In /dev/sda1 is a NTFS Sony Windows Recovery file-system. It is set to
auto-mount via /etc/fstab to /media/WindowsRecovery.
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.
