Solutions to common computer hard disk failures
Error in hard disk detection at startup
Hard disk detection at startup sometimes fails and appears:? primary masterharddiskfail? ; After the detection fails, sometimes it can be reset in BIOS with AUTO DETECT, and sometimes AUTODETECT can't find the hard disk.
please check in the following order: check whether the hard disk cable is loose; Try a good hard disk cable. ; Try changing the hard disk to another machine and changing a motherboard-make sure the IDE port is ok; It may also be a problem caused by power supply, so change to a better quality power supply; Carefully check the PCB of the hard disk. If there are burnt marks on the PCB, please send it for repair as soon as possible.
in short, once it appears during the self-inspection? HARD DISK FAILURE? Prompt, please use the replacement method quickly to determine whether the hard disk is faulty. If a physical failure of the hard disk is suspected, it needs to be repaired or replaced.
BIOS setup and installation problems
If the hard disk parameters in the BIOS are set incorrectly, the self-test will not pass, and the hard disk cannot be used normally. First, check the setting of hard disk parameters in the BIOS. Generally speaking, computers after 486 will have the function of automatically detecting the hard disk model. After entering the BIOS and finding the IDE HDD AUTO DETECTION item, the hard disk model will be automatically detected.
if your hard disk is larger than 528MB, please note that when setting it in the BIOS, set its mode to? LBA? In computers after Pentium, what is the default hard disk mode? LBA? . If it is set to other modes, errors will occur when reading and writing the hard disk, and even the hard disk data will be lost. Common failures during installation may be due to poor contact of IDE cable or the cable interface is connected backwards. If the signal computer is connected backwards, you will find that the hard disk indicator light on the chassis is always on.
judging the hard disk failure by sound
if the hard disk is not detected. The first thing to consider is the hard disk. As long as the hard disk is powered on, it will keep running, and the speed is more than 5, revolutions per minute. These mechanical structures will inevitably fail. When you can detect the hard disk in CMOS, listen to the sound from the hard disk. If the sound is:? What? What? Then calm is restored, and there is a greater certainty that there is probably no problem with the hard disk; What if the sound is? What? What? Da, and then how many times in a row? Click? Click? If it sounds, there is a great possibility that there is something wrong with the hard disk.
the worst case is that the hard disk appears during the self-test? Da, da, da? Periodic noise like this indicates that there is something wrong with the mechanical control part or transmission arm of the hard disk, or the disk is seriously damaged. How normal is the hard disk temperature? For further judgment, you can remove the hard disk, connect it to another computer, and then check it in CMOS. If it is not detected, it can be concluded that it is really a hard disk problem.
Hard disk error after overclocking
Appears after overclocking? Hard disk read and write failed? This is probably the problem with the hard disk. Many hard disks will have some problems when working at high external frequency, ranging from being unable to start, to losing data. You can try to reduce it to MODE 3 and shorten the length of hard disk cable as much as possible. 1M adopts asynchronous bus, which is three-frequency division (33M) for PCI, so there is no special requirement for hard disk. For non-asynchronous buses, the limit external frequency is about 92M (that is, the PCI speed is 46M), which is unbearable for almost all hard disks.
Of course, if you really can't solve or encounter other computer problems, you can leave me a message, or visit 1B2 Computer Hospital on the first floor of Bainaohui, Shiqiaopu, where professional engineers will serve you. One advantage of coming to the first floor is that you can pack the goddess together, so you will have a chance to travel together, which is also a world of two people. When the computer problem is solved, let's make an appointment with the goddess to have a romantic lunch | dinner at the food court on the fifth floor of Bainaohui. Isn't it a step closer to the goddess!
