Managing Disks
Disk Management is a system utility that lets you inspect and manage hard disks. You can use it to initialize a disk; create partitions; and format partitions with FAT, FAT32, or NTFS file systems on
new hardware. Otherwise, use Disk Management to assess a disk's health, assign drive letters, format, and perform related tasks.
To open Disk Management:
1. Choose Start > Control Panel > Performance and Maintenance > Administrative Tools > Computer Management; then click Disk Management in the left pane (Figure 19.23 ).
Figure 19.23. Drive Management is a cog in the larger machine named Computer Management, which groups many tools described elsewhere in this book. Click a tool in the left pane's console tree to open it.

A
partition, or

Every hard disk has one partition, but you can create several on one disk, mainly to:

Unfortunately, Disk Management is lazy and
erases a hard disk before partitioning it, which makes it suitablein real termsfor blank or new disks only. If you want to create or resize partitions without erasing everything, buy PartitionMagic ($70 U.S.; www.powerquest.com/partitionmagic).
