Hard disk failure repair techniques-1

As a storage device in a hard drive plays an extremely important role. However, due to the hard disk are magnetic media, so its life expectancy and stability of the memory and other devices not as good as when using all kinds of problems would inevitably arise. And make the situation more complex, due to the hard disk to the system involves setting the bottom, they are often not familiar Windows, resolve the problem, go to DOS must be dealt with under the terms of that for a lot of DIY novice a bit at a loss, and after all they have not experienced the DOS era.

Hard drive problems before the general symptoms of

If the hard disk fails, then the best early detection and timely take corrective measures. If you wait until the terminally ill, the hard disk of your valuable data is difficult to escape the. In general, the hard disk fails, there will be the following performance:
1. S.M.A.R.T failures prompt appears. This is a hard drive built-in hard drive manufacturers themselves inside the auto-detection feature is at work, there are prompted to describe your hard drive that have the potential physical failures, and soon there will not be running from time to time in the case.
2. In the Windows initialization crash. This situation is more complex problems should first rule out the possibility of other components, such as memory, poor quality, fan stall cause system overheating or damage caused by viruses and so on, finally if it is determined if the hard disk failure, and then dealt with separately.





3. Be able to enter the Windows system, run the program, but an error can not run disk scans, often slow and stagnant or even crash when scanning. This phenomenon may be hard drive problem, it may be Windows constant, daily soft fault, if the software is set to exclude the possibility of problems, you can certainly have the physical failure of the hard disk.
4. To enter Windows, run the ScanDisk found an error or even bad sectors directly, which does not need me to say, Windows will be a detailed inspection procedures for reporting.
5. In the BIOS suddenly could not distinguish between the hard disk, or even to identify, but also the operating system can not find the hard disk, which is the most serious failures.

Unfortunately, the great fortune - the destruction of the partition table

First, we should recognize the hard drive power interface and data lines do not fall off, and then enter the BIOS, use the "HDD Auto Detect" to detect the hard disk. If the BIOS can correctly identify the hard drive at this time, then at least your hard drive there is hope of treatment; Otherwise, I think we have no fuss, because I think our average DIYer tool at hand is essentially powerless.

CD-ROM or floppy disk boot system, you can try to enter the C drive letter, if you are prompted at this time can not find the C drive, then definitely be a good thing. This occurs is likely to be the hard disk partition table information has been destroyed, or are some kind of virus attack. If the hard disk for your data does not matter, you can first use FDISK / MBR command to unconditionally remove the contents of the partition table, and then use FDISK and other partitioning software to re-format the partition, generally this way we can solve the problem; and if you still need the hard disk the data, then the steps to take some work. The best time to have a kill-virus software or a motherboard with a gift related software, and then you can refer to the help documentation, generally the software will contain the command to restore the hard disk partition table, but also extremely easy to use.

For there is no antivirus disk users, we can use the NU 8.0 in the NDD repair, it will check the partition table errors. If it is found wrong, NDD will be asked if you are willing to modify, as long as you continue to answer YES you can correct errors, or the partition table with the backup off-line coverage of it.

Can be achieved with the Hide Partition

If the above method does not solve the case, can also use FDISK to re-partition, but the partition size must be the same as the original partition, which is especially important not to carry out high-level format, after partition, but use NDD to repair it. This will not only ensure that the hard disk can be repaired after the start, but the data on the hard disk will not be lost.
