Detecting the hard disk sometimes fails during startup, and the message "primary masterharddiskfail" appears. Check if the hard disk cable is loose; try another good hard disk cable. Try changing the hard disk to another machine, and change the motherboard to confirm that the IDE port is okay. There may also be problems caused by the power supply. Use a better quality power supply. Carefully check the PCB of the hard disk. If the PCB board has burnt marks, please send it for repair as soon as possible.

If the motherboard detects a hard disk, first check whether the detected hard disk capacity and other parameters are the same as the actual hard disk parameters. If the detected hard disk capacity is different from the actual one, it means that the system must have failed. This situation may be caused by the hard disk, the motherboard, or even the hard disk data cable. Can be confirmed by replacement method.

If the hard disk parameters in the BIOS are set incorrectly, the self-test will not pass and the hard disk will not function properly. First check the settings of the hard disk parameters in the BIOS. Generally, 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, the default hard disk mode is "LBA". If it is set to other modes, errors will occur when reading and writing the hard disk, and even data on the hard disk will be lost. Common faults during installation may be due to poor contact of the IDE cable or the cable interface is reversed. If the signal computer is reversed, you will find that the hard disk indicator on the case is on.

As mentioned earlier, hard disks have adopted a number of fault-tolerant technologies. Among them, the most common application is S.M.A.R.T technology. If the screen displays "SMART Failure Predicted on Primary Master: ST310210A" and then the warning: "Immediately back-up your date and replase your hard disk drive. A failure mauy be immnent." At this time, you must press F1 to continue, this is SMART A technical diagnosis has detected that your hard disk may be malfunctioning or unstable, and warns you that you need to back up your data and replace the hard disk immediately. After this prompt, there is no other solution except to replace the new disk.

If no hard drive is detected. The first thing to consider is the hard disk. As long as the hard disk is powered on, it is constantly running, and the speed is more than 5,000 rpm. These mechanical structures will inevitably fail. When testing the hard disk in CMOS, you can listen to the sound from the hard disk. If the sound is: "Da ... Da ... Da ..." and then the calmness is restored, you can be sure that the hard disk is probably no problem; "Da ... Da ... Da ...", and then the sound of "click ... click" several times in a row, there may be a problem with the hard disk. In the worst case, a periodic noise such as "Da, Da, Da" appears on the hard disk during the self-test, which indicates that there is a problem with the mechanical control part of the hard disk or the transmission arm, or the disk is seriously damaged. How much is the temperature of the hard disk normal? In order to further judge, you can remove the hard disk, connect it to other computers, and then enter the CMOS to test. If it is not detected, then it can be concluded that it is really a hard disk problem.

After the overclocking, “hard disk read / write failure” occurs, this is likely to be a problem with the hard disk. Many hard disks will have some problems when working at high FSB. In some cases, the hard disk cannot be started. In the other case, the data is lost. You can try to reduce it to MODE 3 and shorten the length of the hard disk cable as much as possible. 100M 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 FSB is about 92M (that is, the PCI speed is 46M). Under this condition, almost all hard disks cannot afford it.
