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
