I'm using Ubuntu Server 22.04. The disk shows blk_update_request and spams it into console after I shut it down remotely and it worked perfectly fine before, but now it shows this error. I suppose it can be disk, that is broken, because I booted it back up a few seconds later after turning it off. It also started moving its head once in a second instead of being silent (probably because it pings for a sector which has an error)
Strangely I don't have a chance to work with it via keyboard since it is blocked with this message. I can still connect to it via ssh, but my nextcloud server is not working anymore. I can work with it via ssh freely, so can I backup all of my data or should I somehow restore the sector without losing all the data?
I also noticed that other system messages appear in my console after startup

sudo smartctl(usually also accessible from your partition manager). You might want to also check for drive overheating. – pbhj Sep 19 '23 at 18:41
