Sooooo......why make an article for MBA users without an optical drive, when the bulk of the middle of the article mentions Cloning the Install DVD....

There's no optical drive on the MBA!!!! And MBA did not come with any install DVD either.

Very confused! I need to sell my MBA, so I want to restore to factory settings, and I was sure this article, based on the beginning text.

Is there a way create a reinstallation partition on an external hard drive from disk utility WITHOUT a DVD or optical drive???
