Understanding Hardisk

I want to post an article that aims to make you know what exactly the hard drive it, divided over how hard and hard parts. For more details, read the following article.

understanding Hardisk
Hard drive storage is designed to be used to save the data in a large capacity. This is a background application that does not allow programs to be in one disk and also require large storage media files such as a database

function Hardisk
• Notebook serves as a primary data storage on a computer or laptop
Types of Hard Drive

 

-          ATA
AT Attachment (ATA) is an interface standard for Menghu ¬ bungkan storage devices such as hard disk, CD-ROM, or DVD-ROM drive on the computer.
ATA stands for Advanced Technology Attachment. ATA Standard is managed by a committee named X3/INCITS T13. ATA also has several other names, such as IDE and ATAPI. Since the introduction of the latest version of the ATA called Serial ATA, ATA version is then called Parallel ATA (PATA) to distinguish it from the new version of Serial ATA.

-           SATA
SATA is the development of the ATA. SATA is defined as a technology that is designed to replace the ATA in total. Serial ATA adapters can accommodate data transfer speeds higher than a simple ATA

Notebook parts

platter
 Form a plate or dish that serves as a storage data.Berbentuk round, a compact disc, has a magnetic pattern on the flanks permukaanya.Platter metal containing millions of tiny magnets called magnetic domain.Domain-this domain arranged in one or two directions to represent the binary "1" and "0"

In this dish consists of some of the tracks, and some sectors, where track and sctor this is a data storage and file system. For example, our hard drives with a capacity of 40 GB, when the format was not until the 40 Gb capacity. because they have no trac and sectors used to store the ID is the identifier of formatting the hard drive.

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

Spindle
Spindle is a place to put platter.Poros shaft has a drive that serves to rotate the disk plate called a spindle motor.Spimdle whose role is involved in determining the quality the faster hard drive because putaranya, meaning the better the quality harddisknya.Satuan to measure the velocity is Rotation Per Minutes or referred RPM.Ukuran we often hear for the rotational speed of 5400 RPM, among others, 7200 RPM or 10000 RPM.

Head
This tool serves to read the data on the surface of the plate and the plate dalamnya.Setiap record information to disk has two surfaces head.Satu above and the other below the surface.

Head is in the form of an electromagnetic device that is placed on a surface plate and attaches to a slider.Slider attached to a handle which is attached to the actuator arm mounted arms.Actuator dead on the actuator shaft by a board called the logic board.

Therefore, when the hard work should not be any shock or vibration, because the head can swipe hard disk so that it will lead to bad sectors, and can also cause damage that Head Hard disk can no longer read the Track and Sector of the hard disk.

Logic Board
Logic Board is a board operating on the hard drive, which contained the logic Board Notebook Bios so hard when connected to the Mother Board automatically recognize the hard drive, such as Maxtor, Seagete etc.. besides the Logic Board Bios hard drive is also a switch or Power Supply and distribution of data from the hard drive to the motherboard Head Board for ki control by Processor.

Setting Jumper
 Each hardis has jumper settings, function to determine the position of the hard drive.

 
IDE connector
Actual Axis
 Is a shaft for a handle or a robotic arm that can be read sctor Head of the hard drive.—
Is the connecting cable between the hard drive with matherboard to send or receive data.

Ribbon Cable

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

Currently the average hard drive is already using the system so it does not require a SATA ribbon cable (Cable IDE)
When installed on a computer hard drive 2 pieces, then by setting Setting Jumper we can determine where the hard drive where the Primary and Secondary hard disk is usually called Master and Slave.
Master is the main hard drive where the system is installed, while the Slave is the second hard drive is usually required for storage of documents and data. When Jumper setting is not set, then the hard drive will not work.
Power connector
 Is a source of direct current from the power supply.— Power supply to the hard drive there are two parts:
1. Voltage 12 Volt, serves to move the disc and mechanical as Head.
2. Voltage of 5 volts, is used to power on the Logic Board mesupply to work to send and receive data.
