So, i am thinking of sending my macbook in to get the discolouration issue fixed, and i dont want to loose my HDD data. What is the proper way to go about backing up all my data so if it does get erased, i can just click around a couple times and its back the way it was! I have an External thats FAT32 formated, can i just connect it, and drag over my HDD and then to restore it drag it all back ? or what? Thanks for the help!
