Various hardware devices in the computer failure occurred in the proportion of hard drive failure is still relatively high. As the hard disk in the computer accessories play a very special place, and when it fails, ranging from the host can not be started, and at the important data may cause data loss. The specific performance of hard disk failures are diverse, in this paper to explain in two aspects mainly the fault, Part I will introduce to the hard disk boot failure can not be resolved. Next was the logical and physical bad sectors you about treatment.
Start failure
In the use of computers, we are likely to encounter computer does not boot. Cause system boot failure for many reasons, many of which are related with the hard disk. Under normal circumstances, the time when the hard disk failure, BIOS will give some English message. As different manufacturers or different versions of the motherboard BIOS, the information may be given prompt some differences, but basically much the same. Here we have to use the more common Award BIOS, for example, explore how to use the tips given information, determine and address the hard disk could not be activated faults.
1.Hard disk controller failure (hard disk controller failure). This is one of the most common error, when this happens, they should carefully check the cable connection to plug the existence of loose connection or a hard disk is correct parameter setting is correct.
2.Date error (data error). When this occurs, the system reads the data from the hard disk can not repair the existence of errors or bad sectors exist on the disk. At this point you can try to start the disk scanner, scan and correct the logic of sector errors, if there is bad sector physical bad sectors, you need to use specialized tools to try to repair.
3.No boot sector on hard disk drive (hard disk, no boot sector). This may be the hard disk boot sector is damaged, generally because of the hard disk boot area has been infected with the virus. In such cases you must use the latest version of antivirus software and complete killing of virus present in the system, then, with such KV3000 other with boot sector recovery software, attempt to recover the boot record. If you use WinXP system can start the "Recovery Console" and call FIXMBR command to restore the master boot sector.
4.Reset Failed (hard reset failed), Fatal Error Bad Hard Disk (hard disk fatal error), DD Not Detected (not detected hard drive) and HDD Control Error (drive control error). When a prompt appears when any of the above, generally the hard disk control circuit board, the motherboard is the disk drive interface circuit or the interior of the mechanical parts of a fault, this situation can only be requested for the corresponding control professional maintenance or direct replacement of the circuit hard disk.
Bad Track Fault
Through the above study, A King on the hard disk boot failure can not understand the solution, and then A is of course the King would like to know how to deal with bad sectors it has its own hard drive. This teacher of King on the brief for the A logical bad sectors and physical bad sectors of the fault and the corresponding maintenance. However, before lecturing, the teacher reminded the Arab King, must be careful to do this work carefully.
Logical bad sectors
Logical bad sectors there is the daily use in the computer vulnerable to a hard disk failure, the logical bad sectors the disk track is actually verify the above information (ECC) and servo-track data and information do not match. The main reason of this failure often occurs because of some procedural errors in operation, or where the magnetic media sector began a precursor to instability. Logical bad sectors in the performance of general computer use, that is, file access error, or do hard disk cloning, when the parts reach the error, the result of an error message pop-up windows can not continue.
Eliminate the bad sectors of the method is simple logic, many proprietary software such as: DM, NORTON of DISK DOCTOR can do so, but the most common is Windows built-in "disk scan" function. For FATl6 or FAT32 partition, this can be used in real mode DOS Scandisk scan disk, then the system can mark out the logical error of the sector, after carrying out access operation will avoid these sectors. Because the software is simpler to use and also many have introduced here also, but more explained.
However, if using the NTFS partition and install Windows XP system, because it did not Scandisk this tool, it can only use this tool Chkdsk. Chkdsk tool based on the use of file system disk to create and display a status report. Chkdsk also lists and also to correct the disk errors. But if the words without any parameters, chkdsk will only display the current status of the disk drive, and will not fix any errors, to correct an error, you must include the / f parameter.
Physical bad sectors
Physical bad sectors hard disk drive failure is more common. In fact, it is because the shock, scratches and other "hard" reasons, the result - some sectors of the magnetic medium Magnetic memory loss caused. Typically, this is too much trouble all up to repair the damage. Because the hard disk inside track list, this sector is marked as normal, but also the physical existence of bad sectors. Therefore, it can not scan, format, or the activation of low cell sector method to be eliminated, must be the sector to set up a system within the hard disk reserves, to tell the disk has not used these tracks to the hard drive visible within the control system to eliminate the bad sectors. Of course, do need to use some special software, the maintenance of some difficulties in terms of ordinary users.
But some hard drive manufacturers will provide the original software tool, such as IBM / Hitachi's DFT and Western Digital's Data LifeGuard Diagnostics. The original factory scan tools will not only speed, but also high identification accuracy, able to deal with the more common physical bad sectors hard disk failure. Therefore, the hard drive or operate within the original software more reliable, unless the original instrument to solve the problem, or do not recommend using third-party software tool.
This relatively high compared to the above hidden way, for those less demanding users, you can use the "bad disk partition device" FBDISK (http://www.mydown.com/soft/78/78897.html) and Disk Genius (http://www.mydown.com/soft/53/53403.html) the combination of software, the completion of the location of the bad sectors hidden partition made of the task. Brief description of their specific operation is as follows:
First, the software will download to copy to a normal use of the computer under the root directory of C, then there physical bad sectors hard disk drive as the first two hooks on the computer. Then boot to DOS real mode, and run Disk Genius executable Diskgen, then press "Ctrl + Alt" key combination, select the "hard" menu under "No. 2 hard." Then you can see 2 hard disk partition specific circumstances of the. If this piece of hard to re-planning, you can delete all the partitions are, and then save the file out.
Then run the FB Disk, select the hard disk to detect and press "Y" to start scanning. If there is bad sectors hard disk, then the FB Disk it will automatically show in which sectors and tracks. After the scan is complete it could have listed out all the bad sectors, and asked whether you want to write to the hard disk. If you press "Y" will automatically hide bad sectors, press the Esc key to exit.
Then run again Diskgen, then we can see through the FB Disk disk treated the case when the bad sectors will approach - kind of gray. By Diskgen again will hide the physical bad sectors slightly expand the number of partitions. Finally, all these bad sectors on a hidden partition, repair work ends.
Both the software used in conjunction because, after FBDisk treatment may have a lot of hard disk partition, but by the software itself up to 4 primary partition limit will lead to the consequences of low utilization drives. Coordination through Diskgen, it can solve the problem.
