Parts of the Disk

As we know the hard drive is the storage of data and documents, as well as the system OS and application programs installed. Hardisk actually be in the grade with a Memory, memory that is permanent, because the stored data and documents will not be lost after a system failure.
In the HDD, there are several critical components, by knowing the components of this Notebook we can better preserve our hard drive so that we secure documents and data stored on it. Because if you have important data, so if your hard drive is damaged then the data you also were damaged. But when Mother Boards or other components are not damaged while the hard drive is damaged, you can replace the other components and install your hard drive and the data in it remains secure.

Here are some important components of the HDD:



Platter

The shape of a plate or dish that serves as a store data.Berbentuk round, a compact disc, a magnetic pattern on the flanks of permukaanya.Platter made of metal that contains millions of tiny magnets, called the magnetic-domain domain.Domain This is set in one or two directions to represent binary "1" and "0"

The disc consists of several tracks, and some sectors, where track and sctor this is where the data storage and file system. For example our hard drives with a capacity of 40 GB, when the format is its capacity to 40 Gb. 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 hard-disk harddisk.Untuk latest output, usually a plate has a capacity of 10 to 20 Gigabyte.Contohnya a 40 Gigabyte hard drive capacity, 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 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 so-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 serves to read data on the surface of the plate and record information to the hard drive dalamnya.Setiap plate has two head.Satu above the surface and one below the surface.

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

Therefore, when the hard work should not be any shock or vibration, because the head can swipe a hard disk so that it will lead to Bad Sector, and can also cause damage to hard drive so the hard drive head is therefore at the time of hard work should not be any shock or vibration, because head can rub hard disk so that it will lead to Bad Sector, and can also cause damage to Head Hard disk so it can no longer read the disk track and sector of the hard disk.

Logic Board

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

Actual Axis

Is the axis for a handle or as a robotic arm 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 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 received input.

IDE connector

Is the connecting cable between the hard drive with matherboard to send or receive data.
Right now the average hard drive is already using the system so it does not require cable SATA Tape (Cable IDE)

Jumper Settings

Each hardis have jumper settings, its function is to determine the position of the hard drive.

When we installed on the computer hard drive 2 pieces, then by setting jumper settings we can determine where the hard drive where the primary and secondary hard disk is usually called the 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 the jumper settings on the Master is not 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 the jumper settings are not set, then the hard drive will not work.

Power connector

Is the current source directly from the power supply. Power supply on the hard disk there are two parts:
Voltage 12 Volt, serves to drive the mechanics such as dish and Head.
5 V, serves to mesupply power on the Logic Board to work to send and receive data.

Thus on the hard drive, may I write this statement can be useful for you.
