Managing Disks and Drives 19
The disks and drives configured within or attached to your computer provide stor-

and external storage devices in different ways. You use internal storage devices for
the operating system and your primary storage. You use external storage devices for
you secondary storage only.
Disks and drives are one area of computer configuration that you won’t work with
often. Primarily, this is because disks and drives are something you need to prepare

rather than configuration tasks. Preparing a disk for use involves three main tasks:
Partitioning the disk with volumes
Formatting the disk volume
Mounting the disk volume
You can partition a disk into one or more volumes. You then format the volumes
with the File Allocation Table (FAT) or FAT32 filesystem, or with the NT File Sys-
tem (NTFS), as appropriate. Finally, you mount the volume to a drive letter or file
path. When you format volumes with NTFS, you can use compression to reduce the
disk space used, or encryption to add an extra layer of protection to your data.
Configuring Disks and Drives
Like filesystems, disks have a particular formatting that determines how you can use
the disk. Windows Vista allows you to configure disks to be either the basic disk type
or the dynamic disk type. Basic disks are the traditional disk type Windows has used
since it was first introduced. Dynamic disks are a newer disk type that was intro-

disks. Consider the following:
