Presentation slides.

Learning Objectives
  • Select a disk partitioning style.

  • Work with disk tools.
  • Understand the role of VHDs in Windows 7.
  • Use Device Manager.

Vocabulary

basic disk
A Windows disk designation that calls for the use of primary partitions, extended partitions, and logical drives to organize data.

Diskpart.exe
A command line program that manages disk partitions and volumes, and which includes some capabilities not found in the Disk Management snap-in.

dynamic disk
A Windows disk designation describing an alternative to the basic disk that consists of a single partition occupying the entire disk and containing an unlimited number of volumes in that partition space.

exFAT (extended file allocation table)
A 64-bit version of the file allocation table file system designed for use on large USB flash drives.

FAT (file allocation table)
A 16-bit file system for hard disks that is limited to partitions no larger than 4 gigabytes. 

FAT32
A 32-bit version of the file allocation table file system that supports partitions up to 32 gigabytes in size.

globally unique identifier (GUID)
A 128-bit hexadecimal value that Windows uses to identify a particular operating system component. 

(GUID) globally unique identifier partition table (GPT)
A disk partition style available in Windows Vista and Windows 7 that supports up to 128 partitions per disk and stores critical data in partitions, rather than hidden sectors.

master boot record (MBR)
A disk partition style supported by all versions of Windows that allow up to four primary partitions or three primary partitions and one extended partition.

mirrored volume
A type of hard disk volume that consists of an equal amount of space from two dynamic disks, which contain identical copies of the stored data. If one disk fails, the data remains accessible from the other disk.

native boot
A feature in Windows 7 Enterprise and Ultimate editions that enable the computer to boot from a virtual hard disk (VHD) file, 

NTFS
A 32-bit file system that supports larger volumes than FAT and features such as access permissions, compression, and encryption.

simple volume
A type of hard disk volume that consists of space from a single disk. 

spanned volume
A type of hard disk volume that consists of space from at least two, to a maximum of 32, physical disks, all of which must be dynamic disks. A spanned volume is essentially a method for combining the space from multiple dynamic disks into a single large volume. 

striped volume
A type of hard disk volume that consists of space from at least two, to a maximum of 32, physical disks, all of which must be dynamic disks. The difference between a striped volume and a spanned volume is that in a striped volume, the system writes data one stripe at a time to each successive disk in the volume.

Virtual Hard Disk (VHD)
A file format that contains the entire contents of a hard disk in a single, portable file that administrators can use to move entire virtual machines (VMs) from one host computer to another. In the logical environment of a virtual machine, a VHD functions exactly like a hard disk drive does in a physical machine.
