Swapping 120GB HDD with a 720GB HDD in my MacBook Pro.
By following the iFixit guide I found it relatively simple to replace the HDD in my notebook with a larger capacity HDD. The toolkit I got off iFixit is of good quality and I was able to easily take apart my MacBook Pro notebook.
Research the different specs of replacement HDDs such as acoustics etc. as the one I got is of good quality but considerably noisier than the existing HDD in my notebook.
