There's a secure wipe option. You can crank it up to some absurdly paranoid set of passes, although it takes a day or two to complete at that level given a reasonably large drive.

There is no physical reason to use more than one pass on an HD. And of course erasing an SSD is near-instant.

My understanding runs counter to your assertion. Why do you say that there's no physical reason to use more than one pass?

Student discounts generally require that it be for personal use. Edit: Added after the jrockway and tylerhowath replied, but didn't want to reply to both: From the Apple Sales and Refund Policy… Purchases from the Apple Store for Education Individuals are not for institutional purchase or resale. I presume the same applies to the in store discount. Apple has enough lawyers to cross that "t".

Putting "From the Apple Sales and Refund Policy… Purchases from the Apple Store for Education Individuals are not for institutional purchase or resale" in a refund policy or anywhere does not mean Apple has the right to restrict resales.

It doesn't say Apple can prevent the resale, it says the buyer is not entitled to the educational pricing if they are buying the machine for the purpose of resale. The fraud is for the student to buy a machine under the pretext of using it himself, knowing full well that he is buying it for resale.

I'm sure it's either in, or incorporated by reference, that text that people don't read about accepting conditions of a sale.

In practice, Apple can't afford to sue every weasely kid who thinks he's entitled to free money for being clever. So they also restrict it to one computer a year and take their losses on the young criminal masterminds.

There is no way to detect HD contents past the current write. It has never been demonstrated that anyone has done it, and data recovery companies will not recover your disk if you accidentally erase the blocks. The misconception that you can do that comes from a misreading of a paper by Gutmann that only applied to an obsolete disk recording method in the first place.

The reason people use methods other than 1-pass erasing is because of marketing thinking that more passes looks better on the product features. Or because the IT people enjoy buying heavy machinery so they can destroy stuff with it.
