Hard disk power failure, SSD hard drive afraid of sudden power failure?

250W power supply, if you use a discrete graphics card, it is really a power shortage.

Bad power cord? Take a multimeter and test it to know.

12v+10% is normal.

12v-5% is normal.

Outside of this range is not normal.

+ is not a robot +++

Addendum: Since the dream of titanic says that there is a table of numbers, it is best to do it.

Dreaming of titanic says that dreaming of titanic understands the actual measurement, and it is better to do it).

Connect the load test, connect the hard disk, the actual measurement, if , it means that the dream of titanc's Huntkey, Great Wall, Jinhetian, or other brands of power supply --- excellent.

Connect the load test, connect the hard disk, the actual measurement, if , it means that you dream of titanic's Huntkey, Great Wall, Jinhetian, or other brands of power supplies--- free of strong combination (no longer happy).

Reasons for not being happy:

Chips usually have little power and don't use as much power to pull the voltage down.

Consider that there is a problem with the power supply of Ttanic's Huntkey, Great Wall, Jinhetian, or other brands in the dream, or the cable from the power supply of Huntkey, Great Wall, Jinhetian, or other brands to the hard disk is too thin or the interface is not in good contact, or the hard disk chip is a little problematic.

The lower limit of ATX 5V is 5V-5% = , and the dream of Titanic is already below.

If you dream that Titanic is connected to a discrete graphics card, can you dismantle it and give it a try, it is a big power guster.

If you dream that Titaic has another hard disk, connect it and test it again according to the method above, still?

It's still just a dream of titanic's Huntkey, Great Wall, Jinhetian, or other brands of power supply is inadequate!

As far as cgul25 knows.

12V is for the hard disk motor motor, 12V+10% is normal, 12V-5% is normal.

Very good. 5V is the chip integrated block that supplies the hard disk, 5V+5% is normal, and 5V-5% is normal.

is the chip manifold that supplies the hard disk, % is normal, is normal.

The cgul25 was tested a few years ago and the internal hard drive was not required.

I don't know if the new hard drive this year has been used.

cgul25 suggests dreaming of titaic:

Since I was able to search for these words in the know: "ATX Power Specification 12V 5V 5% Fluctuation Range", it is necessary to dream that Ttanic did it himself, and the CGUL25 failed to do it for him.

All of the above is cgul25 typed by hand.

Hard drive goes warranty.

Don't dwell on it. Go to the warranty quickly.

It should be that the power of the power supply is not enough, and it is recommended to change to a 300W power supply.

Is it more than 10 minutes before the hard drive is disconnected? If so, it may be that your power settings are set to turn off the hard drive in a few minutes, and there is a power option in the control panel, check the option to turn off the hard drive as "Never".

Sure enough, the power supply is very small, the power supply is small and can't support so many parts, 250W is a very early configuration, you can change the power supply, get a 350-450, 200 yuan to get it.

In addition, the small power supply voltage will also lead to problems such as not being able to turn on the machine at one time, restarting it several times before turning it on, or even not turning it on.

The SSD hard drive is not afraid of sudden power failure, because it does not have any physical movement mechanism, and there is no stopping impact.

But the data is afraid of power failure, the data that is being read and written, if the power is off, it will also cause file content errors, but the SSD hard disk itself has no effect, check it with a disk check tool, and the error part can be used normally.

When the hard drive experiences an abnormal power failure, it may cause damage to the internal structure of the hard drive, and may also lead to data loss or damage. Therefore, in order to avoid this from happening, it is best to use UPS or backup power to protect the device to ensure that the hard drive can shut down gracefully and prevent data corruption in the event of an unexpected power outage.

Dear, I'm glad to answer for you that the abnormal power failure of the hard disk refers to the interruption of the normal operation of the hard disk due to sudden power failure and other reasons when the hard disk reads and writes data. This situation may lead to corruption or loss of data from the hard drive. In order to avoid abnormal disconnection of the hard disk, users can take the following measures:

1.Use an uninterruptible power supply (UPS) to protect computer systems and hard drives so that power can be provided in the event of a power outage. 2.

Back up important data regularly so that it can be recovered in the event of data loss or corruption. 3.When performing hard drive read and write operations, try to avoid accidental power outages or shutdowns.

4.Check the health status of your hard drive regularly and fix any issues in a timely manner. If the hard field disk has experienced an abnormal power outage, users can try the following methods to recover the data:

1.Use data recovery software to try to recover the data. These software can scan the hard drive and try to recover corrupted or lost files.

2.Connect the hard drive to another computer and try to access the data on the hard drive. 3.

If the hard drive has been severely damaged, users may need to seek professional data recovery services. 

SSDs are integrated circuit storage that require continuous power on during the read and write process. Therefore, for SSDs, once an abnormal power failure occurs, it will not only cause the loss of data that has not yet been saved, but also cause errors in previously written data in extreme cases, making the SSD unable to be recognized by the system.

The reason why the SSD is abnormally powered off and bricked is because the SSD stores an FTL table in the internal DRAM cache, which records the metadata necessary for the normal operation of the SSD, which has nothing to do with the data that the user wants to store, but plays an indispensable role in the normal operation of the SSD. The danger of abnormal power failure is that these metadata are lost and damaged, resulting in the SSD being unable to read and write normally.

A sudden power outage can affect the SSD, from data loss to read-only or a sudden reduction in capacity.

1. Solid-state drives are more afraid of power outages, and sudden power failures will cause data damage.

2. Because the SSD has a wear and tear balance mechanism, that is, when the user is not using the computer, it will automatically move and transfer data in the background. In other words, although the user does not use the hard disk to read and write, the hard disk reads and writes on its own. At this time, if the power is suddenly cut off, it is easier to lose data.

3. Moreover, there are more serious ones. Some SSDs suddenly lose power, and then turn on the machine to become read-only. Others will suddenly shrink in capacity. Usually it is possible to flash the firmware. Of course, although the hard drive can continue to be used, the data is lost.

4. Now more and more solid-state drive manufacturers are adding power-off protection to their new products. That's why.

Hard disks are all the same, it can't be said that it is not afraid of power outages, power outages have a certain impact on hard disks, so it is personally recommended not to illegally power off without illegal power failure.

The hard disk is not affected, but the data is being read and written, and an error may occur.

There is no damage to the hardware, but there is a possibility that the data being read and written will be lost

It may cause the head not to return, but the current hard disk is relatively better, you can rely on the remaining power after the power failure to make it home, don't happen often This kind of data is not lost, and the current hard disk head drive is used "voice coil motor", which in the structure ensures that the head will automatically return to the position (back to the start and stop area) at the moment of power failure. So I don't think there is any harm to the hard drive from the hardware side, that is, it will not cause physical damage, and it will not produce physical bad sectors. Because a normal shutdown is also a sudden power outage for the hard drive (from a hardware point of view).

The only difference is that it ensures that no reads and writes are done at this time.

2.If the hard drive is in the middle of a "write" operation, it will cause data loss, partition table disorder (corruption), and other consequences. It even produces logical bad sectors.

However, apart from the loss of data, there is no damage to the hardware of such a hard drive. Just repartition or format it to get back to normal.

3.Sudden power outages that cause physical bad sectors or even damage to the hard drive are not completely unavoidable. Just like hard drives can also produce physical bad sectors or even damage during normal use. Just a coincidence and a special case.

Frequent power outages may cause disk errors, so run a scan of disk, and the Windows system will automatically run a scan the next time it starts, if it aborts unexpectedly and a disk error occurs.

However, power failure is mainly damage to the hardware of the computer, such as the power failure when the disk is reading and writing, it is possible to damage the disk, these damages are physical, except for replacement or repair, there is no way to repair it by soft methods.

Today's hard disks have better performance, and in the event of a sudden power failure or unexpected abort, they will use the residual power stored by themselves to automatically return the head to their own location, which largely avoids physical damage. But it's certainly harmful to always lose power.

In addition to the damage to the hard disk, the motherboard and graphics card also have a certain impact. It's better to buy a UPS. It is an uninterruptible power supply, which can supply power to the computer immediately in the event of a power failure, so that it is not affected by the power outage and shuts down normally for an effective time. If you don't have that, you're backing things up. This is just to see, in case the hard drive is broken, this may also be useless.

Either you have to grasp the law of power outages and cut off the power yourself when a power outage may occur.
