While I was watching a popout Youtube video in Firefox while moving about 81GB of files from my secondary SSD, which was a backup from when I had Windows 11, to my main drive into the documents folder, my computer suddenly froze up for about 30 seconds until I foolishly turned it off without any response from mouse or keyboard. After I turned it on again, everything was normal and some of the stuff was moved, most of it corrupt though, and I'm unable to mount the secondary SSD anymore, instead only being met with an error saying:
Error mounting /dev/sda1 at /media/(my name)/Storage 1: Unknown Error when mounting /dev/sda1.
