What happens if the hard drive is not powered enough, and will the insufficient power supply on the

Yes. The main mechanical part of the hard disk is composed of the following parts:

Spindle motor: used to drive the platter to rotate at high speed, most of the current hard disks use liquid bearing motors, with extremely high precision, and the gap may become larger after a violent collision, and it becomes difficult to read data, abnormal noise or cannot detect the hard disk at all.

Voice coil motor. Closed-loop control motor for accurate positioning of the head on the track.

Head: used to read or write hard disk data, it is easy to be damaged when it is violently collided, resulting in the hard disk is not recognized. The head is more likely to be damaged after a crash.

Disk: Stores data and rotates the platter at high speed driven by the spindle.

Positioning card: It is used to make the head stay in the start and stop area, and the positioning card is easy to be misaligned when the hard disk suddenly loses power, resulting in the head not being able to seek normally.

The hard drive is damaged either by a violent collision, by a sudden power outage, or by insufficient power supply. When the power supply is insufficient, the disk runs from high speed and suddenly stalls, which will cause the head to fall, touch the disk surface, damage the head or scratch the disk surface, and cause damage to the hard disk.

Let's take a look at some of the classic power supply failures.

The storage device is not recognized, and there is a strange sound on the hard disk.

When you finish upgrading the accessory and can use it normally, but sometimes it will stop at the self-test screen after booting, because one or more of your IDE SATA storage devices cannot be started by self-test, to put it bluntly, some storage devices cannot be recognized normally. If you check that the cable and power supply are connected correctly, and that there is no problem with the cable and the IDE SATA port of the motherboard, you may want to look at the power supply.

This kind of failure usually occurs after the player replaces a storage device such as a hard disk drive, or adds a storage device when the power supply is aging, such as using a combination of "dual hard disk + single optical drive" and "single hard disk + optical drive + recorder". In the case of insufficient power, the group of power cords corresponding to individual storage devices loses power supply, and the equipment cannot work normally, and it is very normal that it cannot be recognized normally when it is turned on and self-test.

In addition, with too many storage devices, or the power supply is too low, it cannot cope with the best storage devices in terms of power supply, and it may cause damage to the storage. After some users have upgraded, they find that the hard disk will make a strange "gurgling" sound from time to time, and the optical drive and recorder often enter a dead loop when reading the disk. At this time, users must pay attention to the fact that if this situation continues, the hard disk and other equipment may be permanently damaged, because their "abnormal" operation is caused by insufficient power supply, and you should try to avoid letting the hard disk work in a low-voltage environment.

To solve this kind of problem, the symptomatic way is to reduce the storage devices on board, hard disks and optical drives that are not commonly used, it is best to remove their power and data cables, and the root cause is of course to change to a higher power power supply.

Insufficient power supply on your computer will affect your hard drive. If the power supply is insufficient, the running speed will be slow, no response, or it will directly crash and restart. If the power supply is not enough, the hard disk is relatively easy to damage, 1. The insufficient power supply will cause the hard disk to work at non-rated power, if the computer is reading the data in the hard disk at this time, suddenly the head reads to a certain point and stops, because the reading and writing are abnormal, the head moves frequently, and it is easy to produce bad sectors.

2. Unstable voltage can also cause the chassis power supply to work at non-rated power, resulting in insufficient head speed, resulting in scratching of the hard disk.

The power supply is the heart of the computer, and if the power supply is insufficient, the power supply is not enough, and no matter how good the configuration is, it will not play anything. Therefore, the installation must choose a power supply with sufficient power, and the voltage range should be wider.

Recently, due to the low level of hard drive, I saw the opportunity to buy a gold diamond 40GB boxed hard drive from the computer market.

Hurry home, open the case, set the new hard disk as the main disk, install the old hard disk in the same IDE port, and connect the last power connector. After booting up, divide the new hard disk into two areas, reinstall windows98, and everything is OK. A few days ago, when I turned on my computer and copied the disc with a CD-ROM drive and recorder, a blue screen suddenly appeared, prompting an error to read the C drive.

No way, after restarting, use the software to disinfect the virus, and no virus was found. Format the C drive, and if there are bad sectors, check the C drive with SpecialDisks (SPF). Sure enough, there are quite a few bad tracks.

I quickly removed the hard drive and took it to the dealer for testing, but I didn't find any problems. Helplessly, I took the hard disk back and connected it again, and the fault was still there. So I unplugged the data cable of the old hard disk, but the problem was still there.

I was also a little anxious, so I simply came to a thorough and unplugged the data cable and power supply of the optical drive recorder. Boot troubleshooting, that's when I realized my. The old power supply is 250W, is it because the power supply is insufficient to cause the detection of bad sectors in the hard disk?

With the mentality of giving it a try, I connected the two hard disks and the recorder, the optical drive was not connected, and the boot was detected by SPF software, and there was no problem. The cause of the fault was found and solved, and it was effortless, so I went to the second-hand market, spent dozens of dollars to buy a 300W power supply and installed it at home, and there was no problem again. The above DIY experience hopes to help you eliminate similar problems.

Seven hurtful people: power supply problem, again power supply problem. Usually, the faults caused by the power supply have a certain degree of concealment, so when you deal with the kind of inexplicable faults, you may wish to think more about the power supply. ;

Of course, insufficient power supply can cause the computer to crash, restart, or shut down for no reason. In fact, the hard disk is also composed of high-speed head and optical disc-like components, and sudden power failure can easily damage the head and the internal disk surface.
