Chapter 8 Supporting Hard Drives

New Technology file system (NTFS)

A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.

Solid State Drive (SSD)

A hard drive that has no moving parts. Also see solid state device (SSD). An electronic device with no moving parts. A storage device that uses memory chips to store data instead of spinning disks (such as those used by magnetic hard drives and CD drives). Examples of solid state devices are jump drives (Also called key drives or thumb drives), flash memory cards, and solid state disks used as hard drives in notebook computers designed for the most rugged uses. Also called solid state disk (SSD) or solid state drive (SSD).

extended partition

A partition type that can exist on a basic disk and have one or more logical drive letters assigned to it. A Windows operating system cannot boot from an extended partition. (10)

logical drives

A portion or all of a hard drive extended partition that is treated by the operating system as though it were a physical drive. Each logical drive is assigned a drive letter, such as drive F, and contains a file system. Compare to volume.

read/write head

A reading and writing device in a floppy or hard drive that is mounted on an articulated arm that moves back and forth over the floppy disk or metal platter. (1)

basic disk

A single hard drive that works independently of other hard drives.

Simple Volume

A type of dynamic volume used on a single hard drive that corresponds to a primary partition on a basic disk.

head

Each side, or surface, of one hard drive platter

Hard Disk Drive (HDD)

The main secondary storage device of a PC. Two technologies are currently used by hard drives: magnetic and solid state.

File System

The overall structure on OS uses to name, store, and organize files on a drive.

active partition

The partition from which a computer boots.

low-level formatting

Track and sector markings are written to a hard drive before it leaves the factory in a process called _____________.

hybrid hard drives

Use solid and magnetic tech. Windows tech is ReadyDrive to support hybride hard drive.

ReadyDrive

Windows Vista technology that supports a hybrid drive is called ____.

cluster

a grouping of a number of similar things

Magnetic hard drive

a hard drive consisting of one or more metal magnetic disks permanently sealed, with an access mechanism and read/write heads, inside its drive

file allocation table (FAT)

the prt of a floppy disk or hard disk where information is stored about the location of each piece of information on the disk (and about the location of unusable areas of the disk), the part of a floppy disk or hard disk where information is stored about the location of each piece of information on the disk (and about the location of unusable areas of the disk)

High-level formatting

you specify the size of the partition and what file system it will use
