They have a number of spare locations they can swap into use when a bad patch develops. This is invisible except to something like smart reporting. Rule of thumb - when a modern drive starts showing bad sectors to the outside world, its already well past its use by date. So something like SMART is the only way for the average Joe to get the health of a drive. Google has lots on this sort of thing BillK
