Partitioning, Partition Sizes and Drive Lettering
Partitioning the hard disk is the act of dividing it into pieces; into logical volumes.
This is one of the first things done when setting up a new hard disk, because partitions
are one of the major disk structures that define how the disk is
laid out. In fact, you must partition the hard disk, even if only "partitioning"
it into a single partition, before you can format and use the disk.
The choice of how the disk is partitioned is important because partition size has an
important impact on both performance and on how efficiently the disk's space is utilized.
Even though in many cases you can fit an entire disk into one partition, it is rare that
you will actually want to do this, for performance reasons. This section explains the
reasons why, and also examines the commonly asked question: should I use FAT32?
