Setting Up Your Portable Drive

Setting Up Your Portable Drive

The first obstacle to deal with is the fact that your drive/chip/whatever you’re using
probably didn’t come formatted with Macs in mind. Your Mac prefers a Mac OS Extended Journaled format.

So fire up Disk Utility (Applications→Utilities→Disk Utility),
select the device in the lefthand column , and then click Erase and let Disk
Utility do the hard work. When it’s done, you’ll have a blank drive ready to hold your
Home folder.
