Heart On Computer

Hard drive is one of the constituent components of a PC (Personal Computer). Hard drive belonged to a hardware or computer hardware compilers other than motherboards, memory, VGA, and other hardware. The function of a hard disk in a computer is as important as other computer hardware compiler. Some call that the hard drive is the heart of a computer.

Hard disk or hard drive is often called has meaning as a primary storage device on a computer. Harddisk first created by an IBM engineer named Reynold Johnson in 1956. Harddisk contains magnetic disks that hold the data. Data storage in the hard disk will not be disturbed if the computer is turned off. So, in general serves as a data storage drive in a long period of time. And this is the cause of the drive called a heart on the computer.

First created, the hard drive can only store 4.4 MB of data. However, developments in computer technology was super quick to make hard drive capable of storing up to 3 TB of data (terabytes). From year to year, the hard disk capacity increases, ranging from the smallest to the largest. For now, the market is a computer, the hard drive has outstanding size above 100 Gigabyte.



Hard parts
Hard drive as a data storage have parts that are interrelated to each other. Here are the parts of the hard drive.

1. Hard Parts - Spindle
One of the authors is a spindle drive. In hard disks, the rotation of the spindle at the center of the discs that save the data. As part of the disk, the spindle will move very quickly. So, it should use high quality bearings.

First, the hard drive using a ball bearing. But now, the development of computer technology requires hard switch use the fluid bearing. With fluid bearings, the noise level can be minimized hard drive. Spindle function to determine the velocity of the hard drive. Thus, if the velocity of the faster hard drive, then the process of data transfer to and from the hard drive will be faster.

2. Part Harddisk - Magnetic Disc
Data storage in the hard disk made in this section, magnetic discs. Magnetic discs as part of the components of the hard drive is a thin plate shaped like a CD. In a hard drive, there are several magnetic discs.

Harddisk is first created consisting of 50 magnetic discs with size 0.6 feet and has a spin speed of about 1,200 rpm. Nowadays, as the development of computer technology, including the development of the hard disk, magnetic disk speed on the hard disk today can reach 10,000 rpm so it can transfer data at up to 3.0 Gbps.

3. Part Harddisk - Read Write Head
One of the components in the drive is a read write head. Part of this hard work retrieving data from magnetic disk. Part of this hard drive is above the magnetic disk with a thin floating position. Previously, the hard drive is in direct contact with the magnetic disk drive. The touch between the two parts of this hard drive cause wear and tear on the surface due to friction.

Read Write Head as part of the disk is made of material over the years has developed more advanced. The materials commonly used mainly as a maker wrirte read head as part of the hard drive among others Ferrite head, MIG (Metal-In-Gap) head, TF (Thin Film) Head, (Anisotropic) Magnetoresistive (MR / AMR) Heads, GMR (Giant Magnetoresistive) Heads. Now, the hard part is often made using materials CMR (Colossal Magnetoresistive) Heads.

4. Part Harddisk - Enclosure
Enclosure is one of any part of the hard drive. Hard part is the outer layer of the hard drive. Enclosure as a constituent part of this hard drive has a protective function as other parts of the hard drive being exposed to dust, moisture, and other things that DAPT led to damage existing data on the hard disk.

In the section called hard disk enclosure, there is a section called breath filter. This section makes the hard drive to be airtight. It has a goal to throw the hot air in the disk resulting from the operation of the spindle and the read write head.

5. Part Harddisk - Interfacing Module
Components in the other hard drive is Interfacing Module. Interfacing Module as part of this disk-shaped series of electronics that regulate the function of the hard work, process the data from the head, and produces a set of data generated in the process.

First, Interfacing Module is a system that is widely used IDE (Integrated Drive Electronics). The system uses IDE ATA system. The new system of Interfacing Module is a SATA hard drive. With SATA technology, hard drive DAPT dealt with quickly and efficiently. Lately, SATA systems have replaced the hard drive where the hard drive with ATA technology.

Causes Damage to Hard Drive

Hard drive as the storage medium and long-term permanent data could be damaged. Here is the cause of damage to the hard drive.

1. Causes Damage to Hard Drive - Off The Sudden
Death of power surges or sudden power failure will result in damage to the hard drive. Moreover, if the frequency of power failure or power outages were frequent. Thus, if the flow of electricity in your home often experience sudden or frequent outages lights off, need to be careful with the condition of your hard drive. In addition, a sudden power failure could damage other electronic items.

The solution to this problem, you can add accessories such as a computer UPS. This tool serves to save electricity. If your computer is using UPS and if the power goes out suddenly, your computer will stay on as UPS continues to supply power. However, electricity is generated UPS lasted less than 1 hour. So, if you are using this accessory, your computer, especially the hard drive will be maintained condition.

2. Causes Damage to Hard Drive - Often Perform Reset
Perhaps, some of us think that the reset will not affect much on the computer, especially the hard drive. However, keep in mind that often reset the computer will cause the computer is damaged, particularly hard.

Why does this happen? Because when the hard drive is working, hard needles are in the middle of the disc drive. So, if you do the reset on the computer, the position of the needle on the disk will be immediately moved down and left scratches on the disk. This can lead to bad sectors on the hard disk.

Any tips if you want to reset the computer. If the computer hangs and there is no other way to turn it off, you are forced to reset the way. Well, before reset, wait for the hard drive indicator light (usually red that can be seen from outside the CPU) does not flash or hard drive indicator light is off. If the hard drive indicator light does not blink or light up, press the reset button to do.

Tips on Caring Harddisk
Here are tips for caring for hard disk drive in order to remain durable and safe from damage.

Use stabilizer or UPS on your computer. Stabilizer or UPS serves as a store of electricity when a power outage occurs while the unexpected. So, with the stabilizer or UPS, your computer does not immediately die.
Perform back up the data on the hard drive. This is done to avoid things that are not desirable if your hard drive is damaged.
Install antivirus on your computer. Ways to reduce the risk of the hard drive and the computer virus.
Perform disk maintenance programs, such as Disk Defragmenter.
Remove or uninstall applications that are not used. This will speed up working hard.

Manufacturer Hard Drive Brands
Competition computer hard drive on the market is extremely tight. This is because many companies that produce hard drives. Here is a company that produces hard drive.

Seagate.
Maxtor.
West Digital.
Quantum.
Samsung
