  • Save this to a file somewhere, let's call it sda-debug.sh
  • Make the script executable: chmod +x sda-debug.sh
  • Run it as root: sudo ./sda-debug.sh
  • Paste the content of /tmp/sda-debug.log here

EDIT: changed the script to log everything to a file for easier copy-past-ability.

This script will unmount the problematic drive and try to mount it to another place /tmp/myprecious, a temporary place. Then, as it says, will attempt to read and then write to the drive. Finally, it removes the file it wrote to test writeability, unmounts the drive again and removes the temporary mount place. The scripts needs root access to mount and unmount and possibly to write and read.

Please don't run a script you found on the internet with root access without knowing what it does.

I would remove the formatting of the script. For me that would never run as a bash script as it's filled with markup. Not sure if it shows up nicely for you or not so figured I'd let.you know it may not be displaying for others at least.

Ampersand was escaped in web UI, editted to reflect that. Everything else is displayed fine.

Considering the first line is a span block, I don't think you realize what you see is not necessarily what others see.

I now understand the issue better, but since it's a request from a lemmy user and the issue appears to be on kbin - I'll leave it as is.

Makes sense. Though I'll note I find folks find help via methods of others asking for the same thing so a Kbin user could easily come across this post trying to find an answer to a similar problem. That being said, I don't have a good suggestion for a workaround so leads me back to "makes sense."

Also, if you're dual booting, Disable Fast Start in Windows! That'll prevent drives from being mounted on Linux since Windows never technically "shutsdown" when Fast Boot is enabled.
