The hard disk can still be used if the needle is broken, and the mechanical hard disk needle will be

Fault phenomenon: A few days ago, the author's system (WinXP) suddenly could not start up (the author's computer configuration: MSI KT333+8233A, WestJet Barracuda IV 60G), the phenomenon is that it has been stuck on the boot screen and cannot enter the operating system.

At first, the author didn't pay much attention to it.,I thought it might be a problem with the startup file.,Just fix it.。 But I tried several times but it didn't work.

Analysis and solution: The author thinks that the virus may be at fault, and the failure is still the same after the antivirus. After reinstalling the system, the boot speed is very slow, and the hard drive light flashes wildly.

After entering the system, the author measured the transfer rate of the hard disk and found that it was only 4MB per second! The author thought of the problem of transfer mode, open the device manager, sure enough, the hard disk works in PIO mode, the strange thing is that after I manually adjusted the hard disk working mode, after restarting the system, I found that the hard disk working mode is still PIO mode!

At this point, the basic problem has been found, the hard disk has lost support for DMA working mode. The author went to WestJet's official **** special tool to change the working mode of the hard disk, but it was detected that the default mode of the hard disk at this time was DMA, and I used the special error checking tool of the WestJet hard disk to conduct a comprehensive check. Everything turned out to be fine!

The author began to feel that the failure could be caused by hardware. After carefully inspecting the hard disk, I finally found that the problem was that the IDE interface of the hard disk was actually broken by a needle. The author quickly unscrewed the screws with the changing cone of the plum blossom mouth, removed the metal protective plate and sponge on the outside of the WestJet hard drive, exposed the circuit board, found a jumper pin from other places, repaired it to the original missing needle and soldered it.

Then restore the hard disk and reinstall the system to solve the problem.

It works, but some data won't read.

Try it yourself and find out.

1. First of all, it may be a switch problem, such as poor contact.

Solution: Turn off the switch on the back of the computer, or simply unplug it. etc. will be reinserted.

2. If it doesn't work, it may be that the computer has static electricity, causing adverse reactions.

Solution: You can find a piece of metal wire tied to the computer screw, and the other end is connected to the metal in contact with the ground at home.

3. It may be that the memory module is in poor contact, which is quite possible.

Solution: Remove it and erase it with an eraser. Then plug it back in, to be steady. Dual memory note compatible.

4. Computer fan problems. Fan problems will cause the system to determine that there is no fan, and in order to protect the computer motherboard, the computer will be forcibly stopped.

Solution: Check whether the fan is in good contact. Reinstall. It's best to add some heat sink.

5. Graphics card problems. This is also very family and capable, most of which are poor contact.

Solution: Remove it directly and reinstall it. The screws should be tightened, and the installation should be stable and slow.

6. Motherboard problems, if it's okay. It may be the motherboard, if it is a question of the Suiling of the Bureau, then you can only go to the repair shop to check if there are any problems such as bad sectors.

Extended Information: Common Troubleshooting of Computer Hard Drives:

1. It cannot be partitioned normally or cannot be formatted after partitioning.

In this case, professional repair software is used, generally according to different brands, the repair rate will be different, and under normal circumstances, there is a 50% chance of repair.

2. Do not turn after powering on.

In this case, it is generally a circuit board failure, and it is enough to replace the circuit board IC or replace the entire circuit board. After starting and turning, it depends on different situations and deals with them separately, but there are also some cases where there may be several other types of failures at the same time.

3. The self-test is normal, and the BIOS cannot recognize the disk.

There are many reasons for this, if it is a circuit board interface problem, the circuit board needs to be repaired; If the hard disk automatically enters internal protection mode, professional software switching is required.

4. After the power is on, the sound of the magnetic head does not stop.

In this case, the head is mostly damaged, and if you don't have to save the data, there is no need to replace the head to repair it; But if it's not a damaged head, there's only a 50% chance that it can be repaired.
