God opened the hard disk can be so repair! ?

Xiao Bian looked at the comments on the weekend when I saw a small partner asked to restore data. Many hard drives are not easy to use when they are damaged. It is very likely that they often read and write errors first, and then gradually develop intermittent hard drives. Calling, the last is the abnormal sound of the boot can not be used. Is there any way to repair the hard disk?

Why is the hard disk bad?

Xiao Bian once said that at present one of the most important hard disk killers is overheating, and one is a sudden power outage. Of course, there is nothing to be said about overheating. Xiao Bian has mentioned the problem of overheating several times, such as "fear of heat!" How warm is the computer temperature? 》 Suddenly the power failure is the same as that of bumping the hard disk. It is physical damage. In severe cases, the content cannot be recovered at all.

When the hard disk is broken, the performance is particularly obvious. When the computer is turned on or running, the hard disk will always whistle, and often the card reader will even crash. In this case, most of the head arm and disk "fight".

Let's take a look at what the hard disk really looks like to get a better understanding of why the hard disk appears this way. The inside of the hard disk looks very simple. The spindle motor clamps the disk disk. A voice coil motor fixedly controlled by a permanent magnet drives the head arm above the disk disk and finds the data on the disk by turning the track.

The so-called hard-disk howling sounds, in fact, the problem occurs between the head arm and the disk. The head arm will have an automatic home position according to the design, that is, the head arm will move out of the disk and be fixed (motor + permanent magnet) without power.

However, a sudden power failure is likely to destroy this mechanism, and when the impact is high, the head arm will also be attached to the disk (whether it is running or powered off, it will not hit the disk under normal conditions). In addition to the permanent control of the permanent magnets, the head of the head continues to traverse the disk after the power is applied. Imagine the sound of chalk drawn on the blackboard. This is almost like this (Yong Xiao Bian shivered __-).

Can a hard drive open cover be used?

The head arm scratches the disk, which is already irreversible damage. There will certainly be many bad sectors in the scan. If you try to save the hard disk with the idea of ​​saving data, opening the cover can be a method.

However, Xiao Bian should remind two points: First, the open hard drive will lose its significance after saving data (do not sell salted fish, data security is one, and second, do not encroach on other people). The normal situation should be Operate in a dust-free environment; second, be sure to open your lids with great care and attention, never reckless violence, otherwise the data will not be saved at all.

The hexagonal screwdriver is used to remove the hard disk and the specification is T6. The cover is not on the back of the hard disk, but on the front side of the hard disk, which is the labeling side. After removing the surrounding screws, there is a screw under the label paper. Locating the screws when you find the position is enough.

If the head of the head is on the surface of the disk when the cover is opened, it means that it must be caused by an abnormal power failure (whether it is a human operation or not, even if the control logic of the hard disk itself is erroneous). At this time, insert the T6 hex driver into the screw hole of the main motor and make preparations for counterclockwise rotation. It must be counterclockwise!

Then, pick up the elbow tweezer or small hook (home mother's crochet can be) to hook the head arm to the right to prepare for pulling.

The forceful method is as follows: Hold the main motor's T6 hexagonal screwdriver and turn it counterclockwise to apply force. Do not use too much force and apply force gradually. At the same time, hold the elbow rake or crochet in the other hand to drag the head arm to the right. Pull the head of the head arm too hard, must follow the screw driver's force, the head can be home!

After completion, cover the hard disk cover and tighten the screws, and check whether it can operate normally and be recognized by the computer (recommended hard disk drive box). If you can, after normal partitions are formatted, recovery of disk data using applications such as Genius or partition helpers is mostly possible. Of course, there must be a small amount of data that cannot be recovered, such as where the head arm passes over the area where the disk was damaged, and where the dust is contaminated.

The final Xiao Bian to say, this method of operation has a certain degree of difficulty, especially when dragging the head arm must be bold and careful, the best partner is best not to get, especially the shuttlecock or crochet pull head arm step . In addition, the data is recovered and backed up. The mission of the rescued hard disk is also achieved. Do not imagine that it can continue to exert its residual heat.
