Improve Hard Disk Performance; Technology
This discussion is more focused on the myths surrounding the hard drive. These questions are still often questioned even on web forum discussions for specific topics specific hardware and hard drives. Rather than trying to find the following discussion one by one in cyberspace, this opportunity we try to summarize in this article. Which one is right and what is wrong with the myths that circulate about the hard disk? Here are a large part of what we share in some major categories.
Defragment Process and Hard disk
So far we recommend Windows operating system users, to perform defragmenting periodically. When doing this process, in addition to sometimes takes a long time (among others depending on the level of its defragment and free space on the hard drive), with the workload of the hard disk (and system) is quite high, sometimes raises concerns, whether the defragment process will shorten the life harddisk?
Shortening the Hard Drive Age
The defragmenting process is recommended periodically. There are fears of doing the defragment process will increase the risk of damage to the hard drive. Mainly due to the increased workload of the actuator head. The statement is true. Hard disk defragment process will indeed the burden, especially the process of going ongoing, to set the order of data on the hard drive. The positive side will be felt after the defragment process. With more regular data after the defragment process makes the hard disk decreased the amount of time required for seeking data. In addition to the performance improvements that will be obtained by users. So, it's true the defragmenting process loads a lot of hard disk workload during the defrag process. But with the advantage of the defrag process, which will usually last for a longer period of time than the old defrag process. In our opinion, the defrag process is still we recommend to be done periodically
Process Format and Harddisk
Quite a lot of assumption that connects the process of formatting the hard drive with the survival of the hard drive. Some of them contradict each other.
Shortening the Hard Drive Age
Formatting the hard drive is believed to shorten the life of the hard drive. This is simply not true. Formatting the hard drive is not an activity with the toughest workloads that handled harddisk. Even hard disk workloads in the process of formatting hard drives, is still much lighter, compared to when the Windows operating system began to access virtual memory. Some logical justification for this myth with the statement that the head movement in the formatting process is more active and complicated than the format process. On the contrary, in fact, the format process performs sequential movements, from sectors 500, 501, and so on. In fact, because the read / write head of the hard drive is not in contact with the platter physically, so there is no additional friction at all. Even extreme comparison, formatting every day even every hour even if not make your hard disk quickly damaged. Or at least will not be more quickly damaged than normal everyday use.

Bad Sector Emerges or Increases
After Format Process Some argue bad sectors on the hard drive can be increased after the format process. In fact, bad sectors on the hard disk will increase, depending on the type of damage that causes it. If the bad sectors on the hard disk caused by physical damage, both on the head and on the platter, then bad sectors will certainly continue to grow. Either without or with the formatting process, in fact, nothing at all has anything to do with the format process. Any process that is still done on the hard disk that has been "injured" is, of course, will add bad sectors. The only plausible reason for this myth is after the formatting process is complete, will display the format results report. One of them is the number of bad sectors. And when compared with the previous format process, will be seen the addition of the number of bad sectors. So more precisely, the format process will issue a hard disk status report, including bad sectors; and not specifically causing the increase of bad sectors.
Eliminate Bad Sector with Format Process
This is the opposite of the previous opinion. Some argue bad sectors will be repaired, by formatting the hard drive. Bad sectors are actually sectors on the hard disk that can not be used perfectly, both for the process of reading and write. For logical bad sectors, it can indeed be fixed by the process of formatting, or other utilities that are specifically able to fix this bad logical sector. Logical bad sectors occur usually due to errors in the read / write process by an application. Another case if not a logical bad sector. Say bad sectors physically, due to partial damage to the hard disk platter or often referred to as the physical bad sector. Physical bad sectors cannot be repaired either with special utility software, let alone just doing the formatting process. Except for certain types of hard drives equipped with a spare sector. The format process will mark bad sectors, and replace them with spare sectors, if they are available and still available on the hard disk. Physical bad sectors can be one of the first signs of damage to the hard drive. Can occur due to the head in physical contact with the platter, resulting in the emergence of platter splinters or part of the head. Although these fragments are very, very small, for a vacuumed hard drive, with minimal space and rotating platter, this will be very annoying. These small flakes will continue to be carried away by the rotation of the platter and may interfere with the balance while spinning, and very likely to collide with other hard disk parts.
However, if your hard drive does provide spare sector, it does not mean the hard drive in the prime state as usual. In most cases, bad sectors replaced with spare sectors have different tracks. Depending on the displacement of the difference in track difference, this will increase the seek time required for the actuator head while reading the data. So, besides it's good to pay attention SMART report from hard disk, hence the existence of bad sector can be used as an early sign to retire old hard disk. Especially if the hard drive in question used to store critical data. In some cases, it can be hard drive still long life, although it has been showing the signs in the span of say the year. However, if the stored data is really important, weigh the risks, it should not be done. No need to wait until the hard drive is completely inaccessible.
Periodic Format Process Can Increase Hard Disk Performance
Really hard disk needs to be formatted periodically to improve hard drive performance? Maybe you've heard about this, especially for the hard disk that is installed the operating system. For this, there is absolutely no logic to justify it. The hard disk format is completely unrelated to the increase in hard disk performance. Although based on experience, you feel the performance improvement of the hard drive after formatting after previous use for say two years. This is not a result of just doing the formatting process. For two years of use, a variety of data has been entered and exit on the hard disk. Depending on the size of hard disk capacity, file size and other variables; this is a bit much affect the data arrangement on the hard disk. Defragmented data on the hard drive to make hard disk performance more slowly. By doing the format, the hard drive is again empty, and the newly inserted files are not fragmented compared to the previous hard disk conditions. So, for business to improve hard disk performance, it would be more practical to simply defrag rather than having to move files to a temporary storage place to do the formatting process.

Periodic Format Process Can Increase Hard Disk Performance
Does hard disk need to be formatted periodically to improve hard disk performance? Maybe you've heard about this, especially for the hard disk that installed the operating system. For this matter, there is no logic that can justify it. The hard disk format is completely unrelated to the inexpensive hard drive performance. Though based on experience, you experience improved hard disk performance after formatting after previous use for say two years. This is the result obtained from. For two years of use, a variety of data has been entered and exit on the hard disk. Depending on the size of hard disk capacity, file size and other variables; this is a bit much. Defragmented data on hard disk. By doing the format, the hard drive is empty again, and the new files are not fragmented compared to the previous hard disk conditions. So, for business to improve hard disk performance, it would be more practical to do defrag the class should move to a temporary storage to do the process format.
Hard Drive and Electrical Painting
Ensure that PCs get a stable power supply and are free from any surge interruptions we always recommend, to achieve maximum performance and stable performance. This is also important for hard drives. Some of the myths that are true can damage the hard drive. More can be seen in the following description.

Hard disk and PSU
The decrease of voltage from power or power instability is one of the causes of bad sectors on the hard disk. Especially power supply that does not have sufficient output power. If a specific statement like this, which causes bad sectors on the hard drive, then this myth is not true at all. For hard drives, the actuator head is not physically in contact with the hard disk platter, under normal operational circumstances. Even if the hard drive will lose power, will not damage the platter or head actuator, and does not cause bad sectors. Noteworthy is, although the unstable power will not specifically cause the occurrence of bad sector, there are other risks.
A power failure may damage the circuit board and also damage the spindle drive motor on the hard drive. Two parts of this hard drive are more precisely will experience a negative impact of electrical instability or poor quality of output power from the power supply. Even at the worst extreme conditions, malfunctions on less-qualified power supplies can instantly shut down the hard drive and cannot function at all. Say when there is a surge (surge) cannot define later by the power supply.
Round Hard Drive and Power Pair
Still around the hard drive and electrical power, but a little more specific. It may be just a lap round unstable hard drive. There is the sound of spin-up acceleration, but the hard drive does not get enough power and fails to spin-up perfectly. Spin-down is not due to hard drive commands, but more due to insufficient power. Symptoms are spin-ups and spin-downs with a time lag or pattern, with no activity on the operating system, or earlier when a new PC boots. Actually, under normal conditions, spin-up and the spin-down process will only be done hard disk during the process of re-calibration. One of the causes of re-calibration is the obstacles that occur, which causes the size of data and data position on the hard disk will also change. Another cause of calibration is when the data on the platter cannot read perfectly. The same thing happens in optical disc drives, with a more audible sound. If this happens frequently on your hard drive, this is one of the early signs of the hard disk is not in top shape.
Electrical Flow and Hard Drive
Suddenly power out suddenly, without UPS then the desktop PC will not be powerless and necessarily immediately die. Some sudden electrical effects die, or in this case, if the PC is switched off (can be turned off power cable, PSU shut down) can cause bad sectors on the hard drive. This suggestion is true for hard disk a long time ago. When the hard drive head is still recommended to be positioned in park condition when the PC is turned off. Not for the latest hard drive, production in this decade period. Actuator head on the latest hard drive driven by the actual voice coil. Automatically, the head actuator will automatically position itself instantly to a secure position if the power drops to the hard drive are disconnected. So for a hard drive with voice coil actuator, the risk for this is very minimal. With time still driven by a stepper motor that still depends on mechanical functions. Paired power to a disconnected disc can suddenly make a stop in an unsafe position. The earlier hard drive was positioned in a park condition.
Rotating Platter Hard disk
The hard disk plates will only spin up during a read or write data and will spin off when idle. This is not right. Hard drive fixed in idle state. To restore the hard drive). The next question is, is it better to enable this spin down? The answer is no, especially for those who need the fastest performance. The hard drive does a spin-up on the PC boot. This spin-up process takes time and relative components in the hard drive a lot of activity. After the spin-up, practically the hard drive just needs to be reflected rotate the platter. If the hard drive has spin-down, it will take more time to prepare the hard drive to be ready to receive data. The hard drive needs to spin-up again and process the optimal speed, before ready to read/write process. Therefore, if desired the fastest performance of our hard drive to not activate the spin-down. However, activating the spin-down also has its own advantages. The hard drive will reduce its power consumption, this will also give a positive impact on the decrease in heat generated perperture. And a little more can advance hard drive endurance itself. So if you want those two things, pay attention to the PC usage style, and determine the pause time for the ideal spin-down.
Hard Drive Position
Different types of PC cases also provide the consequences of laying the hard disk diverse. There is a place for the hard disk horizontally, there are only provide the location of the hard drive.
Hard disk Horizontal Position
Some argue, placing the hard disk vertically for use in the long term will damage the hard drive. Highly recommended hard drive used in horizontal conditions. That opinion is equally incorrect. The latest hard drive can be operated, both in the horizontal position, vertical, even in fact. And it will not affect the age of the hard drive at all. What is not done is this, if the hard drive's hard drive hole is not available adequate air access. In any position, this will shorten the life of the hard drive.
