If you encounter such a boot, you can't find the hard drive and can't open the machine. What should I do? Solution

1 Do not use the computer in a humid environment for a long time, causing the components on the hard disk to get wet... Solution: Disconnect the power and heat the hard disk evenly with a hair dryer
2 Excessive ide devices on the computer As a result, the initialization time increases, but the corresponding self-test time does not increase, causing the system to fail to detect the hard disk or detect the timeout. The problem is more obvious when connecting to a system with multiple hard disks. After pressing the reset button, the device is initialized. Has been completed, so the fault no longer has a solution: find the "boot delay time" option in bios or "ld dedeay time", the time can be extended, the motherboard bios without this option, you can also check the memory The number of times is set to 3 times, and the self-test time is extended.
3 After the long-term use of the hard disk, the oxidation on the gold finger of the back circuit board causes poor contact. Solution: Remove the circuit board and clear the oxide on the gold finger. Maintenance personnel to clean up
4 hard disk physical bad sectors
Solution: If the above methods can not solve the problem, it is best to send the factory to repair, If you have important data, you must first go to the reputable data recovery company to recover the data.
5 Hard disk data cable and power cable loose, oxidized or broken. Solution: Try to change the power connector, data cable or ide/sata interface
6 Some motherboards have closed the sata interface, can not find the sata hard disk solution: to open the sata interface in bios
7 in the bios "standard cmos feaures" page, the hard disk is set to no.. Solution: set For auto, the
8 ide jumper is set incorrectly. The ide device of the hard disk and other shared data lines will set the jumper to “master” or “slave”. Solution: Change one of the ide jumpers.
9 Overclocking the system will cause the hard disk to not work properly Solution: Restore to default settings or reduce overclocking
10 Poor power supply or too much load on the device, may result in low +12v voltage output The hard disk does not work properly. Solution: Replace the power supply with better quality or higher power. The hard disk runs for a long time in an unstable power supply environment. It is very easy to cause bad sectors on the hard disk and cause data loss. Points to pay attention to.
