Hey everyone. I'm transferring my entire hard drive to an external (just the files, I don't want a bootable drive), and I noticed there are only about 177 gigs being transferred, while my hard drive has about 182. Thus, there are 5 gb unaccounted for. Any idea why this is happening? I just don't want to leave any important stuff on here before I clear the drive. Thanks. To transfer the files, I was simply using command + a on all the files in Macintosh HD and then dragging and dropping the files into a folder on the external drive.
