Hi there, this is somewhat of a strange enquiry and I'm aware it may make me look like a fool. Once upon a time I purchased a Maxtor external HDD (as so: http://www.play.com/PC/PCs/4-/87055...-Hard-Drive/Product.html?ptsl=1&ob=Price&fb=0) Long story short, it broke and is now in a shoddy external casing. I'm interested in using it as my MBP's main HDD, and have read up/ensured I have the correct tools... But before I go tearing my laptop apart, will the HDD even fit/be compatible? I know very little about HDD's, and only wonder if I've gone completely off-track with this idea. Really appreciate any help with this.
