Why does my hard drive keep ringing and it runs super slow when it does!! 20

In this case, the hard disk may only have a life span of a few months at most, and it is recommended that the data inside be backed up and replaced with a hard disk No one expected it to be suddenly reimbursed one day, and the data in it is all chicken and egg, not cost-effective After all, hard disks are valuable, and data is priceless! ～

My hard disk is the same, I used it for more than 5 years, and it has been ringing in January this year, and then the system does not recognize the hard disk, and I only know when I go to repair, so that it is broken, and the life is up, but fortunately I have a backup, I am Seagate 80, and now I have a Seagate 500, hehe.

Use fdisk to repair bad sectors after backing up important data.

It's better to buy a new hard drive, fix the old one, and use it from the disk to install games, movies and other less important things.

It's even bad.,I guess it won't take long.。。 It is recommended to dispose of it as soon as it is still available.

In my experience, it's good to add a ground wire, and my computer has been like this, but why can't I say it's good, it won't sound after adding, it's weird.

The hard drive is about to hang. Be prepared.

The sound of the hard disk is different, some are loud and some are small, mainly because of different brands, but the volume of the hard disk has a reasonable range, and it should not be too loud. Generally, there are only two possibilities for you to have this situation, that is, your hard drive is slow or damaged, and the second situation is that it is aging for a long time or there is too much dust. If your hard drive is not very full and there is still this situation, it is most likely the first case.

There are a lot of such problems in recent years, and it is definitely a hard disk problem. Now the quality of things is not as good as before, and I have replaced the customer with 2 new hard drives. It can be replaced during the warranty period, so you might as well try it.

The hard drive is not used for a long time. If it is new, it is recommended to take it to the merchant to exchange.

The hard drive sometimes "clicks" inexplicably, and today I will help you solve this problem.

First of all, I checked the chip of the circuit board, when the fault appeared, I tried to touch the chip on the circuit board of the hard disk with my hand (first release the static electricity), the chip is not hot, and sometimes the hard disk can be read and written normally when booted, the chip should be normal, so it can be considered that the hard disk failure is not caused by a problem with the chip.

As we all know, when the hard disk works, it needs a stable voltage and sufficient current, if the voltage is unstable or the current is insufficient, the operation of the spindle motor will be affected, which makes it difficult to seek the magnetic arm, that is, if the power supply voltage or current of the hard disk changes too much, it will cause the change of the speed of the hard disk, and then there will be inaccurate positioning or error in the positioning of the magnetic arm, resulting in no normal reading of data or an increase in the bad sectors of the hard disk. The hard disk often makes a "click" sound, which may be caused by the abnormal operation of the hard disk and the continuous positioning of the magnetic arm due to the instability of the current.

Since the hard disk failed because of a problem with the chip, it may be due to the instability of the voltage, so I checked the voltage of the input and output of the hard disk. The power supply of the hard disk is 5V and 12V, you can use a multimeter to test, the voltage is too high and too low, and it is normal to have a fluctuation of 10. When the hard disk fault occurs, I carefully used a multimeter to detect the voltage at the interface of the hard disk, and found that the voltage is within the normal range, then it is not the problem of the power supply, then the problem is in the interface circuit of the hard disk.

Through the above analysis, it can be known that the problem of the sudden "click" of the hard disk is not caused by insufficient power supply or damage to the hard disk control chip, but by the poor contact between the hard disk circuit board and the magnetic arm power supply interface of the hard disk body. The part connected between the circuit board of the hard disk and the power supply of the disk body is not a pin or flexible cable, but a crimping method, because the hard disk is used for a long time, coupled with the poor working environment, the tin plating layer of the interface of the circuit board and the oxidation of the spring blade of the disk body, resulting in poor contact between the two, resulting in unstable power supply of the magnetic arm seek motor, and abnormal seek and the hard disk can not work normally.

Knowing that the problem of the hard disk may be in the **, then you can prescribe the right medicine, the solution is very easy, disassemble the four screws that fix the hard disk circuit board, carefully remove the circuit board (there is a line on the circuit board connected to the spindle motor, do not tear it off), pick up the circuit board, there will be two rows of spring pieces on the side of the circuit board close to the four-pin power interface, and carefully polish the contacts of each spring sheet with water sandpaper or a frustration knife. At the same time, the corresponding contacts on the circuit board should also be polished and bright, and then the circuit board can be put back as it is. Be careful to remove the grinding metal debris, otherwise it may cause a short circuit.

Finally, I tested it on the computer, and it was finally done, reinstalled the system on the hard disk, scanned and detected with Norton and other disk utilities, and found no errors, and then ran continuously for 12 hours without failure, and the hard disk will no longer have a big "click" sound (

The hard disk clicks, the computer is stuck, the bird cannot enter the system, the reading is slow, the hard disk is not in a hurry to scrap, just a screwdriver can be repaired.

There are two reasons why there is a problem with the hard drive

1.Hard disk soft bad sectors: often called logical bad sectors, can be easily fixed – repartitions can be formatted clearly (partitions cannot be the same size as they were originally).

2.Physical bad sectors: cannot be repaired, can only be shielded (the location of the bad sectors is divided into a zone and then deleted, or the bad sectors are written into the P table of the bad sectors with MHDD and PC300 to shield).

Be careful not to use hard disk detection software running in Windows without accuracy to detect, you must use the only tool for professional hard disk repair in Computer City MHDD.

Is there a bad sector?,Use HD Tune to check it.。 Defragment the disk before identifying bad sectors.
