屏蔽掉硬盘的坏扇区 How to shield the bad sectors of the hard disk? Hard to use for a long time, there will be a variety of problems, while the hard disk "bad sectors" is one of the most common problems. If the change in the warranty period, you can get the hard disk vendor source replacement, and three period and how to do it? The following is the author's maintenance and maintenance of some of the hard disk, and hope to help you repair the hard disk. A hard disk has bad sectors, threatened Hard disk is divided into logical bad sectors and physical bad sectors two kinds, the former is usually soft bad sectors, improper operation or use of the software, software available for repair; the latter is the real physical bad sectors, it shows that you have a hard disk track physical damage, can only be solved by the use of hard disk partition or sector change. The following conditions maybe your hard disk has bad sectors: First of all, you run in the open, or a hard copy of a file operation is slow, and there may be a long time operation is not successful or for long time to die "bite" one area or at the same time appear hard to read the disk noise, or simply Windows system prompts unable to read or write to the file. These can show that a part of your hard disk bad sectors. Secondly, every time you boot Scandisk disk, the program automatically, must show important errors need to fix your hard disk, such as bad sectors. You are running the program if not passed, that must have the hard disk bad sectors. Of course, although it can be through the scan, but the red "B" mark, that there are bad sectors. Third, the computer starts when the hard disk can not boot, with a floppy disk or CD-ROM boot after the hard disk drive can be seen but not in the area of operation or misoperation or simply do not see the letter, that may appear on the hard disk bad sectors. The specific performance such as boot process, the screen shows "Hard disk drive" Hard drive failure "controller failure" or similar information, it can be judged for the hard drive or hard disk controller failure; hard disk read and write prompt "Sector not found" or "General error in reading drive C" and other similar error information indicates that the hard track appeared physical damage. Finally, the computer crashes or problems "the corrupted files" in normal operation, but also may be related to hard disk. Two, hard disk maintenance Scandisk ScanDisk is hard to solve logical defects most commonly used tools, and our common format commands not to repair any effect on the hard disk, you need to understand this. If the hard disk bad sectors, we can be in the Windows system environment, selected to deal with the hard disk drive in my computer, choose the "properties" in the "tools" button to select "check", click "start check", then "scan type" selected "comprehensive inspection", and "automatically fix errors" marked "hook", then "start" can, it will complete the hard disk scan, and the possible bad clusters do automatic correction. Secondly, under the condition of DOS, the hard disk has bad sectors, When the computer starts, it usually scans the Scandisk automatically and identifies the broken clusters with the "B" (bad) of the black background. Of course, if the system does not start in the disk scan or can not enter the Windows system, we also use a floppy disk or CD-ROM and boot the computer, in the corresponding letter, such as "A:" run Scandisk *: (Note: * in order to scan the hard disk drive), then enter the corresponding scan the hard disk partition repair repair. The most commonly used methods such as other Norton toolbox in NDD "Disk Doctor" and Pctools and other tools for scanning and repair hard disk on the hard disk, its usage is very simple, many newspapers are introduced, we can try to find. If the hard disk has been unable to repair bad clusters or physical bad sectors, we used some of these software disk bad sectors into a separate area and hidden, so you can make hard to extend the service life. Method: as a 4.3G hard drive at 2G have serious physical bad sectors, formatted with format does not survive, but also through the detection of Scandisk or NDD, but normal partition. Find a partition formatted Smart software Fdisk, and boot the computer, enter the letter: A, run the executable file of the software SFdisk.EXE (DEL); and then delete the original partition, calculate the bad sectors on a hard disk location. In the case of this example, to establish the basic partition of 1990M, fast after formatting and activate it, then put out a logical partition about 50M dispose of bad sectors, and then a logic region with the function of quick format quick format hard disk space as the left; finally will delete that about 50M of the bad sectors it is the area (DEL). And then restart, a serious physical bad sectors hard disk will soon be repaired after the head, don't read those deleted bad track zone. Method two: the Fdisk partition comes with the Windows system. For example, a 1G hard drive, can not pass in the format to 10%, then press Ctrl+Break forcibly terminated, run Fdisk 90M to build a DOS partition for C, then establish a 20M logic D, then M is more than 800 the rest of the establishment of a logical disk E. Quit Fdisk and run format E: if the grid to 10%, and encountered obstacles, then use Fdisk to build a 88M E disk, 10M F disk, and the remaining 790M as G disk. Continue to repeat the above operation until completion. Then, Fdisk will run 10M D F disk, delete, then the rest is not good disk bad sectors. Method three: by the same token, using PartitionMagic, DiskManager and other disk software can also do such work. As PartitionMagic partition software, using ScanDisk PartitionMagic4 in the "check" command or Windows to scan the disk position, calculate the bad clusters on the hard disk, and then select "Advanced/bad Sector Retest" in the Operations menu; the bad clusters where the hard disk is divided into a plurality of areas, then the bad cluster partition hide, avoid misoperation in Windows, this function is through the Hide Partition menu item to achieve. It can ensure the normal use of serious bad sectors hard drives, and remove the system frequently to read and write bad sectors to expand the area of bad sectors. The system displays "TRACK 0, BAD, DISK, UNUSABLE", meaning "zero track damage, hard disk unusable", or "0" red "B" when ScanDisk scans other hard disks". Hard disk 0 sector damage, is a headache compared to everyone, usually people will appear in this case of hard disk for scrap treatment. In fact, the rational use of some disk software, the scrapped 0 sectors shielded, and replaced by 1 sectors can play a life back effect, such software, such as Pctools9.0 and NU8. Method 1: let's take Pctools9.0 as an example. A 2.1G hard disk appears the fault, start the computer with the disk and run the DE.EXE file under the Pctools9.0 directory. Then select the Drive in the main menu Select, go in, select the Drive in the type Physical, select the blank space, press the Tab key to switch to the Drives item, select hard disk, and then return to the main menu after OK enter. Open the Select menu, then there will appear Partition Table, select the hard disk partition table information after entering. The hard disk has two partitions to find the C zone, which starts from the 0 cylinder of the hard disk. Then, change the 0 Beginning Cylinder of the 1 partition to 1, and save and exit. When you restart your computer, press Del to enter the COMS settings and run IDE AUTO DETECT. You can see that CYLS is changed from 782 to 781. Save after exiting and reformat the hard disk to bring it back to life. Method two: Norton NU8.0 is also good. For example, a 1.28G hard disk 0 track damage fault, enter the NU8 toolkit directory, run the main program NORTON.EXE, then select "remedial disk" RESCUE option to backup the information of the hard disk boot partition table, etc.. Then select the "disk editor DISKEDIT", after the successful operation of "object OBJECT", choose "the hard disk parameters are visible after the partition table": surface SIDE 0-63, cluster CYLINDER 0-255, sector SECTOR 1-63, the master boot record and partition table information should be in the 0 column of 1 sector 0. We have to do is take the starting sector C from 0 0 to 0 1 sector column 1 column 1 sector, move the cursor can be modified manually. Also, what you need to say is that the change is based on the specific circumstances. Finally, after the disk is saved, restart the computer and use the format command to format the hard disk for normal use. Special attention should be paid to, after the repair of the hard disk must not use DOS under the Fdisk and other partition tools to re partition operations, so as not to change the hard disk's starting cylinder. If all the strokes are not effective, then we have to use the onboard hard disk or hard disc manufacturers with the grid program presented grid programs such as DM, Lformat and so on HD low-level format, it can be some bad sectors hard to rearrange exclusion. Three, how to use the right to reduce the occurrence of bad sectors The above said so much, a little too late, The correct use of the hard drive is to reduce the hard disk damage occurrence, the best way to improve the service life of the hard disk. 1. hard disk can not work suddenly shutdown When the hard disk starts working, it is usually in high speed rotation. If we suddenly turn off the power on the way, it may cause the head and disk to rub violently and damage the hard disk. Therefore, we should avoid sudden shutdown. Shut down, must pay attention to the panel on the hard disk indicator light is still flashing, only in its lights stop blinking, hard disk read and write before the end of the computer power switch. 2. prevent dust from entering Dust damage to the hard disk is very large, this is because in the dusty environment, the hard disk is easy to attract dust particles in the air, the long-term accumulation in the internal circuit components on the hard disk, will affect the electronic components of the heat, the temperature rise of circuit components, resulting in leakage or burn out components. In addition, dust may absorb moisture, corrosion of electronic circuits inside the hard disk, causing some puzzling problems, so the dust size is small, but the harm to the hard disk can not be underestimated. Therefore, environmental sanitation must be maintained to reduce moisture, humidity and dust content in the air. Remember: the average computer user can't disassemble the hard disk cap, otherwise the dust in the air goes into the hard disk and scratches the disk or head when the head reads and writes. 3. to prevent the temperature is too high The temperature also affects the life of the hard disk. Hard work will produce a certain amount of heat, the use of heat problems. The temperature is at 20~25 degrees, and too high or too low will change the clock frequency of the crystal oscillator. The temperature will cause the failure of the hard disk circuit components, and the magnetic medium will cause the error due to the thermal expansion effect. When the temperature is too low, the moisture in the air is condensed on the integrated circuit components to cause short circuits; Humidity is too high, the electronic components surface may be adsorbed water layer, oxidation and corrosion of electronic circuit, so that the poor contact, even short circuit, will make the magnetic force of magnetic medium change, cause data read and write errors; the humidity is too low, easy to accumulate a large number of rotating machine for static charge generated, which burn CMOS circuit, dust absorption head, scratch disk damage. The humidity in the engine room should be between 45 and 65%. Pay attention to keep the air dry or often to power the system. It evaporates steam from the engine by itself. In addition, try not to make the hard disk near the strong magnetic field, such as speakers, speakers, motors, radio, mobile phones, etc., so as to avoid the data recorded by the hard disk damaged by magnetization. 4. regularly organize the information on the hard disk In the hard disk, frequently create and delete file will cause a lot of debris, debris accumulated more, in the days after the access to a file, the hard disk may take a very long time, not only access to lower efficiency, but also may damage the track. To do this, we should always use disk defragmentation in Windows 9x systems to defragment the hard disk. After finishing, it's best to use the hard disk repair program to fix the tracks that are in trouble. 5., regular anti-virus on the hard disk Now viruses are becoming more and more widespread, while hard disks serve as computer information storage bases, It is usually the target of its attack. Each year in April 26th, every computer user has a lingering fear, the author's several hard drives on the unit were brutally attacked by CIH. Therefore, in order to ensure the safety of the hard disk, we should pay attention to using the latest antivirus software to kill the virus, while paying attention to the protection of important data and regular backup. 6. take care of your hard drive with your hand In daily computer maintenance, it is very frequent to use the hand to hold the hard disk. Perhaps the most common thing, most of all, does not attract our attention. In fact, the use of hand to hold the hard disk is still learned, a little careless will make the hard drive "scrapped", so when we use the hand to hold the hard disk, we must do the following two points: The tohandlegentlyand, don't bump or other hard object collision; Cannot touch the circuit board on the back of the hard disk by hand. This is because the climate is dry, the body usually with static electricity, in this case touch the hard disk on the back of the circuit board, it is likely to damage the human body electrostatic electronic components on the hard disk, the hard disk can not lead to the normal operation. Therefore, we should seize both sides of the hard disk while holding the hard disk and avoid direct contact with the circuit board on the back. Some types of hard disk will be a layer of cuticle in the external package, it has shockproof function, the protection of the circuit board, so we don't have to worry about what the electrostatic. 7. try not to use hard disk compression technology We used to try hard to save hard disk space when our hard disk space was small. For example, the common measure is to compress hard disk space through Doublespace and Drvspace commands. But when compressed volume files gradually increase, this method has one obvious drawback, that is, the read and write data of the hard disk is greatly slowed down. With the rapid development of the technology of hard disk, the disk capacity is also rising, the current market popular hard disk space is about 20G, it is hard to appear before the kind of hard disk space is not enough for the situation, so we do not need to use the hard disk compression technology. 8. cannot move the hard disk in the work The hard disk is a high precision device that operates with magnetic heads only a few microns across the surface of the disk. When the hard disk is in the read-write state, once the big vibration occurs, it may cause the head and the disk impact, causes the damage. So don't move the running computer. Should be careful in the hard disk in the process of assembly and disassembly, transportation, mobile hard disk bump is prohibited, the best use of foam or sponge packaging protection, to minimize the shock. 9. use plastic or rubber to eliminate hard disk noise In the hard disk speed is relatively high, if the hard disk is fixed on the metal bracket or placed at the time, once the power is turned on, the hard disk is likely to occur relatively strong shock, for a long time, it is possible to track the hard disk or scratch head. In order to eliminate the noise, we can use the hard disk near the four corners of the mounting screw holes, with a rubber band and elastic, good texture of the hard disk suspension in the case; if the hard disk is placed horizontally, we can also use the elastic and the appropriate size of the rubber mat or rubber pad on the hard disk under the column, In order to achieve the purpose of shock absorption. To note here is that we use a rubber band suspension, should choose good quality, and wrapped in silk elastic type, the best selection of clothing on the use of a rubber rib knitted fabric wrapped, so as to avoid the rubber band after failure accident. Moderately tense the rubber band and pay attention to the installation process should not hurt the rubber band
