How to replace a hard drive on a laptop (sata)

A while back my flat-mate’s laptop hard drive keeled over and died. It wouldn’t boot and wouldn’t read in a caddy, and as there was no back of the data, it was all lost too. Only one thing for it then, buy and install a brand new hard disk.
In this tutorial, I will show you how to physically replace the hard disk, I won’t be showing you how to install windows now and there are many other blogs that cover that.
Hopefully this will give you the confidence to go ahead and replace a disk is you need to.
