Defragmentasi HDD curtail the age of HDD
There are concerns do defragmentasi will increase the risk of damage to HDD. Especially to increase the burden of working head actuator. Defragmentasi process that will burden, particularly the progress prosess seeking to set the sequence data on the hard disk. Its positive effects will be felt after the new process defragmentasi, because the data more regularly, which makes hard disk to decrease the time for seeking the data. So defragmentasi HDD is still recommended for conducted regularly.

Most of the HDD to reduce the age of HDD
At the time formatting the head movement that more active than the non-format. The reality format to make the process of movement sequentially. Even as the head read / write is not in contact with the physical platter, so there is no friction at all. Formatted every day so it will not make your hard disk quickly broken.

Regular format can improve the performance of HDD
Format the hard disk regularly is not related to the increased performance of the hard disk. By doing format, kembalikosong hard disk, and files which new dimaskkan not terdefragmentasi compared to the previous condition. So to improve the performance of hard drives, more practical to simply make defrag from the format of the back.


PSU unstable voltage cause bad sector
If specific statements such as this; cause bad sector on the hard disk, the myth is not true. The need to consider is, even if power is not stable, will not be specific causes of the emergence of a bad sector, but there is still a risk the other. Ganguan ration power can also damage the circuit board spindle motor player's hard disk. Part two is more appropriate to be the negative impact from the output of electricity from the power supply. Even in the worst condition, can immediately turn the hard disk, for example, occurred without electricity hikes can be filtered by the PSU.

Bad because the electricity dead Sector suddenly
This is true but to the hard disk first period, when the hard disk head is still recommended utnuk positioned in the park when the PC is turned off. But not for the hard disk to date motor actuator Because the head with vocie coil actuator, which automatically reposition themselves immediately to secure the position of the ration power to the hard disk is lost.
I HAR different disk first period, which is still driven by stepper motor which still depends on the mechanical function.

Placing a vertical HDD can damage the hard disk

Opinion is totally not true. Hard disk can be operated in the latest horizontal and vertical, bakan even reversed. And the same age does not affect the hard disk. That is not done; breathing holes if the hard disk does not have access to adequate air exchange. In the position of any age will strike hard disk. Disadur from PC Media 09/2007

distroy the virus

Anti-virus is used to prevent inveksi by a virus or a scan / cleaner on the file system that terinveksi viruses / trojans / worms. Anti-virus software is the main defense against the viruses / trojans / worms. Anti-virus to be effective and up-to-date.
Why should install anti-virus software?
Without anti-virus we become very vulnerable / easily the vulnerable computer viruses, among others:
* Infection email attachment.
* Infection "Drive-by" to visit the website as corrupt.
* The virus that attacks through the Internet ( "Worms").
* Spyware is triggered by a viral infection.
* The virus is spread using the macro in the application document.
* Depending on the software you use, can detect some (not all) spyware.

Infected with the virus can cause serious impact, including:
* Theft personal data.
* Abuse.
* Loss of data.
* Computers that are slow or can not be used.

What is anti-virus software
Anti-virus software to protect various possible attacks:
* Men-scan incoming email containing the virus.
* Monitoring the file is opened or created to ensure that the files are not infected with the virus.
* Conducting periodic scan every file on the computer.

What anti-virus software does not do
Anti-virus software does not protect you up:
* The virus that does not have the characteristics / signature unique / signature.
* Programs that you may have to install the additional features that are not desired.
* Most spyware.
* Spam.
* Various kinds of abuse or criminal activity.
* Hacker who try to break your computer through the internet.

Anti-virus will not be useful if turned off for certain reasons and will not be very effective when its use is not often done perbaruan (update) to recognize the latest viruses. Signature of viruses such as a map of crime with the full characteristics penjahatnya. Each time a new virus appears, will do analysis and create a new bookmark to resurgent anti when the virus can block.
How to choose virulent anti-virus?
Good for personal use or for office there are many options
Personal / stand or Package?
Some companies stand to sell antivirus software developer programs that can be used for protection against the virus. For other package features such as firewall protection, spam filtering, anti-spyware and other.
In choosing the anti-virus there are several criteria to be considered:
* Price.
* Review the website that has a good reputation.
* Easy to use and not set.
* The level of quality technical support, including support website.
* Frequency and lkemudahan update.
Some commercial anti-virus, among others:
* F-Secure.
* McAfee.
* Symantec.
* Trend Micro.
Free anti-virus software
* Grisoft AVG Anti-Virus.
* AntiVir.
* ALWIL Avast.
* ClamWin.
Suggestions for prevention:
Do not open the file attachment from an unknown sender.
* Use protection macros in Microsoft Office, for instance, Word and Excel.
Do not forget to update regularly.
* Use only one anti-virus at the same time.
* Providing you update the virus signatures regularly, as a general rule, you do not need to buy every single new release of the anti-virus software to stay protected.
* Prevention is better than cure.

History of the Hard Disk Drive

Hard Disk Drive or frequently as we call 'the hard disk is only' one of the most important components in the computer. Hard Disk Drive has a name that called the general recording media that works to save data (information). Many of us use the hard disk, but may be very few people who know the origin of the Hard Disk Drive. Therefore in this forum I try to discuss the origin of the Hard Disk first.
Hard Disk Drive first created and produced by the IBM company in 1956 and then called the HDD as the first generation. HDD is the first found and created by Reynold Johnson. HDD is labeled RAMAC 305, which has a capacity of 5 Mega bits, or 5,000,000 bits and size 24 INCH and menggunakkan single head in pengaksessaanya.
In 1961 IBM created the HDD with menggunakkan head in each of the separate components of the data. Which is also called Disk Storage Unit Control System Meganical the International System. And the first HDD that can be removable (can be removed or installed again) is the IBM 1311, which uses IBM in 1316 to save 2 million characters.
In 1973, IBM introduce the IBM 3340, the first merupakkan HDD using the system disk "Whincester", the first sealed head / disk assembly (HDA). This technology designed by Kenneth Haughton.
Before 1980, most berurukuran 8 INCH HDD or 14 INCH, so many places need to save the HDD. Until the 1980s, when Seagate Technology mengenalakan ST-506, which is the first HDD-sized 5.25 inch, with a capacity of 5 megabites.
And even now, HDD capasita Terrabites reach 3.5 inch in size, so I below provides a timeline I can from a web of HDD development until now.
