I'm going to put a new hard drive in my iMac, removing the old hard drive. Should I de-authorize my current computer first, or will iTunes recognize that it is the same computer? In other words, does iTunes authorize the computer, or the hard drive?
I was actually looking for a more solid answer, such as, "iTunes gets the machine specific ID number and uses that" or, "Authorization is stored on the local machine's hard drive and removal will cause you to lose an authorization.
The answers make sense, but "inquiring minds want to know".
