The computer needs to plug and unplug the hard drive to boot up 100

Take out the memory and change the slot, pull out the hard disk data cable, power on, and wait for him to find the hard disk, and then connect the hard disk power data cable, and the hard disk can generally be checked when booted. Mine just itchy hands to get it and can't find the hard drive. It's a good idea to clean up the dust from your computer.

1 Check if there is a problem with the line (most likely a problem with the data line).

2. Whether the power supply voltage is stable.

3 You can try system restoration, if it happens in these 2 days, you might as well try it, or it may work.

You check if there are any bad sectors on the hard disk, if there is, you don't want to fix it, just take it to the merchant to change, if there is no bad sector, you try to change the socket, or try to change the data cable.

Touch it to see if the system is overheating, or if the hard drive is overheating.

Also, please change the hard drive cable.

Use the hard disk detection tool to check the bad sectors, and then repair it, and generally one appears to be fine

The hard drive has bad sectors. Change a piece.

If you change the hard disk cable, you can install the system on the D drive.

First try to run the hardware repair software with the optical drive, to see what is wrong with the hard disk, if it is a small number of bad sectors, the software repairs, if there are a lot of bad sectors, try the low-level hard disk so that you can skip the bad sectors when reading data, generally 80g hard disk warranty period is within 3 years, not to take back the dealer to ask for a new hard disk.

Hot-swappable. In academic terms, it is called hot replacement, hot expansion, and hot upgrade.

Hot-swap technology is a key technology to achieve continuous operation and non-stop maintenance of power supplies. The most effective way to improve the reliability of the power supply system is to carry out redundant backup of key components of power supply equipment, replace the faulty power supply and expand the capacity of the system without interrupting the system operation, so the hot-swap technology of power supply has attracted more and more attention.

Test if the hard disk and memory module are unplugged and unplugged when the computer is turned on, will the computer burn?

After pressing the power button, keep pressing F2 (different computers may be different) to enter the motherboard BIOS, set the SSD as the first boot item, and then press F10 to save.

It's okay if you don't do it with electricity.

Is it not plugged in tightly or the chip is broken?

Whether the hard disk can be plugged and unplugged in the power-on state mainly depends on what interface the hard disk uses.

If it is a hard disk with SATA interface, then it can be hot-swapped.

If the HDD is IDE interfaced, it does not support hot-swapping.

The current hard disk is divided into two interfaces, one is the previous generation of PATA interface, which does not support hot swapping. Nowadays, most people use the more advanced SATA interface. This is hot-swappable. I don't know what kind of interface you have?

Because your motherboard BIOS has a protection function for portable hard drives.

As soon as you have a portable hard disk device, it will enter the portable hard disk, and it will not enter your main hard disk.

I've been like this! But that's more than one system on a portable hard drive! Cause conflict! And it can't be turned on! Later, a friend helped me set up to boot up and read one of the hard drives! It's ready to go!

Check the SATA interface connected to the hard disk.

If you have multiple hard disks, you need to connect the added hard disk to the SATA port with a large value.

For example, the previous hard disk was SATA2, then you need to connect to the interface after SATA3, otherwise it will affect the boot.

It may be that your bumps on the road have an impact on hardware such as the motherboard, and there is a situation such as desoldering, so it is better to take it to the store to repair it, and pay attention to the fact that the computer host cannot vibrate violently in the future.

It is recommended to replace the hard disk data cable and power supply, if it still doesn't work, it can only be said that it is a problem with the motherboard and the hard disk, but it is not bad, white. In other words, it is not compatible with the motherboard or hard disk and it should be no problem to change it casually, try it.

1 Your computer vibrates during transportation and there are loose accessories. It is recommended to check whether the accessories, such as memory, graphics card, and gold finger are in good contact. Whether the CPU is connected to the base in place, the power supply 24-pin and 4-pin power supply sockets, the hard disk power plug, and the cleaning of the inside of the host.

2. Due to the short circuit of the power supply 12V, 5V, and power supply line. Such as power supply hardware.

The obvious symptom of these failures is that the fan stops after two seconds. Depending on the information you provide, the power plug and hard drive may be the most common cause of failure.
