    I bought a new WD portable HD and when I plug it into my MacBook Air it won't allow me to put anything on it. My friend mentioned I need to go to Disk Utility and format it properly. Does anyone know the correct steps so it works every time?

    I have Disk Utility up but what do I click from there? I clicked on the HD but do I partition or what?

    Depends whether you want a partition, or not. There's no real need to, but it's a personal choice.

    You have to have at least one partition on a disk to make it usable. Click on the Partition tab in Disk Utility. Near the bottom you should see a button labeled Options. Click that and choose GUID.
    Save that setting and Type in a name for the new disk. Choose Mac OS Extended (Journaled) as the Format and click Apply (Warning: This will erase any data on the drive.)

    If you want more than one Partition on the drive, (each partition will appear as a separate drive to the OS) change the volume scheme to your desired setup.

    I have a Seagate that has 2 partitions, one is NTFS and the other is GUID; works great.
