Windows 7 Configuration Chapter 4

Front 1

basic disk

Back 1

A basic disk uses primary partitions, extended partitions, and logical drives to organize data.

Front 2

Diskpart.exe

Back 2

The DiskPart command-line utility contains a superset of the commands that the Disk Management snap-in supports.

Front 3

dynamic disk

Back 3

Dynamic disk can support five type os volumes: simple, spanned, striped, mirrored, and RAID 5.

Front 4

exFAT

Back 4

Also known as FAT64, is a 64-bit FAT implementation that is intended primarily for large USB flash drives. Introduced in Windows Vista SP1, it theoretical limitations are partitions and files up to 64 zetta in size. The recommended maximum size for exFAT partition in Windows 7 is 512 TB.

Front 5

FAT

Back 5

The original 16-bit FAT file system for hard disks, also known as FAT 16, is limited to partitions no larger than 4 GB.

Front 6

FAT32

Back 6

The 32-bit version of FAT can create paritions up to 32 GB in size, with individual files up to 4 GB.

Front 7

GUID

Back 7

Globally unique identifier

Front 8

GPT

Back 8

GUID (globally unique identifier) partition table (GPT)
Supports up to 128 primary partitions
Supports volumes up to 18 exabytes in size
Data critical to platform operation is stored in partitions rather than in hidden sectors
Replication and cyclical redundancy check (CRC) protection of the partition table provide increased reliablity

Front 9

MBR

Back 9

The master boot record (MBR) uses a partition table to point to the locations of the partition on the disk.
Supports up to four primary partitions or three primary partitions and one extended partion, with unlimited logical drives on the extended partition.
Supports volumes up to 2 terabytes in size
Data critical to platform operations is stored in hidden (unpartitioned) sectors.

Front 10

mirrored volume

Back 10

Consists of an equal amount of space from 2 disks, both of which must be dynamic disks. In a mirrored volume, each disk holds an identical copy of the data written to the volume as a fault tolerance measure. If one disk fails, the data remains accessible from the second disk. Because of the data redundancy, a mirrored volume only provides half as much storage space as any of the other volume types.

Front 11

native boot

Back 11

Enables you to create and modify VHDs in Windows 7 and even boot Windows 7 from a VHD, all without having to run a virtual machine manager product such as Virtual PC or a hypervisor-based product such as Hyper-V.

Front 12

NTFS

Back 12

Preferred file system for Windows 7. Its main benefits being improved support for larger hard drives and better security in the form of encryption and permissions that restrict access by unauthorized users.

Front 13

simple volume

Back 13

Consists of space from a single disk. Windows 7 supports simple volumes on both basic and dynamic disks.

Front 14

spanned volume

Back 14

Consists of space from at least 2, to a maximum of 32, physical disks all of which must be dynamic disks. A spanned vlume is essentially a method for combining the space from multiple dynamic disks into a single large volume.Windows 7 writes to the spanned volume by filling all of the space on the first disk, and then filling each of the additional disks in turn. If a single physical disk is in a spanned volume fails, all of the data in the entire volume is lost.

Front 15

striped volume

Back 15

Consists of space from at least 2, to a maximum of 32, physical disks, all of which must be dynamic disks. The system writes data one strip at a time to each successive disk in the volume. Striping provides improved performance because each disk drive in the array has time to seek the location of its next stripe while the other drives are writing. Striped volumes do not provide fault tolerance and you cannot extend them after creation. If a single physical disk in the striped volume fails, all of the data in the entire volume is lost.

Front 16

VHD

Back 16

Virtual Hard Disk
A VHD file 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. VHD format support Virtual PC, Virtual Server and Hyper-V products.
