Here is my problem: I sold my macbook pro (pre-unibody 2.4ghz - 160gb hd) to someone and I scheduled an appointment for tomorrow (Saturday) morning for the handover. Yesterday night I initiated a fresh install with a secure 35 pass deletion of my HD. The ETA is for tomorrow at 1.00 PM, my appointment is at 8.00 AM and at 9.00 AM I have a plane to catch. So here are my questions: is there a safe way to interrupt the 35 pass erase (it's currently on it's 11th pass)? is it normal that it takes such a long time (48 hours)? I obviously can postpone my appointment but, if possible, I would rather not. Thanks in advance.
