External hard drive as the computer's memory capacity bigger and bigger, but the stability seems to have become more and more as before. Now there are three, 400 MB of IDE interface to the old hard drive in the secondary market sales, and not be any problem with them, just too slow. New large capacity hard disk can do? Speed is much faster, is Santianliangtou's something wrong.
Hard drive during use, due to the quality of the hard disk, power supply bad, virus damage, high-frequency interference, etc. The fault phenomena occur as follows:
1. Hard occasional loss of data
According to theory, under normal circumstances should not be lost hard disk data. But because the hard work in high speed, around the time of electromagnetic interference may cause the hard disk read and write data in the error occurred. Although there may be 1 or 0 written to be read into a 0, but we encountered the user is operating the computer can not find the file or files are damaged can not normally open, that is, data is lost. This is why we have perfectly good computer, restart the system after the reasons for not entering, reloading the system to resolve problems.
However, the most important to note that: With the rapid development of the network, the virus began to spread, but also to make our computers become more and more insecure. Some viruses specifically for destruction of certain files, so if some file is missing or not open, the best to check narcotics, to determine whether their computer is infected with a virus, to prevent because the virus caused the losses. If a One morning, when we turn on the computer and found that some file is missing, it is best not to make a fuss, the first complete anti-virus on the computer, while antivirus software on the computer upgrade time.
2. The hard disk has bad sectors continue to appear
There are two reasons for this situation, one hard drive poor quality, control chip timing error, resulting in a large area of bad sectors occurred; second hard drive is not the normal power supply, power supply voltage is low, resulting in positioning not allowed to read the disk when the surface over an extensive area of bad sectors. The quality problems caused by bad sectors hard drive, better warranty if you can find business for a new one. But if 过了保修期 then on nothing with, and can only buy new.
3. Sometimes hard to find in the BIOS, sometimes not found
Cause of this failure may be caused by:
1) The board's IDE controllers have problems;
2) hard disk interface circuit fault or a hard disk magnetic head arms control circuit or a problem, can not properly read the data;
3) hard drive power supply voltage instability, when the normal power supply be able to find the hard disk, hard disk is lost when power is low;
4) host overclocking, causing the hard drive clock frequency is too high, and instability;
5) there is the hard drive cable and hard drive interfaces and hard drive power connector problem, caused by poor contact.
Time being considered here, the hard drive jumper error, the main conflict situations from the disk set.
4. Hard to find in the BIOS, but not the normal format and the use of
This communication is usually part of the interface hard disk no problem, but the hard drive read and write control part and data part of a problem. If the hard disk read and write did not sound abnormal, but can not be formatted, even when low lattice constant error, this is generally hard to read and write parts of a problem with the circuit, read and write data, the error rate is too high To.
5. Hard to realize that in the BIOS, but can not boot the system
This situation also has a variety of reasons:
1) hard disk 0 track error, can not properly read the disk partition information;
2) hard drive partition information is damaged or man-caused increases in the logic lock;
3) hard to read and write control circuit and circuit errors cause data read and write error;
6. Hard copies of the data particularly slow
There are reasons for this are several:
1) hard drive using the wrong data lines, such as support DMA100 DMA33 hard drive using the data lines, resulting in decreased hard drive data transfer;
2) hard drive data cable connected the wrong direction, DMA66, 100 and 133 hard drive data cable is directional, if reversed, and also be able to read and write properly, but the speed decreased, and sometimes slow intolerable;
3) hard disk DMA channel is turned off, not using DMA data transfer mode, and block transfer of data using traditional methods, resulting in a substantial reduction in data transmission;
4) hard to read and write data circuit or interface circuit, is also possible that the IDE interface circuit board problems, resulting in lower data transmission rate;
5) There is also insufficient power supply hard drive or power supply ripple in the system is too large, it is mainly lack of host switching power supply or power after the filter capacitor used for a long time due to loss of content or leakage.
7. Abnormal sound when the hard disk can read the disks
Usually happens is the magnetic hard disk arm or head damage caused by a hardware, such as magnetic arm broken, head off or deformation after dislocation, and the hard drive disk exposed to the sound of screaming exception. This happens most of all that hard drive has come to an end. If you have important data on your hard disk, looking for the best in a very professional data recovery company, to use special equipment to read out the data, generally do not expect to have repaired the hard disk may be.
8. The hard disk in use for some time, turn "rattle rattle" sound straight
Some of this is a boot disk appeared this "rattle rattle" sounds like ringing against the wall, some hard drives using a time lag. This "rattle rattle" sound is the magnetic hard drive arm in moving Dongzuoguotai, outliers, resulting in collision with the case issued in abnormal sound. Generally speaking, this situation can only be scrapped hard drive, not worth repairing.
9. The operating system prompts the realization that the mobile hard disk, hard disk, but can not correctly install the driver, can not be used
This phenomenon is due to move the hard drive power consumption, +5 V 700MA need more current, the general board of the USB interfaces to provide the current only 500MA, supply current is insufficient hard disk drive motor work properly, causing no mobile hard disk drive is properly installed. Mobile hard drive will also hear a continuous "buzzing" and to sound, not the normal hard disk to time "creak" sound.
To the above circumstances is often hard disk failure, we found that in the course of his hard drive if there is such a case, if during the warranty period, you should as soon as possible to back up your data, then sent to distributors hard drive Department for replacement, because usually the dealer is not responsible for data backup.
With hard disk capacity and speed of rapid increase, hard drive data appears to be growing up without the insurance. In 2078 before the 12 megahertz of the small hard drive, although a little slow, but could still use. Now the hard disk can not be allowed, and some hard just bought home a week, they begin to lose the data, and sometimes the entire hard drive partition gone, you will not blame blame. The most certain way, or buy a burner, ready to write your own articles or download the data, write the program code carved disc, it can not lose friends.
