1. hard disk failure of the three responses
You sit comfortably in your favorite computer chair, and snapped open the display switch, then press the power switch. Greet you is the computer Kaga reassuring voice, and rotation of the cooling fan whirr. You a little later lying to the back of a chair and absently started looking at your old friend.
You think that you had, hundreds of problems are come to mind, why start the computer these days are so slow speed. And then the unfortunate happened. Hard endless sharp turning, and finally into a huge and disturbing noise. flash of the screen is \Do not be afraid. There are simple steps we style guide can help you recover all hard disk failure, plus the secret to the prevention of problems in advance. In your search for a screwdriver before try this.
Step 1: to soft
When your computer hard drive fails, the first thing to do is check the computer’s BIOS (Basic Input / Output System) settings. If the number of your hard disk capacity is not correct, the whole system may break the link. You may just need change some settings, will be able to solve the problem.
Check the BIOS settings
Press the computer BIOS configuration options can be exhaled buttons – usually F2 or DEL. According to the different BIOS manufacturers, you may see a further list of options, or directly into the place you want, but also namely: the standard BIOS options screen.
In the standard BIOS options screen, find the hard disk or IDE device options. Take a look at your hands hard drive specification table, and then check the BIOS in the SIZE or MB and so on, and then look at one number – the two should be very close, if BIOS settings and the actual installation of the computer’s hard drive size is inconsistent, then change some of MB. These settings must be correctly installed on the computer correspond to the actual specifications of the hard disk. or BIOS will think that the hard disk is broken.
If the number is not correct. Or where the number appears, it shows \hard choices (Auto). Select the item, then BIOS will check the hard disk, read the hard drive setup data, then automatically populate the data space.
If this does not work … … if you try the automatic identification (or your BIOS automatically try to), but the BIOS can not recognize the hard disk, then the problem is rather serious. This is a turn off on the computer, aside from the plug, open computer case time. roll up your sleeves to make a few basic hardware checks it.
Step 2: to hard
Before you open your system should let their contact with the computer’s metal frame to release static electricity to prevent damage system components. And then allocated to the computer’s power cord. (Note: If you open the computer and later at the station up and walk around, you have to plug then plug it back in, re-ground, and then plug pulled out to ensure that your body is not static.)
Check the hard disk connector
The computer’s shell apart, and then check the connection with flashlights on the hard disk connector. Hard disk itself has two connectors: Connect the hard drive and four-wire cable between the power supply connector, and connect the hard drive data cable connector to the motherboard. If the connector loose, and the still harder on – be careful not to bend the foot. The two cable joints are usually designed to only insert a single direction, so it should not be inserted wrong.
Also check the slender yet linked to a hard drive cable end, to ensure that it connected to the motherboard. If you find a loose connector, will it plug it back. If it’s interface is not as loose joints, and will it plug it back. If it’s interface is not designed specifically for the joints too, you have to carefully examine whether the board, printed with a small \Pushing their
Long electrical expansion and contraction, will lead to the connector pins loose contact with each other, just look at is undetectable. So when you open the shell, you can gently shake the hard disk and each connection on the motherboard connector – better way is to poke each connector not return again to restore the contact state. In addition, the bumper of your cable data cable for this test. If it becomes very hard, try for a new article – - There may be a package attached to an article of insulation inside the cable broke. but make sure you change the same type of cable. Once you have done these things, and plug the power plug it back in, start the computer, and then see what happens.
Step 3: Ultimate Countermeasures
You use the flashlight up and down according to all over the computer inside. You get to explore all the cable lines, re-insertion of joint, even looking from another wire. Hard but still did not move.
Call customer support department, which is to surrender and call customer support time. First try to ask your computer vendor, or the hard drive manufacturer’s technical staff. Maybe they will come across the same problem before, even talked about the way we have other than simple solution.
However, if finally found the sad fact is that your hard drive has been under a hell, please double-check after next – even if your computer has been a shelf-life, hard drive might still within the guarantee period. Although most computer vendors, the time machine in the sale offer one to three years shelf-life, hard drive manufacturers are usually two to five years to provide a guarantee. and their shelf life is usually not only on the original purchase cost of mailing the hard disk , should be able to change to a new hard drive.
To maintain the health of your hard disk
Finally, is to keep a healthy hard drive. Often similar to the ScanDisk tool and so the hard disk scan to check bad blocks, this tool has a Windows 95/98 Annex to the inside. It can help you avoid potential problems, or the problem becomes serious before, took them to get rid of.
2. Hard disk interface needle cause a malfunction
Breakdown phenomenon: I few days ago the system (WinXP) does not suddenly start up (my PC configuration: MSI KT333 +8233 A, West Czech Barracuda IV 60G), the phenomenon is stuck in the splash screen and can not enter the operating system. Start I did not take too much notice, that might be a problem with the startup files, repair what has become. But do not try a few times into.
Analysis solution: I think the virus might be trouble, trouble still after the virus. Reinstallation and start very slowly, and the hard disk light flash crazy. Into the system a bit after I test the hard drive transfer rate, found that second only 4MB! I think the issue of transfer mode, open Device Manager, and really hard work in PIO mode, strange, I am a hard working manual adjustment mode, reboot the system and found the mode Surprisingly, the hard disk PIO mode!
Basic problem here has been to find, hard to lose the support DMA mode. I go to the official website WestJet special tool to change the hard disk mode, but detect the hard disk at this time of the default mode is DMA, then use the West Czech disk error checking tool dedicated a full inspection. Everything was fine! I began to feel failure may be caused by hardware. carefully Attorney finally found the problem after a hard drive, IDE hard disk interface to actually broke a needle. I rushed with plum port The screwdriver unscrew the screw, outside the West Czech hard metal protection plate and sponge removed, exposing the circuit board, from other places to find a jumper pin, little pin up to the original place and weld. and then the hard disk recovery After reloading system troubleshooting.
3. Notebook hard drive failure analysis common
Start Fault
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. In general, when the hard drive fails, when, BIOS will Some tips are given information in English. motherboard due to different manufacturers or different versions of the 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 to determine and address the hard way not start trouble.
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 data cable connection to plug the existence of the loose connection is correct or hard drive parameter settings are 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 sector logic error, 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 (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 must be first with the latest version of the antivirus software completely killing the virus present in the system, then, with such KV3000 boot sector recovery with such software, try to recover the boot record. If you use WinXP system can start the \\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, the general are hard control 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 circuit professional maintenance or direct replacement of the hard disk.
Bad sectors 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. Teacher this issue brief on the logic for the A King Bad sectors and bad sectors of the fault and the corresponding physical maintenance. but to lecture before the teachers to remind A 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. There such a failure main reasons are usually 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 logical bad sectors of the method is simple, a lot of proprietary software such as: DM, NORTON of DISK DOCTOR can do so, but the most commonly used or the Windows built-in \operations will stay out of these sectors. Because use of these software more simple and also many have introduced here also, but more explained.
However, if the use of the NTFS partition and install Windows XP system, because it did not Scandisk this tool, it can only use the Chkdsk this tool. Chkdsk tool used for file-based systems, create and display disk status report. Another Chkdsk also to set out and correct errors on the disk. but if it does not take 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 of shock, scratches and other \fix up all the damage is too much trouble. because the track list in the internal hard drive, this sector is marked as normal, but also the physical existence of bad sectors. Therefore, it can not scan, format, low-grid or activation sector approach 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 disk control system can be seen in the context of eliminating the bad sectors. Of course, do need to use some special software, in terms of maintenance on some of the difficulties 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 software tool not only scan speed, and identification accuracy is also high, to deal with the more common Physical bad sectors hard disk failure. Therefore, the internal hard disk or the original software to operate more reliable, unless the original instrument to solve the problem, or not recommended to use third-party tools.
