What should I do if the power of the portable hard drive is lost when it is working and it cannot be

A sudden power outage often damages the hard drive, which may already be damaged.

1. Go to the disk manager to see if there is a hard disk. If so, re-partition and format it. If you only have one hard disk, you can make a U disk PE on another computer and look at it under PE.

2. If you don't have a hard disk, go to the device manager and see if the disk has this hard disk. If not, the hard drive is completely broken.

3. Remove the hard disk and connect it to another computer, or use the hard disk base, or directly connect it to the inside of the chassis to see if it can be recognized. If it can be recognized, then install it back on the machine, and pay attention to changing the SATA interface as much as possible. If it is not recognized, replace the hard drive.

First of all, the hard disk is dialed out when copying things, at this time the head does not return to the zero position, due to the dial-out is affected by the current, dialing out is easy to cause physical damage to the platter, your situation is likely to have been damaged, you have also tried a lot of methods, can not succeed, you can try it according to my method, the general problem can be solved, first find a machine with the same hard disk, hang this hard disk on this computer, use ghost to copy that hard disk to your bad hard disk, generally can be restored to the basic usable, Then use the hard disk detection tool to check the bad location, repartition, and divide the bad part into a separate area, in the use of the computer, this area is no longer used, it can be hidden, just do it. It's just that hard drives are cheap these days, and you don't usually have to do it, unless you're a tech-savvy person. Ask me again if you have any questions.

It can be repartitioned and formatted with PQ Hard Drive Partition Magician.

In the future, don't be in a hurry to format this situation, if the mobile hard disk has a reset button, if the reset does not work, then format it.

NTFS format is recommended.

Have you tried low-level formatting?

Once ejected, just unplug the power supply.

The so-called damage refers to the sudden power loss of the hard disk when reading and writing, and the head may hit the disk and cause damage.

After normal ejection, the head is already in a safe position. But the disk is still spinning, and there is no problem with unplugging at this time.

Power failure is a hard wound in the hard disk.

du！Here's how to fix it:

The substitution method can be used from large blocks of parts to small pieces back to parts.

a. Change the computer and try to eliminate the problem of the mobile hard disk or computer.

b. Change the hard disk enclosure and try to rule out the problem of moving the hard disk enclosure or the hard disk.

c. After the above elimination, the problem can be determined. Just find the appropriate solution.

d. According to your description, it can be concluded that the problem lies in the large part of the mobile hard disk, but it is a problem with the hard disk enclosure or hard disk, and you need to further rule it out.

e. If the hard disk box is broken, replace it, dozens of dollars, the hard disk is broken, and the warranty will be provided within the warranty period. Of course, if your mobile hard drive is a finished product that you bought and is still under warranty, then go directly to the warranty.

Is there an abnormal copy sound on the hard disk after powering on? A sudden power loss of the hard drive may cause damage to the circuit board or damage to the head motor. If the power is on, the hard disk does not rotate, it is mostly because of the circuit board, if there is an abnormal noise, then the head or motor problem.

If the hard disk is still under warranty and does not need the data in the hard disk, then you can find a new hard disk after sale.

Hi, are you trying to connect to a different interface or to a different computer?

Is the same issue occurring?

Also, did I try to reinstall the driver, do I get the same issue as well?

If you haven't already, try the steps below to reinstall the driver.

In fact, if you want to talk about power failure protection, you have to start with the working principle of Winchester hard drive.

Nowadays, a large number of hard disks other than SSD media are Winchester mechanical hard disks stored in magnetic media, which can be seen as a stylus moving at high speed on a magnetic record to read data. However, the scale of this process is much smaller than that of a record, and generally speaking, the distance between the hard disk head and the platter can be as close as 10 nanometers! So that's why a power outage can easily damage the hard drive, simply put, a sudden power outage will cause the high-speed moving head to suddenly lose control, and there is a great possibility that it will fall on the platter and cause physical damage to the delicate magnetic platter.

However, in order to prevent this damage, most of today's hard disks have added a power-off protection technology called head priority homing. That is to say, when the hard disk is suddenly powered off, there will still be enough power in the hard disk circuit to ensure that the head can return to the stop position without losing control.

Completely handwritten, I hope it can help you If you have any questions, feel free to ask

At present, there are no portable hard disks with power failure protection related functions.

Today's mobile hard disks are a notebook hard disk plus a hard disk enclosure, in order to be lightweight, so the structure inside is very simple, that is, a hard disk enclosure, a circuit board and a hard disk, there is no battery and other devices that can continue to supply power. However, hard disk manufacturers consider that sudden power failure will damage the hard disk, so they are also constantly researching new technologies, such as most of the current hard disks have added a power-off protection technology called head priority homing. That is to say, when the hard disk suddenly loses power, it is guaranteed that the head can return to the stop position without losing control, so as to protect the platter from damage at the moment of power failure.

With this technology, it is possible to protect the hard drive not only in the event of a power outage, but also when the computer is running low on power.

Finally, it should be reminded that although the mobile hard disk has a large capacity, it is also a relatively delicate thing, and it is not only necessary to plug and unplug it correctly in daily life, but also to avoid vibration, especially when reading and writing data, do not move it.

Mobile hard disk is generally not damaged, often this is definitely not good for the hard disk, but the mobile hard disk connected to the TV to watch movies itself is slightly different from the computer, the computer can eject the mobile hard disk, and the TV cannot, so when the movie is being made, the hard disk is rotating at high speed, so the power failure has a certain impact on the mobile hard disk, it is recommended to turn off the TV and then pull out the mobile hard disk is more appropriate.

The problem of bad sectors is more complicated, any hard disk that leaves the factory can not be regarded as completely free of bad sectors, collisions during transportation, in the installation of **, moving during use, and even in normal use may produce bad sectors, products, always have a lifespan, mobile hard disks can not be used continuously for 10 years, so don't care too much, power failure has little impact on mobile hard disks, the important thing is not to fall in the move.

If the number of times is not much, you can rest assured, in fact, the harm is not very great, depending on the character.

Some U disks and some mobile hard disks, if the time of Changzhen is not powered, will not have a certain impact on the data inside the travel book, because the principle of storing data in U disks and hard disks is through the transformation of data, and there will be no certain impact. And the U disk records data by changing some females on the disk, and the internal storage of the U disk is also similar to the storage of the solid state disk, so if there is no power, it will not have a certain impact on the internal magnetism, so this worry also has certain doubts. <>

And recently, there are also people who want to put the USB flash drive into some time capsules, but the data is stored to a certain extent. The main feature that affects the data of the USB flash drive is to prevent the USB flash drive from not being carried out some. As long as the U disk is placed in some relatively constant temperature environment, even if it is kept without power for ten years, then it will not have a certain impact on the internal data of the U disk, so the U disk is also a very good stupid macro.

However, like the solid-state drive, it must be powered on frequently, because the solid-state drive is saved by some flash memory particles, so it still needs to be powered on to a certain extent. However, like mobile hard disks, there is no need for certain protection, because the principle of mobile hard disks and USB flash drives is the same, and it is also through acute changes to carry out certain data processing. So let's go to the treasure of the execution of some USB flash drives.

The parts of speech of the U disk are well preserved, so the data of the U disk will not disappear to a certain extent, but some collisions may cause some internal parts of speech to be changed to a certain extent, and some internal parts to be damaged to a certain extent, then, the data inside will have a certain impact. Therefore, if you want to store USB flash drives and portable hard disks for a long time, then you still need to store them in a dry environment. Therefore, for the preservation of U disk and the protection of mobile hard disk, then it can be normal protection of data.
