Hard drives can fail within a year if they are faulty. I had this kind of 
experience with a Western Digital Caviar Green drive a few years back 
(separate from the pathological head parking behaviour that wasn't advertised 
by the manufacturer because the Windows driver code was dealing with it, but 
where everyone else was on their own). Fortunately, the failure was relatively 
graceful.

Try smartctl to see what the drive controller thinks:

sudo smartctl --all /dev/sda

Here, /dev/sda is the SATA device of interest. Use lsblk to see details of 
devices.

Certainly, Chris is right in that hard disk failure can cause all sorts of bad 
blocking behaviour, although I'm not sure whether it would leave processes 
running at 100% CPU.
