For a computer user, the word "formatting" should not be unfamiliar. Disk formatting is also one of the most important disk functions. The meaning of formatting is to divide a blank disk into small areas and number them for computer storage, reading data, and unformatted disks. It is not working properly.
According to the formatting function, it can be divided into low-level formatting and advanced formatting. However, because low-level formatting is a last resort and has great damage to the hard disk itself, Most of the time we won't use it, but if the hard drive has to perform a low-level format operation, how does it work?
Why low-level formatting?
First we have to figure out what is low-level formatting. The low-level format is to divide the blank disk into the cylinder and the track, and then divide the track into several sectors, and each sector is divided into the identification part ID, the interval area GAP and the data area DATA. Before the hard disk leaves the factory, the engineers will perform a low-level formatting on the hard disk. When the hard disk has some type of bad sectors, the low-level formatting can be used to relieve or block the hard disk.
What is the impact of low-level formatting?
It should be noted that in the previous level of disk reading technology, low-level formatting is a lossy operation, which has a certain life on the hard disk. Negative impact. The hard disk's low-level formatting effect in the last one or two years is much smaller because it is not a physical operation. Therefore, many hard disk manufacturers recommend that users do not have to, and can't "妄” make this move. When the hard disk is affected by external strong magnets, strong magnetic fields, or due to long-term use, the magnetic recording portion of the sector format divided by the low-level format on the hard disk is lost, so that a large number of "bad sectors" can be passed through the low level. Format to re-divide "sectors". But the premise is that the platter of the hard disk is not physically scratched.
How to perform low-level formatting
At present, to format the hard disk at a low level, you can use the tool. Like the lformat.com program low-grid hard drive, DM tools are very good, and more easy to use, can also be used directly under XP system. And if there is no tool, you need to operate directly in COMS. The specific process is as follows: Enter CMOS Setup according to the system prompt when booting (if it is BIOS such as Award, you will be prompted to press DEL to enter CMOS Setup, if it is Intel motherboard, press F2 to enter CMOS Setup), then select low formatted in CMOS menu. HardDisk Drive selects, then according to the program prompts to wait for the low-level hard disk, and answer some program questions to perform low-level formatting of the hard disk.
A friend who wants to perform low-level formatting should pay attention to the fact that since it is formatted, it is more difficult to recover the things inside, so it is still prudent to use it, and it is not recommended at the last time. Still try not to use this method. Finally, I would like to remind you that low-level formatting has a certain negative impact on the life of the hard disk, please use it carefully.
