The hard disk is generally necessary to use: Low-level formatting → Partition → Advanced formatting three steps. The low-level format is generally the hard disk manufacturer, it has been completed, and ordinary users only use other tools to partition and advanced formatting, but sometimes we need to format hard disk low-level, to fix some big bad sectors, Small hard drives do not recognize the problem of unable tools. Generally speaking, if a physical failure of the hard disk is difficult, there is a method worth trying, that is, low-level formatting. The low-level formatting effect is to divide the blank magnetic sheet one by one with a different circle, a radius, and divide the track into several sectors, each sector having a capacity of 512 bytes. In case of the following cases, low-level formatting may be necessary: 1 is lost by external strong magnets, strong magnetic fields, or due to long-term use, the hard disk magnetic distribution is lost by low-level formatting, and therefore A large number of "bad sectors". Note that this is not physical damage to the magnetic sheet. At this time, low-level formatting, re-dividing the sector, may be a valid approach. 2 To improve the performance of the hard disk, try to reset the sector "interleave" (interleave) to increase the speed of reading and writing, re-performing low-level formatting is usually used. Of course, there are some software such as the Calibrat (Norton Utilities for DOS 8.0 Chinese version in Norton Utilities for DOS 6.0-8.0) to optimize intervals, improve the hard disk for low-level formatting operations that do not damage data speed. Now let's take a step in step by step to see why low-level formatting. First, download a LFORMAT.EXE first, this program can only be used for DOS mode, which cannot be used on Windows DOS window. Step 1: Go to the directory where the program is located, or a disk, perform LFormat. The following screen: The meaning of these words is: do not promise: This tool does not have any clear or suggestive guarantees, therefore causes any damage to those useful or stored, it is not matte It doesn't matter if developers do, Mai Tuo is not clear or implied, and its software does not reach its ability to damage. Mai Tuo's update to its software is not guaranteed separately. Warning: Use this software will make all the information on this disk is all lost, please back up all your data before using this. Mai Tu recommended that you unplug all other disks before playing this stuff. (In order to fire in the city. However, the floppy disk cannot be pulled, otherwise what partition and high.) When you use the "Y" button, you start this program, other keys exit. Step 2: When we press the "Y" button: It means: Select the drive disk low-grade current drive to exit the help window: Use the arrow keys to select a one you want, then press Enter key Or return the third step: When we select the first and enter the bus, a red dialog will pop up.
The following screen appears: Select the drive disk low-handed drive exits the information window: Which drive (0, 1, 2, 3) Help window you will choose: Use the arrow keys to select an action you want, then press Enter or Back Note: There are two IDE interfaces on the general motherboard, up to four hard drives, (of course, SCSI's and now the new motherboard can be different), it is different.) Generally, we are all IDE interfaces, Another IDE interface light drive. And a hard disk cable has two interfaces, so there are four options, but starting Mai Tuo company warned, it is best to pick up a low hard drive, because he is afraid that if you have several hard drives in the machine I accidentally selected one. However, as long as you carefully see the instructions, you will pick a few hard drives, and you will not be wrong. Nowadays, it is the first time, so I will choose one, and all everyone thinks that everything starts from 1. The fourth step is there. Step 4: When we are selected from the four prodes of (0, 1, 2, 3). The following screen appears: Select the drive disk low-handed current drive to exit the current drive is: 1 model #: no serial number: #: No chip: No cylinder: 0 heads: 0 sector: 0 Maximum logical area: 0 Help window : Use the arrow keys to select an action you want, then press the Enter key or return (this window is not what we want, because it seems to be 0, the model is: No. I said that we find the wrong. Don't tighten, then, let's press the ESC button to withdraw one, choose the first content, this time we choose 0 to see, the fifth is not a picture.) Step 5: We started to choose 1 seems to be, So we selected 0. The following screen: Select the drive disk low-hard current drive Exit The current drive is: 0 model #: ibm-dtla-307020 serial number: #: YHOYHF31775 chip: TX30A50C cylinder: 16383 head number: 16 sectors: 63 maximum logical area : 40188959 Help window: Use the arrow keys to select an action you want, press the Enter key or return (from this window, there should be something we want, the drive is 0 model is the product, capacity of IBM 20G 2M cache, 7200 revolutions (taking such a good Dongdong doing test, respectable), other serial numbers, chip version, each company is different, the following, the number of cylinders: magnetic head, fan District, maximum logical area, etc., this is not the scope of this explanation. After found, we use the arrow to select the second option, the low-grade drive. There is a picture below.
