warnings or errors on boot? If you run the command “sudo dmesg | less”, do you see any errors or warnings in the log?
A bunch of questions, but it’s a start!
Don’t SSDs sometimes become read only when the filesystem is corrupted or the SSD is old? The second one might be a myth, I was never sure.
This is interesting… The write limit is gone, so the drive to self preserve allows only reads… It sounds logical… Anyone got any solid idea/knoweledge on the topic?
As far as I know that’s correct. Flash memory has a certain lifetime in writes. But it’s usually an extremely large number, especially for SSDs.
Swap space on an SSD can reduce it’s lifespan since it’ll be written to more often, but I don’t know how much of a reduction you’d get.
