The impact of a power outage on your computer. Ask for an answer thank you for being more detailed

If there is a sudden power failure, the head is likely to cause damage to the hard disk, that is to say, the hard disk is in high-speed rotation during the reading and writing operation (usually 7200 rpm or 5400 rpm at present), if the power is suddenly cut off, it may cause the head and the platter to rub violently and damage the hard disk. It's like using something to scratch a mark on the hard disk, it doesn't matter once or twice, after a long time, just like the disc we use, there are many scratches on it, which will definitely cause the disk reading to be poor, and the phenomenon reflected on the hard disk is that there is always one when reading the disk"Phew""Phew"sounds.

However, since the service life of the hard disk is generally six to eight years, it is limited to infrequent power outages, and the damage to the hard disk should be within a tolerable range. I've been using IBM glass disks for eight years. After countless power outages, the hard drive now has nothing but booting or working time"Phew""Phew"Outside of the sound, there was nothing else abnormal.

Resources.

Damage to the disk, produce bad sectors, bad sectors are like viruses will be infected, and bad sectors should be isolated in time after they occur.

There are two kinds, one is the impact on your use, that is, the content of what you are doing without saving will be lost. For example, if you are writing an article on your computer, but the power goes out before you can save it, then the part you didn't save will be lost.

There is also an impact on your computer's hardware, the only thing that may have an impact is your hard disk, according to the speed of an ordinary desktop hard disk 7200 rpm, a sudden power failure, there is a certain possibility that the hard disk will be damaged, in this way, if the boot file or system file is damaged, your system will not be able to boot. Of course, now that the technology is relatively advanced, if it is not unlucky to the extreme, the chance of hardware damage caused by a power outage is still relatively small, don't be too afraid.

If you are really afraid, you can spend two or three hundred yuan to buy an ordinary UPS, two or three hundred yuan of UPS can make your computer not shut down within ten to fifteen minutes after the power failure, with these ten minutes, you can calmly save what you are doing, calmly shut down. You can protect your interests. Generally speaking, important computers, such as company servers, will use UPS uninterruptible power supplies.

It's just that they use thousands, tens of thousands, hundreds of thousands, which are better and more professional.

The impact is great, and it is easiest to burn the hard disk when there are more times, or the blue screen and so on, don't burn the computer like me and then buy UPS

I bought a new UPS computer power protector a few days ago, and the quality is also good, about the question of UPS purchase, or UPS's top 10 rankings, my space has been written in person according to my analysis of many UPS experience, I bought the first! It's just over a hundred

It is impactful and can easily damage the hard drive, but it may not be immediately apparent.

There is a lot of damage, first of all, it is more dangerous to the hard disk that is running, and it is easy to cause bad sectors. It is even possible to burn the power supply and motherboard.

There are several aspects of the impact on computers, which are analyzed from these two points:

1. From the perspective of the impact of power outages on computer hardware:

When the computer suddenly loses power, the power supply parts in the computer are cut off, and the rotating parts stop running, such as various fans, but this doesn't matter, the most pitiful thing is the hard disk.

The speed of the hard disk is 5400 or 7200 or higher, and when the power is suddenly cut off, the head has no power to maintain, so it cannot be suspended on the platter, and it collides violently with the platter, causing damage to the platter and damaging the data recorded by the platter. In short, the impact of a power outage on a hard drive can range from no impact or data loss to bad sectors (frequent power outages).

For hard disks, it should also be noted that today's hard disk shockproof and anti-power-off damage technology is still relatively advanced, when the hard disk is not reading data, the head will automatically return to a safe place, even if the power is suddenly cut off, there will be no damage to the hard disk, okay.

Second, from the impact of power outages on the soft aspects of the computer:

When the general work in operation is not saved and backed up in time, the sudden power failure is likely to make the previous work undone, and sometimes the loss will be very heavy.

1.Loss of data.

As long as the abnormal shutdown has an impact on the computer (including power outage), you may be performing some operations or office, sudden power failure may cause your work to be interrupted, file loss, and more serious may also lead to the loss of important files in the computer system, resulting in the computer can not start normally.

2. The hard disk is damaged.

Frequent power outages are the most serious damage to computer mechanical hard disks. When the computer is running, the disk inside the hard disk is always rotating at high speed, and the head of the hard disk will return to the zero track when the power is off, and the sudden power failure will cause the hard disk to return to the zero track immediately before the speed is slowed down and the platter will be deducted, which is very damaging.

Frequent sudden power outages will lead to bad sectors in the hard disk, which may lead to the loss of hard disk partitions and the direct non-recognition of the disk, then the data means that all the data may be lost, and then it will be regretted.

Even an SSD can't withstand a sudden power outage, and if it's an SSD that's reading and writing, then a sudden power outage can make the data permanently lost and unrecoverable!

3. The motherboard is burned.

If the computer loses power suddenly, and then the power is restored in an instant, the damage to the computer will be even greater, and in severe cases, the motherboard may be burned.

4. Affect the life of the host.

It will have a large inrush current for the main engine, which will have an impact on the life of the main engine!

5. The power supply is damaged.

There is no big problem with regular power supplies, and they are generally provided with protection modules. However, if it is some inferior power supply, especially the low-cost power supply that cuts corners, because there is no protection module inside, power failure is sometimes easy to cause power supply damage.

If you are in an environment where there are frequent power outages, and you are worried about the loss of important data on your computer due to power outages. It is recommended that you buy UPS backup measures, that is, uninterruptible power supply.

Plug the UPS directly into the power socket, the computer is connected to the UPS to work, when there is a power failure, the computer will not suddenly go out, and you can continue to work for a period of time.

Power outages can be very harmful to computers. Power failure may lead to the loss of important files in the computer system, so that the computer can not start normally, especially the most serious damage to the computer hard disk, which may lead to the loss of hard disk partitions, and the disk is not recognized directly, then the data may be lost.

The harm of power failure to the computer is mainly the hard disk, because the normal reading head of the hard disk is suspended, if there is a sudden power failure, the head is likely to cause damage to the hard disk, and the impact of the sudden power failure on the display screen is also immeasurable, and it may be burned.

Voltage fluctuations caused by the momentary power outage can impact the chips, circuits, resistors, etc. of computer hardware. However, if a disk read or write operation is carried out during a power outage, bad sectors may be generated, or data will be lost when writing manuscripts.
