My hard drive was still recognized by the computer a few days ago, but it can t be recognized when p

Connect the hard drive and make the system on it!

Check whether there is a problem with the SATA cable and power cable of the hard disk, if there is no problem but the hard disk is still not recognized, it may be a bad sector of the hard disk, you can use it".Partition Assistantto format the hard drive to fix the bad sector problem.

I don't know what kind of situation it is when the problem is not recognized, the colorful smart motherboard uses Intel 945PL+ICH7 chipset, SATATII interface, supports up to 2T STAT hard disk, and SATA3 interface is backward compatible, so even if the newly bought 1T hard disk is SATA3 interface, it should theoretically be able to reduce the specification.

To solve this problem, we can start from the following aspects (in order):

Judge whether the hard disk has power supply: after plugging in the hard disk and turning it on, gently touch the hard disk, under normal circumstances, you should be able to feel the power of the hard disk on and rotate, if you can't feel the power on, please check whether the power interface is abnormal, if possible, you can use a multimeter to test whether the output pin has voltage, if the hard disk is not powered on, please consider changing the hard disk to a power supply for testing;

Determine whether the data cable interface is plugged in or whether the data cable is damaged: Please use multiple data cables to test on different data cable ports;

Check whether the SATA interface is disabled in the BIOS: Reset the BIOS with a discharge or perform a soft reset in the BIOS to see if it is normal.

If none of the above fails, cross-test the drive on a different machine to determine if the drive is damaged.

The hard disk is not recognized on the computer, and the TV cannot be opened, what is the problem?

SATA hard drive.

On the side, the wide is the power supply line, and the narrow one is the data line, you can look for it.

Old-fashioned. IDE hard drive.

The wide ones are the data lines, and the narrow four wires are the power lines.

1. If the system cannot recognize the hard disk, you can troubleshoot and solve it as follows:

If the BIOS cannot recognize the hard disk, disassemble the chassis and confirm the SATA interface and whether the power cord of the hard disk is loose.

2. If there is no abnormality in the interface check, it proves that the hard disk has been damaged and cannot be used at this time. If you can identify the hard disk, check whether the hard disk capacity, speed and other information are correct, and then continue to the following steps:

3. Disassemble the hard disk and mount it on the SATA interface of another computer, or use the mobile hard disk enclosure to use it as a mobile hard disk. Then boot the other computer into the system, open the disk manager, and confirm whether the hard disk is recognized, if not, it proves that the hard disk still has a hardware fault and cannot be used;

4. If it can be recognized, right-click and select "initialize" it, and then partition, format and other operations, then the hard disk can be read and used normally.

The hard disk used in the notebook computer is generally inches, and the desktop is inches, due to the different technical parameters of the manufacturing process of the two, first of all, the hard disk only uses one or two disks to work, and the hard disk can be assembled with up to five to work; In addition, due to the large disk diameter of the hard disk, it can provide relatively large storage capacity; If you only compare the area density storage capacity, the performance of the hard drive is also quite satisfactory. Laptop hard drives are one of the few universal components in laptops, and basically all laptop hard drives can be universal.

However, laptop hard drives have a parameter that desktop hard disks do not have, that is, thickness, and standard laptop hard drives have 7,,,4 thicknesses. The hard disk is designed for ultra-light and ultra-thin models, and the hard disk is mainly used for the larger thickness of the optical and soft interchange and the fully built-in model, as for the hard disk is the product of the previous single disk capacity is small, basically no model is used.
