Formatting the hard disk (not low-grid) will affect the hard life?

Common format the hard drive will not affect the life of the hard disk. Format is divided into high-level formatting and low-level formatting. Advanced grid ..Formatting the hard disk (not low-grid) will affect the hard life? Format the hard disk with Windows on a floppy disk formatted with the principles of the same? Answer 1: General formatting the hard disk will not affect the life of the hard disk. 

Format is divided into high-level formatting and low-level formatting. High-level format just clear the hard disk data, generating guide information, initialize FAT table, mark the logical bad sectors and so on. The low-level formatting the hard disk is divided into a cylinder and track, and then track divided into several sectors, each sector has carved out some identity ID, spacers, GAP, and data area DATA and so on. High-level formatting low-level formatting is the work of the previous one, each disk in the factory before they had low-level formatting. 

Low-level formatting is a loss of operations, the hard life of a certain negative impact. We usually used by Windows, formatted (including the use of DOS format below) is high-level formatting. In Windows, the formatting of the hard disk and floppy disk formatted principle is the same. The floppy disk format is different, we carried out a comprehensive format a floppy disk is a low-level formatting. Answer 2: For the past few years bought a new hard drive, including high and low grid, including cell formatting operation will not affect their life. 

Compared with the previous, and now the hard disk's physical structure has undergone some changes directly affect the realization of the corresponding changes in the way the hard disk commands, the most important thing is to seek changes in the way the hard disk led to changes in the formatting instructions. Currently users can access is through the transformation of the logical sector, rather than the actual physical head corresponding to the physical sector. In this way, the user can not actually drive the physical sense to operate the. 

Now the so-called low-level formatting is only achieved a re-set to zero and will redirect the bad sector fills and can not be achieved the hard disk regeneration, there is no physical sense of the repair. For the commonly used high-level formatting, "Quick Format" is just to reset the hard disk partition table, even the "full format", is nothing but reset the hard disk partition table in addition to all sectors to re-set to zero. It can be seen, the user is running with the other common formatting commands to read and write operation is not fundamentally different, and in the entire life of the hard disk, this number of read and write can only be measured with an astronomical figure, and formatting, or Ghost in the number of operations can be ignored. Under the existing hard disk manufacturing technology, general applications, simply because the hard disk damage caused by reading and writing is very rare, most drive failures are related to external physical impact, read and write in a sudden power failure, as well as damage to the circuit. 

Therefore, the only format to be considered is to avoid the occurrence of these types of situations. Was the same as the floppy disk drive, using stepper motors to control the head position to seek operation. As mentioned in front, now, with the level of head positioning precision constant improvement of methods and formatting the hard drive seek instruction, great changes have taken place. However, in normal circumstances, the actual applications, we can consider the two principles are the same.
