Hard to judge and rule out common faults

1, detect the hard disk boot error

Sometimes detect the hard disk boot failure, appears: "primary Masterharddiskfail". Sometimes can be detected through the normal start. Sometimes after a failed test can be used in the BIOS, reset the AUTO DETECT, sometimes AUTODETECT can not find the hard disk. Please check the following order: Check hard drive cable is loose; for a good hard line try. Change the hard drive to another machine to try, for a motherboard - Confirmation IDE port no problem. Also possible that the power lead to problems for some of the power of a good quality. Carefully check the hard disk of the PCB, PCB board if there are signs of burn out as soon as possible repair.

If the motherboard detects the hard disk, then please confirm that the detected hard disk capacity and DM74S138N datasheet and other parameters and DM74S138N price and the actual hard disk parameters are the same. If the detected hard disk capacity and DM74S138N suppliers and the actual difference, indicating that the system will malfunction, and this situation may occur for hard drives, motherboards, and even hard disk data lines. Can be confirmed by substitution.

Short self-test once when "HARD DISK FAILURE" like the tips, please use the rapid replacement method to determine whether the hard disk failure. If you suspect a physical hard drive failure, you need to repair or replace the hard disk.

2, BIOS setup and installation problems

BIOS, hard drive parameters if not, will not pass self-test, hard disk is not properly used. First check the hard disk parameters in BIOS settings, in general, there will be 486 after the computer automatically detect the drive model features into the BIOS, find the IDE HDD AUTO DETECTION one, it will automatically detect the hard disk models.

If your hard disk larger than 528MB, please note that in the settings in the BIOS, its mode to "LBA", later in the Pentium computer, the default hard mode is "LBA". If set to other mode, read-write hard disk errors, and even lead to the hard disk data loss. Common failures during installation, possibly because of bad IDE cable or the cable interface may also be reversed out. If the signal is reversed computer, you will find the chassis length on the hard disk light is on.

3, fault-tolerant disk prompt Referring now to the hard disk before

have taken a number of fault-tolerant technology, which is the most common SMART technology. If the screen displays "SMART Failure Predicted on Primary Master: ST310210A" then the warning: "Immediately back-up your date and replase your hard disk drive. A failure mauy be immnent." At this point, subject to F1 to continue, which is SMART diagnostic testing technology to your hard drive may be failing or unstable situation, warning you need to back up your data immediately and replace the hard disk. This prompt appears, in addition to the new disc replacement, but no other solution.

4, by the sound of that hard disk failure

If not detected hard drive. First to consider is the hard drive, and drive as long as a power to stop the operation in the, and every minute is more than five thousand transfer speed, the mechanical structure inevitably fail. Can be detected in the CMOS when the hard disk, listen to the sound of the hard disk, if the sound is: "da ... da ... da ... ..." and then return to calm, there is sure to judge the larger hard drive is probably not a problem; If the sound is "Da ... da ... da ... ...", issued several times in a row and then "clicks ... clicks" of sound, then there may be very hard a problem. The worst situation is when the hard disk self test "up, up, up" like the periodic noise, it indicates that the mechanical control part or the hard disk drive arm problems, or serious injury of the disc. In order to determine, you can remove the hard disk, the computer connected to the other, and go to CMOS to detect that, if is not detected, then it can be concluded, really hard problem.

5, overclocking the hard disk error

After overclocking "hard disk write failure", it is likely that the hard disk problems. A lot of hard work in high FSB will have some problems, ranging from not start, while in data loss, you can try it down to MODE 3, and to shorten the length of the hard disk cable. The use of asynchronous bus 100M, that is one-third of PCI frequency (33M), so the hard drive and no special requirements. For non-asynchronous bus, the FSB limit is about 92M (speed of the PCI 46M), Under these conditions, almost all of the hard disk can not afford.

6, the drive circuit board or chip burning Once the power reverse drive

other reasons, it will cause damage (BIOS is not recognized), hard drive circuit board burned sure, this generally does not hurt the plate body, if I could find the same type of circuit board replacement (If you are lucky just replace a circuit board components), the possibility of repairing the hard disk should be above 80%, the data are still generally restored. If you can not repair disk data also really valuable, you can find professionals to the hard drive apart, remove the disc, as long as the plate body without injury, most of the data will be used specifically to read the disk drive read out. Hard drive circuit board burned, computer accessories are "non-normal damage", for whatever reason are not covered by the warranty, just nothing with.

7, power management settings problem

Sometimes the computer will appear, the hard disk of my hard drive suddenly stops and sometimes for no reason "toot" sound stopped and then immediately start, you can clearly hear the voice of hard-starting motor. If nothing else wrong with the hard disk, it should be the BIOS settings, please check the BIOS settings, "power management" in the "HDD PowerDown" items, to Disable away.

Power Manager Setup in the BIOS, the options have to turn things into CMOS Power Management Setup found in the Power Management is set to MAX Saving (hard disk in 1 minute, such as numerous power to stop into the Power Down state), This means that sometimes when reading or writing the command transfer, sometimes the hard disk is in a stopped state, need to "start" to enter the work state, so when the slow hard disk performance is too fast.

8, hard disk bad sectors to determine

First, we should distinguish between the logical bad sectors or a physical bad sectors. Format through the format simply remove the bad sectors is a high-level logical bad sectors and can not get rid of is the physical bad sectors. Logical bad sectors on the hard drive has little effect, while the physical bad sectors is a "contagious", once said that physical bad sectors on your hard disk drives have serious quality problems or life is coming, should be quickly replaced.

Logical hard disk failures can be divided into two types of damage and physical damage. If it is logical damage, big deal FORMAT, reinstall the software. With the physical damage is bad sectors, if the situation is not particularly serious, to take appropriate measures, generally solve the problem. What are the phenomena that drive has physical damage it?

Read a file or run a program, read the disk and hard disk error again, or go through a very long time to be successful, while the hard disk will be issued a strange noise, a phenomenon that the hard disk has bad sectors. Startup disk can not boot the system, with the SYS command to transfer the system can not succeed. This is most likely the hard disk boot sector is a problem. FORMAT hard disk, to a schedule at a standstill, the last error, can not be completed. FDISK the hard disk when the schedule will be repeated to a retreat into advance and retreat. The easiest way to start. If you can enter the Windows 9X systems, in the "My Computer" right-click the hard disk drive, the shortcut menu select "Properties" in the "Tools" page select the box for a full scan on the hard disk, and on the possible bad clusters for automatic correction. Windows 9X in large part because the auto repair logical bad sectors only, and can not automatically repair physical bad sectors, so, another large hard drive distributor, generally have a special test whether there are physical bad sectors hard disk special equipment.

9, will be designated as bad sectors of a partition Once the bad sectors

fact, the usual approach is often ineffective. So, we can make marks on these bad sectors, bad sectors not to use these, remember the location of bad sectors, then the hard drive FORMAT, the area will have bad sectors into a single designated area, do not later on in this area access the file. If bad sectors are not continuous, but are far apart, bad sectors can be drawn in a nearby area, more than a few designated areas. Around bad sectors should be left appropriate "good road" space as a buffer, because a proliferation of bad sectors, if the use of over-relying on the past with bad sectors "good road", then before long, the hard disk in turn the emergence of new bad sectors. PartitionMagic deal with the hard drive is also very convenient, PartitionMagic can not destroy data in the case of re-partition the hard drive, dynamic change partition size, change the partition file format, hide or show the existing partition and so on. PartitionMagics DOS version of the copy on a floppy disk, boot the system with WIN9X boot disk, run the floppy disk PQMAGIC.EXE. Scan the hard disk can be directly used PartitionMagic in the Operations menu "check" command to complete, marks bad clusters, you can try to re-test it, is in the Operations menu, select "Advanced / bad Sector Retest"; the bad clusters into one (or several) zone, then through the Hide Partition menu item to hide the partition with bad sectors to avoid Windows9X misuse. To note that, if not directly formatted partition will hide bad sectors, then the subsequent partition of the partition drive letter will change as a result of some of the procedures and the letter can not be run correctly. The solution is to use Tools menu DriveMapper menu item, it will automatically collect the shortcuts, and registry information in the application immediately update the drive letter parameters to ensure the normal operation of the program.

10, damage on track processing Zero track

corrupted hard disk, you can try PartitionMagoc (hereinafter referred to as PM). A plate from the start, run PM, in the main interface to the mouse to identify a need to manipulate the partition (ie C drive), the first partition on the main interface of the upper part of the chart to select the partition, and then right-click on this icon and Select "Adjust volume / mobile" will then see a window, drag the volume slider left top of the window, then the lower part of the free space will make the appropriate changes. Such as the capacity to adjust to a suitable, press "OK" button, you can drive in a little more free space. Corrupted the free space contains zero track included, we will hide him. Can make the disk back to life.

Damage to the hard disk sector 0, although tricky, but not hopeless. Basic idea is to try to mask the damaged sector 0, but with a sector instead. The ideal software to complete this work is Pctools9.0 the DE tools, specific methods are as follows:

Hard damage on track are more common, but also more serious hard disk hardware failure, disk 0 track damage in most cases only scrapped. But if you think the 0 replaced by 1, there is resurrection possible. You can use the DISKEDIT Pctools9.0 tools, or old versions of the DM. However, not much chance of success. Most of the time could not fix. Try using PCTOOLS 9.0 in DE. Open the Select menu Run DE, then there will be Partition Table, select and enter, followed the partition table information. L is the C drive partition, the partition is started from the hard disk cylinder 0, then, will be a partition of the Beginning Cylinder of 0 to 1 on it. Save and exit. Restart, press the Delete key to enter the settings back to COMS, the "IDE AUTO DETECT", save and exit, re-partition, format that may be repaired.

11, on the hard disk low grid

On the hard drive for low grid. Less than a dead end, this move is best not to use. Because of the harmful effects of hard for a lot of low grid, at least speed up the wear and tear on the disc, and, on the hard disk has bad sectors, the low grid will accelerate the spread of bad sectors. However, true to this point, only "dead horse a living horse rule" the. However, the success rate of this method is not high, the hard disk has bad sectors, sometimes low grid can not be passed, I encountered a hard, low grid several times barely passed, the results still can not FDISK, but to repair .

Hard disk bad sectors, the general need to do low-level formatted. The so-called "low grid", it simply is to hard disk as a "bare drive" and sector re-classified track, mark the address information and set operations such as cross-factor, if it is logical bad, "low grid" could be restored after the general . If it is physical bad sectors, it may be blocked. "Low grid" of the process is very slow, power-down occurs if the half-way crash and other unforeseen circumstances, will cause very serious consequences, and because of "low grid" when the physical properties of low-level hard disk to make changes in the life of the hard disk will definitely be effective, it is generally easy to do on the hard drive "low grid" operations. (I personally think that no matter what is clear, "vicious" * really do not need jail, "low grid" big head, most re-zoning, high cell on the line. Of course, another matter when there is bad sectors, "dead horse a living horse" doctors. ) but in any case, once the bad sectors hard disk, indicating the reliability of its existing problems, or quickly replace the best way to avoid greater losses.
