Anyways new Mac user here But I was installing iWork, and had the Pro on my lap, and Went to put it on a table. As soon as I moved it the slightest bit, I heard this horrible grinding, and thought I ruined the disk. Luckily, it still works (with a circular gash), but is the OD supposed to be like that? Thanks!
