The main role of low-level formatting uses the following:
1, test the hard disk medium, do "bad" mark on the damaged track and sector
2, write into the sector ID, empty the sector content
If you look at the hard disk disk, it is a one, and each of them is divided into several blocks, each including the sector ID and sector data area. When low-level formatting, the low-grade software writes a sector ID and clear the data area at the beginning of each piece. When we use HP software to repair the hard drive bad sector, we will find that some sectors in the lower half of the wrong box are failed, and some have lost the sector ID, which can image the contents of these two parts.
3, set the interlaced factor
The hard disk's sector ID is not a sequence arrangement, but it will be like a few arrangements, why is this like this, because the hard disk is moving to the next fan after reading a sector When the location is not asked to read the content, it takes a time to stay, obviously, if the sector ID is arranged in order, if the actual situation is not in line with the actual situation, this, only the next sep sever, then arrange the next sector ID, this will More in line with hard drives. Of course, from the actual situation, the intersection of the hard disk will be set according to the different machine conditions. Sometimes it will make the crossover factor more suitable for your machine, thereby increasing the read and write speed of the hard disk. .
The correct low process will never be physically damaged, with incorrect low-skin tools may seriously damage the hard disk information, and the hard drive cannot be used normally.
