It's really hard to say whether the entire disk or just a portion of
the disk might be unreadable. I would say, that where Ubuntu resides on
the disk at the moment, is where part of the drive is now unreadable.
One way to tell is if Windows locks up from time to time, then parts of
the disk where Windows resides are also damaged.  For me that indicates
that the drive is on the way out. If Windows is fine, then you _might_ be in luck with a fresh install.

My response was purely from experience with having a similar problem a
few times over the years. The disk would just disappear then
reappear a number of times in the OS and would take ~5-15 seconds to be mounted by the kernel again (root partition was not on these disks). I could see this by doing a tail -f /var/log/syslog or journalctl -f, for systemd nowadays, and you would see the same "I/O error, dev sda, <sector number> like the ones in your screenshot. A few weeks later, they stopped working or were to unreliable to put data on.

Best of luck! Let us know how it goes so we can help further if need
be.
