Hard drive is one of the most important components in a computer, for
that you should be familiar with the type of hard drive according to the
conditions ana computer.
1. IDE
IDE (Integrated Drive Electronics) is a standard interface between a computer motherboard data bus with disk storage. IDE interface created by the IBM PC Industry Standard Architecture (ISA) 16-bit bus. Interface of the IDE is the interface for storage devices that can teringrasi to disk or CD-ROM drive. Although the IDE is a general technology, most people use the term to refer to the ATA specification. While
the AHCI (Advanced Host Controller Interface) is a hardware mechanism
that allows software to communicate with SATA such as host bus adapters
are designed for hot-plug and native command queuing (NCQ), which can
raise the ability of the computer / system / hard disk, especially in a
multi-tasking environment by
allowing the drive to perform read and write commands are sent at
random with a view to optimizing the head movement in the reading
process. AHCI has been supported by various operating systems such as Windows Vista and Linux kernel 2.6.19.
2. ATA
Most types of drives used by computer users is the type of ATA (known as IDE drives). Type
ATA made by standard 1986 using a 16-bit parallel and continues to grow
with the addition of transfer speed and the size of a disk. The
latter is a standard ATA-7 which was first introduced in 2001 by the
T13 committee (the committee responsible for determining the standard
ATA). Type ATA-7 has a data transfer rate of 133 MB / sec. then
during the year 2000 set the standard for parallel ATA has a data rate
of 133 MB / sec, but the parallel ATA there are many problems it singnal
thymine, EMI (electromognetic interference) and intergitas data. Then the industry in trying to resolve the problems caused by the
parallel ATA and created a new standard called Serial ATA (SATA)
ATA
(Advanced Technology Attachment) using 16-bit parallel is used to
control computer equipment, and has been in use for 18 years as a
standard. Differences SATA and ATA is easiest data cables and power are different.
ATA
standard, such as the 200GB Western Digital model, have a two-inch
ribbon cable with a 40 pin data connections and requires a 5V for each
pin of the 4-pin connection. Meanwhile,
120 GB SATA like western Digital Model has a half-inch wide, 7
connector so that the data connection is thinner and easier to manage
kebel data. SATA data cable has a maximum length of 1 meter (39.37 inches) longer than the ATA is only 18 inches.
3. SATA
With 15-pin SATA power cable with 250 mV, seems to require a lot more power in comparison with 4-pin ATA, but in fact the same. And the ability of the nicest SATA is possible to achieve maximum bandwidth of 150 MB / sec
Other advantages of SATA is SATA is made with hot-swap capability so
that it can turn off and turn without shut down the computer system.
Whereas
in the price, the more expensive SATA drives slightly compared ATA
drives, SATA kesimpulanya more have advantages over ATA connector,
power, and most importantly performance. ATA standard has now started on the left and the producers choose the SATA standard.
Parts Hard Drive
Posted on 13/10/2009 by dunkom
As we know the hard drive is the storage of data and documents, as well as a System OS and application programs installed. Actually Notebook can be classified in Memory, the memory permanently,
because data and documents stored will not be lost once the computer is
off or in offkan.
In
the hard drive, there are several important components, knowing the
components of this hard drive we can better preserve our hard drives so
that we secure documents and data stored on it. Because if you have important data, so if your hard drive is damaged, the data you also were damaged. But when Mother Board or other components damaged while the hard disk
is not damaged, you can replace the other components of your hard drive
and install it and the data remains safe.
Here are some important components of a hard drive:
Platter
The
shape of a plate or a disc that serves as a store data.Berbentuk round,
a compact disc, has the magnetic patterns on the sides
permukaanya.Platter made of metal containing millions of tiny magnets
called magnetic-domain domain.Domain This is set in one or two directions to represent a binary "1" and "0"
In
the disc consists of multiple tracks, and some sectors, where sctor
track and this is where the data storage and file system. For example our hard drive capacity of 40 GB, when formatted capacity is up to 40 Gb. because there must be trac and the sector that is used to store the identifier ID of formatting the hard drive.
Number
plates of each disk vary, 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 capacity of 40 Gigabyte
hard drive, usually comprising of two plates, each with a capacity of 20 Gigabyte.
Spindle
Spindle
is a place to put platter.Poros shaft has a drive which serves to
rotate the disk plate called a spindle motor.Spimdle this is
instrumental part in determining the quality of the disk due to the
faster putaranya, means the better the quality harddisknya.Satuan to
measure the velocity is Rotation Per Minutes or so-called RPM.Ukuran we often hear for the
rotational speed of 5400 RPM, among others, 7200 RPM or 10000 RPM.
Head
This tool is used to read data on the plate surface and plate
dalamnya.Setiap record information to the hard drive has two head.Satu
on the surface and the other below the surface.
Head is in the form of electromagnetic devices that are placed on the
surface of the plate and attaches 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 logic board.
Therefore, when the hard drive to work should not be any shocks or
vibrations, because the head can swipe the hard drive platters that will
cause bad sectors, and may also cause damage to Head hard drive so the
hard drive can no longer read the Track and Sector of the hard disk.
Logic Board
Logic
Board is a board operation on the hard disk, where the logic board so
that there is Bios HDD hard drive when connected to the Mother Board
automatically recognize the hard drive, such as Maxtor, Seagete etc. in addition to a hard drive Logic Board Bios also a switch or the
Power Supply and distribution of data from the hard drive to the mother
head ki Board for control by the processor.
Actual Axis
Is the axis to be a hand grip or as a robot that can read sctor Head of the hard drive.
Ribbon Cable
Ribbon cable is the link between Head Logic Board, where any documents
or data that are read by the Head will be sent to the Logic Board
henceforth be sent to the Mother Board so that the processor can process
the data according to the input received.
Conector IDE
Is a connecting cable between the hard drive with matherboard to send or receive data.
Right now the average hard drive is already using a system that does not require a SATA ribbon cable (IDE Cable)
Setting Jumper
Each hardis has a jumper setting, its function is to determine the position of the hard drive.
When our computer hard drives installed 2 pieces, then by setting
Jumper settings we can determine where the hard drive where the Primary
and Secondary hard drive 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 Jumper settings are not set, then the hard drive is not going to work.
Power Conector
Is a source of direct current from the power supply. Power supply to the hard drive has two parts:
1. Voltage 12 Volt, serves to move the mechanical such as disk and Head.
2. Voltage 5 Volt, serves to power the Logic Board mesupply to work sending and receiving data.
Thus, hard drive, I hope that I write this information can be useful for you.
an example of the hard drive that I use for practice, click on the image if you want to clarify
Drive capacity will be in use at least 40 GB (let you ndak useless to purchase additional hardware) the reason, if the hard drive of your used which would be made externally only has a capacity of 5 GB to 8 GB, yes mending buy flash bro and sis bra, soale price FD with a capacity that is reasonably priced, most cuman 80 rb (IDR) wrote for the 8 GB, but the price depends on the brand is also an additional sih.Hardware:
You should look for tools that called IDE SATA to USB converter costs about 45 thousand or less anyway, this tool consists of two parts that you can see in the picture below
