Hi All, I have a Early 2012 17" MBP & will soon be upgrading the existing factory supplied Hard Drive for something much bigger - it is a few years old now & probably might give out in the future so I thought why not just get a newer & bigger one as I need the extra space anyway. I would like to ask, if I wish to partition the new drive into two equal parts of say 1TB each, how should they be named? Should it be: Partition 1: Macintosh HD Partition 2: Mackintosh HD 2 or Macintosh HD B or something else? The reason I am asking about this, is I am thinking about using one partition as per normal for my stuff & the other for keeping certain client & business confidential data/info which I can then password protect or encrypt etc. If I ever get hacked or the lose the laptop/data, at least I have some assurance to clients that their data was encrypted or password protected etc. Is this a good idea or is there a better way? If I do not partition immediately, can it be done at a later date without losing any information/data on the single Mackintosh HD & be able to transfer data to any newly created partition? Many Thanks!
