Common failure analysis of the notebook hard drive

Boot failure
In the process of the use of computers, we are likely to encounter the computer does not start. Cause system boot failure for many reasons, many of which are related with the hard disk. Under normal circumstances, when a hard disk failure, BIOS will give some English message. The motherboard of different manufacturers or different versions of the BIOS, the given message may be some differences, but basically similar. Here we use the more common of the Award BIOS, for example, to explore how to use the tips given information to determine and deal with the failure of the hard disk can not be started.
1.Hard disk controller failure (hard drive controller failure). This is one of the most common error, when this happens, should carefully check the data cable connection plug is loose, the connection is correct or the hard disk parameters are set correctly.
2.Date error (data error). When this occurs, the data read from the hard disk there is irreparable errors or bad sectors on the disk there. You can try to start the disk scanner to scan and correct sector of the logical errors, bad sectors are physical bad sectors, you need to use specialized tools to try to fix.
3.No boot sector on hard disk drive (hard disk boot sector). This may be on the hard disk boot sector is damaged, because of the hard disk boot sector is infected with a virus. Encountered in this case must be the latest version of antivirus software completely killing the virus present in the system, then, with a boot sector recovery features of the software such as KV3000, etc., try to restore the boot record. If you use a WinXP system, you can start the Recovery Console and call FIXMBR command to restore the master boot sector.
4.Reset Failed (hard reset failed), Fatal the Error Bad Hard Disk (hard disk fatal error), DD Not Detected (detected hard drive) and HDD Control Error (hard disk control error). When any prompts appear above, are generally hard to control circuit boards, hard disk interface circuit on the motherboard or the mechanical parts of the disk within a fault occurs, this situation can only professionals to overhaul the corresponding control circuit or a direct replacement hard disk.
Bad sectors failure
Through the above study, A King on the hard disk boot failure solution to understand, the next A King, of course, want to know how to deal with hard drives that have bad sectors. Teacher for A King tell us about the failures and the maintenance of the logical bad sectors and physical bad sectors. Lecturing before the teacher to remind A King must be careful to carefully do the work.
The logical bad sectors
Logical bad sectors and is prone to a daily use of the computer's hard drive failure, logical bad sectors in fact the disk tracks above the parity information (ECC) and track data and servo information does not match. The main reason for this failure is usually because of some procedural error operation, or harbinger of magnetic media sector there began to appear unstable phenomenon. Logical bad sectors in general computer use, file access error or do hard disk cloning to reach the error site, due to pop-up error message window and can not continue. Eliminate this logical bad sectors are relatively simple, a lot of special software such as: DM, Norton DISK DOCTOR can do, but the most commonly used "disk scan" feature that comes with Windows. FATl6 or FAT32 partition, you can use Scandisk in DOS real mode scan disk, system logic error sectors marked out in the future will avoid these sectors during the access operation. The use of these software is relatively simple and is also described here also, however explained.
However, if the NTFS partition and install Windows XP system, it does not have the Scandisk this tool, it can only use the Chkdsk tool. Chkdsk tool used by the file system, create and display a status report of the disk. In addition Chkdsk can also lists and corrects errors on the disk. But without any parameters, chkdsk will only display the status of the current drive disk, and not to correct any errors, to correct the error, you must include the / f switch.
Physical bad sectors
The hard disk physical bad sectors are more common hard drive failure. In fact, it is because the shocks, scratches and other "hard" because the lead - some sectors of the magnetic media has lost the ability of magnetic memory. Under normal circumstances, this damage was too much trouble to repair. Because, in the track list of the internal hard drive, this sector is marked as normal, while the bad sectors is also a physical existence. Therefore, it can not scan, format, low grid or activate the sector to be eliminated this sector must be added to the reserved area set up inside the drive, these tracks tell disk can not be used to hard disk visible within the control system to eliminate the bad sectors. Of course, this need to use some special software, repair some difficulties for the average user.
However, some hard drive manufacturers will provide the original software tools, such as the IBM / Hitachi DFT and Western Digital Data LifeGuard Diagnostics, These original tools not only fast scanning speed, and to identify the accuracy rate is also high, able to deal with the more common types of hard disk physical bad fault. Inside the drive or the original software is more reliable, unless the original tools can not solve the problem, or do not recommend using third-party tools.
Relative to the above, this advanced hidden way, for those less demanding users, the "bad disk partition FBDISK and Disk Genius a combination of software, complete the bad sectors location made the task of partition hidden. Its specific operation is briefly described as follows:
First, download the software to copy it to a normal use of the computer's C root directory, then the hard disk physical bad sectors on that computer as the two hard drives attached. Then boot to DOS real mode, and run Disk Genius executable program Diskgen, then press "CTRL + ALT key combination, select" hard disk "menu under" hard disk 2. Then you can see 2 hard partitions. If we were to re-planning the hard drive, you can put all partitions are deleted, then save and exit.
Then run the FB Disk hard drive to be detected is selected press "Y" to begin scanning. If the hard disk is bad sectors, the FB Disk will automatically show in which sectors and tracks. After the scan is complete, it can be all bad sectors are listed here, and asks if you want written to the hard disk. If press "Y" will be automatically bad sectors hidden, press the Esc key to exit.
Then run again Diskgen, then you can see the FB Disk after disk bad sectors at present - kind of gray. By Diskgen slightly hidden partition of the physical bad sectors expanded. Finally, all these bad sectors hidden in a partition, repair work will come to a close.
Both software used in conjunction with FBDisk processing hard disk may have a lot of zone, but by the software itself up to four primary partition limit will lead to a hard disk utilization is not high consequences. Diskgen with a good solution to this problem.
