In /dev/sda1 is a NTFS Sony Windows Recovery file-system. It is set to auto-mount via /etc/fstab to /media/
I was copying an NTFS partition image using dd from an external USB hard-drive to /dev/sda2 (after replacing the laptop's internal hard-disk).
I'm not sure when it began but I noticed the CPU monitor shoot up to 100% and it has remained there for more than 10 minutes. The CPUs are in I/O wait and I noticed in the process list mount.ntfs has been hanging around.
Despite the I/O wait there is little to no hard-disk activity judging by the LED indicator.
I tried to kill the process using "sudo killall mount.ntfs" but after entering the password the terminal froze before carrying out the command. I tried using sudo with another command from another terminal shell and that has also froze after the password was provided.
ps -eFlL | grep mount.ntfs

I tried switching to VT1. It accepted my user password to log-in and displayed the motd but then froze before any shell prompt can be displayed.
It's not clear what you copied from where to where and how.
Anyway it looks to be a hardware problem. Check your RAM and disks for bad sectors, e.g. by the utility badblocks.
