Common notebook hard drive failure analysis
Start failure
The use of the computer process, we are likely to encounter computer can 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 tips. Due to different manufacturers or different versions of the motherboard BIOS, the message given there may be some differences, but basically pretty much the same. Here we have to use the Award BIOS is more common example of how to use the tips given to judge and deal with the hard disk can not start faults.
1.Hard disk controller failure
This is one of the
OLYMPUS li-40b battery
most common error, when this happens, they should carefully check the data cable connection to plug the existence of loose connection is correct or the hard disk parameters are correct.
2.Date error
When this occurs, the system reads the data from the hard disk can not repair the existence of the existence of errors or bad sectors 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 try to repair using specialized tools.
3.No boot sector on hard disk drive 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 the antivirus software completely killing the virus present in the system, then, with such as the KV3000 and other recovery with a boot sector of the software, try to recover 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 , Fatal Error Bad Hard Disk , DD Not Detected and HDD Control Error .
When a prompt when any of the above, usually the hard disk control circuit board, the motherboard or the hard disk interface circuit inside the mechanical parts of the body fails, this situation can only call in a specialist for the appropriate maintenance or direct replacement of the control circuit hard disk.
Failure bad sectors
Through the above study, A King on the
sony np-ft1 battery
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 their own hard disk has bad sectors that have a. A teacher that King of the introduction to the logical bad sectors and physical bad sectors and the corresponding failure of maintenance. However, before lecturing the teacher to remind A King, must be careful to do the work carefully.
Logical bad sectors
Logical bad sectors there is the daily use of 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 does not match. The main reason for this failure occurs usually because of some procedural errors in operation, or where the magnetic media sector began a harbinger of instability. Logical bad sectors in the performance of general computer use, that is, file access error or do hard disk cloning, when the reach the wrong sites, the result of an error message pop-up window and can not continue. Eliminate the logical bad sectors the method is simple, a lot of special software such as: DM, NORTON of DISK DOCTOR can do so, but the most common is Windows built-in “disk scan” function. FATl6 or FAT32 partition for it, 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 presentations, but many here also explained.
However, if using the NTFS partition and install Windows XP, this tool because it does not Scandisk, Chkdsk it can only use this tool. Chkdsk tool based on the use of file system, create and display disk status report. But if the words without any parameters, chkdsk will only display the current status of the disk drive, but will not fix any errors, to correct the error, you must include the / f parameter.
Physical bad sectors
Physical bad sectors
Dell inspiron e1505 battery
hard disk drive failure is more common. In fact, it is because the shock, scratch and other “hard” reasons, the result – some sectors of the magnetic medium Magnetic memory loss caused. Typically, such damage repair them are more trouble. Because, in the track list of the internal hard drive, this sector is marked as normal, but also the physical existence of bad sectors. Therefore, it can not scan, format, or activate the sector of low-grid method to be eliminated, it must be added to the set of this sector on the hard disk reserved area within the system to tell the disk can no longer use these tracks to the hard disk visible range of the control system to eliminate the bad sectors. Of course, this requires some special software for the average user in terms of maintenance of some difficulties.
But some of the original hard drive manufacturers will provide software tools, such as IBM / Hitachi’s DFT and the Western Digital Data LifeGuard Diagnostics. These software tools will not only scan the original speed, but also high identification accuracy, able to deal with the more common physical bad sectors hard disk failure. Therefore, the internal operation of the hard disk or the original software is more reliable, unless the original instrument can not resolve the problem, or do not recommend using third-party tools.
This relatively high compared to the above hidden way, for those users who do not ask, you can “bad disk partition device” FBDISK and Disk Genius the combination of software to complete the location of the bad sectors hidden partition made of the task. Brief description of their specific operation is as follows:
First, download the software to copy to a normal use of the computer’s root directory C, and then the hard disk is physically bad sectors hard disk attached as Part 2 on the computer. Then boot to DOS real mode, and run Disk Genius executable Diskgen, then press “Ctrl + Alt” key combination, select “hard disk” menu under “Section 2 hard.” Then you can see 2 hard disk partition specific situation. If the hard drive to re-planning, you can put all the partitions are deleted, then Save and quit.
Then run the FB Disk, select the hard disk to detect and press “Y” to begin scanning. If there is bad sectors hard disk, then the FB Disk will automatically show in which sectors and track it. After the scan is complete, it can put all the bad sectors are listed here, and ask 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 you can see through the
SD Memory Card
FB Disk after disk case, bad sectors at this time will show – kind of gray. Diskgen hidden by a little more physical bad sectors to expand some of the partition. Finally, all these bad sectors in a hidden partition, repair work will come to an end.
With the use of both applications is that, 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 Yingpan utilization is not high. Co-ordination through Diskgen to be a good solution to this problem.
