Hi all, I first noticed my hard drive 'clicking' about a year/ 6months ago(?), recently it has been clicking a lot more, maybe once every 5mins? Sometimes multiple clicks in a row! Is my HDD about to fail?? The laptop is fairly old now and I've had it throughout my teenage years so its taken a beating; it's horrendously slow, getting the beach ball every 5mins (literally), and sounds like its about to take off (cleaning the fans no longer helps). Despite this, the laptop still does its job and I'm a student so money is tight. I'll buy a new mac in a year or so. I presume now is the time to replace the HDD with an SSD, and I'm hoping this will in turn make my laptop run slightly smoother as well??

Was slightly worrying.
