Ok so I bought a macbook the other day and decided to upgrade the hard drive for more space and so I bought a bigger hard drive but the catch is that the new hard drive has pre-installed software on it. My question is that do you have to format the new hard drive and if you do how would i go about copying the applications off of it to a external hard drive then formatting it then putting the applications back on it? Sorry if this doesnt make a lot of sense...if you have any more questions that would help you to answer my question then by all means ask away. Thanks in advance and sorry for the long post!!
