Partitions as their name suggests are only a way of dividing a hard drive into discrete segments for different uses. Any physical problems can affect all partitions since they're not really separate.
As for partitioning, I always use Parted Magic, a live CD which does everything from creating and deleting partitions to resizing and reformatting them.
