STUDY
PLAY
When using an 80-conductor cable-select cable, the drive nearest the motherboard is the _____.
Master
_____ on a circuit board inside the drive housing is responsible for writing and reading data to these tracks and sectors and for keeping track of where everything is stored on the drive.
Firmware
The top and bottom of each disk of a magnetic hard drive have a(n) _____ that moves across the disk surface as all the disks rotate on a spindle.
Read/write Head
A _____ drive has one, two, or more platters, or disks, that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard.
Magnetic Hard
The ATA interface standards are developed by Technical Committee T13 and published by _____.
ANSI
During the _____ formatting process, you specify the size of the partition and what file system it will use.
High-level
Each side, or surface, of one hard drive platter is called a _____.
Head
_____ transfers data directly from the drive to memory without involving the CPU.
DMA
A technology that configures two or more hard drives to wrok together as an array of drives is called _____.
RAID
______ mode involves the CPU and is slower than DMA mode.
PIO
Windows Vista technology that supports a hybrid drive is called ______.
ReadyDrive
External _____ is up to six times faster than USB or FireWire.
SATA
The ___-conductor IDE cable has half the number of pins as it has wires.
80
The total number of _____ on the drive detemines the drive capacity.
Sectors
The first sector on the disk, called the boot sector or ____ record, contains the information about how the disk is organized and the file system used.
Boot
If you are mounting a hard drive into a bay that is too large, a _____ kit can help you securely fit the drive into the bay.
Universal Bay
_____ is a system BIOS feature that monitors hard drive performance, disk spin up time, temperature, distance between the head and the disk, and other mechanical activities of the drive in order to predict when the drive is likely to fail.
S.M.A.R.T.
A drive ____ is a duplication of everything written to a hard drive.
Image
_____ is a standard for communication between a subsystem of peripheral devices and the system bus.
SCSI
With ____, two hard drives are configured as a single volume.
Spanning
With _____, you can connect and disconnect a drive while the system is running.
Hot-swapping
A computer's ability to respond to a fault or catastrophe, such as a hardware failure or power outage, so taht data is not lost is known as _______.
Fault Tolerance
Each FAT entry lists how each ______ (or file allocation unit) on the disk is currently used.
Cluster
An extended partition can be divided into 1 or more _____ drives.
Logical
Track and sector markings are written to a hard drive before it leaves the factory in a process called _____ formatting.
Low-Level
To reduce the amount of electrical "noise", or interference, on a SCSI cable, each end of the SCSI chain has a(n) _____ resistor.
Terminating
Using both solid state and magnetic technologies
Hybrid Hard Drives
Moves the read/write heads across the disk surfaces in unison
Actuator
The overall structure an OS uses to name, store, and organize files on a drive
File System
A table on a hard drive or floppy disk that tracks how space on a disk is used to store files
FAT
The smallest unit of space on a disk for storing a file and is made up of one or more sectors
Cluster
A single hard drive that works independently of other hard drives
Basic Disk
Has no moving parts
Solid State Drive
Designed to provide greater security and to support more storage capacity than the older file system
NTFS
Speeds up access time by allowing blocks of data to be read from the drive at one time
Block Mode
