Part of hard drive

0 comments
As we all know hard drives are data storage and documents, and where System OS and application programs installed. Actually Hardisk can be classed with Memory, memory that is permanent, because the stored data and documents will not be lost after the computer on or turn off the switch.

Hardisk Inside there are several critical components, by knowing the components of this Hardisk we can better maintain our hard drive so that we secure documents and data stored on it. Because if you have important data, so if your hard disk is damaged then the data you also were damaged. But when the Mother Board or other components are damaged while the disk is not damaged, you can replace the other components and assemble your disks and data in it remains safe.

Here are some important components of hard disk:














Platter

Shape of a plate or disc which serves as data storage. Globular, a compact disc, a magnetic pattern on the sides are made of metal permukaanya.Platter that contain millions of tiny magnets, called magnetic domains domain.Domain-regulated in one or two directions to represent binary " 1 "and" 0 "

The disc is divided into several tracks, and some sectors, where the tracks and this is the place sctor data storage and file system. For example our hard drives with a capacity of 40 GB, when the format was not until 40 Gb capacity. because there must be a trac and sectors used to store the ID identifier of formatting the hard drive.

The number plate of each disk is different, depending on the technology used and the capacity of each disk-drive harddisk.Untuk latest output, usually a plate has a capacity of 10 to 20 Gigabyte.Contohnya a 40 Gigabyte hard drive capacity, usually consisting from two plates, each with a capacity of 20 Gigabyte.

Spindle

Spindle is a place to put platter.Poros shaft has a drive which functions to rotate the plate with a spindle drive which is called here the role motor.Spimdle participate in determining the quality of putaranya hard drive because the sooner, the better the quality harddisknya.Satuan means for measuring the velocity is Rotation Per Minutes or commonly called RPM.Ukuran that we often hear for the speed of this rotation include 5400 RPM, 7200 RPM or 10 000 RPM.

Head

This tool is used to read data on the surface of the plate and the plate dalamnya.Setiap record information to disk has two head.Satu above the surface and one below the surface.

Head is in the form of electromagnetic devices that are placed on the surface of the plate and attached to a slider.Slider attached to a stalk attached to the actuator arms arms.Actuator die mounted on the actuator shaft by a board called the logic board.

Therefore, when the hard drive is working there should be no shock or vibration, because the disk head can swipe your hard drive so will result in Bad Sector, and also can cause damage to the hard disk drive head can no longer read the Track and Sector of the hard disk.

Logic Board

Logic Board is a board on the hard drive operation, where the logic board so that the hard drive there are Bios hard disk when connected to the Mother Board automatically recognize the hard drive, such as Maxtor, etc. Seagete. Bios hard disk other than the place where the Logic Board also switch or Power Supply and distribution of data from hard disk to the mother-Head Board for ki control by the processor.

Actual Axis

Is the shaft for a handle or as a robotic hand that can be read sctor Head of the hard drive.

Ribbon Cable

Ribbon cable is the liaison between the Head with the Logic Board, where any document or data in the read by the Head will be sent to the Logic Board to the next in order to send to the Mother Board Processor can process data in accordance with the input received.

Conector IDE

Is the liaison between the hard drive cables with matherboard to send or receive data.
Right now the average hard drive is already using the system so it does not need the SATA ribbon cable (IDE cable)

Jumper Settings

Each hardis have jumper settings, functions for determining the position of the hard drive.

When we installed on the computer hard drive two pieces, then by setting Jumper setting where we can determine where the hard disk Primary and Secondary hard disk which is usually called the Master and Slave.

Masters is the main hard drive where the system is installed, while the Slave is the hard drive into two usually required for storage of documents and data. Jumper When the setting is not set, then the hard drive will not work.

Power Conector

Is a source of direct current from power supply. Power supply to the hard drive there are two parts:

1. Voltage of 12 volts, such as mechanical work to move the disc and the Head.
2. Voltage of 5 volts, the power function to mesupply Logic Board in order to work to send and receive data.

Thus on the hard drive, hopefully the information that I write to be useful to you.
