Why can t the hard disk be detected when the computer reinstalls the system?

Yours may be SATA hard disk,You go into BIOS to see if there is a hard disk option like SATA,Change ACHI to C (I can't remember a long list) compatibility mode,After installing the system, go to the next SATA hard disk drive,After installation,Change it back from BIOS,I hope it will help you。

This is mainly caused by four aspects, one is the power interface and the power interface of the hard disk, the second is the data cable, the third is the hard disk interface of the motherboard, and the fourth is the circuit problem of the hard disk. The above kind of failure will occur after a long time of time. If the machine is new, it may be a problem with the power supply of the hard disk and the hard disk.

First, the power interface can be replaced with an access.

Second, the data cable can be replaced with a new one, and the data cable is relatively cheap.

Third, there are multiple hard disk data cable interfaces on the motherboard, which can be connected to another one.

Fourth, if the above problems are not solved, then you can only look at the hard disk.

SATA hard disks need to be loaded with drivers when they are installed.

Your system disk may not be powered by SATA. I recommend that you boot into the BIOS, then change the hard drive mode to compatibility mode, and then install the system. After the installation is complete, install the SATA driver, and then change the hard disk mode in the BIOS to SATA.

Alternatively, you can simply use a system CD with a SATA driver to install it.

To add: like I said, your machine is now SATA, and your CD doesn't have SATA drivers, only PATA, which is the IDE driver, so it can't detect your hard drive. You'll need to change to a disc with a SATA drive, or change the hard drive mode in the BIOS.

Workaround for reinstalling the system and not detecting the hard drive:Brand model: Shenzhou K650D i5 D2

System version: Windows 10

Software version: USB flash drive boot.

1. Turn on the computer and enter the small eye interface and press the F2 key on the keyboard.

2. Enter the BIOS interface of the computer, press the arrow key to the right, find the boot, and select the first one with the arrow key down.

3. Press the Enter key, continue to use the arrow keys to select the USB flash drive to start, then go back to the position of the menu, switch to the exit interface, then press Enter, and select Yes.

4. Enter the PE system, click on the guide repair, and click on the drive letter.

<>5. Click Partition Tools, click Disk in the menu bar, and then click Rebuild Master Boot Record.

<>6. After the reconstruction is completed, click the restart button to continue the operation of step 1, and then you can find that the hard disk appears.

The solutions are:

1. It is recommended to enter the safe mode for diagnosis and start.

2.The hard drive may not be detected by the computer.

3.If your computer detects the hard drive every time and can't access the system, reformat the hard drive and reinstall it.

If it doesn't work, it is recommended to go to a repair shop to fix it to avoid bigger problems.

The solution to the problem that the hard disk cannot be detected by the reinstalled system is as follows:

1. BIOS Settings: Restart the computer, and then click the BIOS boot hotkey continuously (usually F2, DEL, ESC, different computer brands, which can be seen at the bottom of the boot logo interface). The BIOS interface appears.

2. Check whether the hard disk is in poor contact or the hard disk line is falling off. Remove the main chassis, plug the hard disk cable again, or remove the hard disk and press it to another computer for detection, if it is also not detected, it can only mean that the hard disk is damaged and needs to be replaced with a new hard disk.

Can the hard drive be detected by the motherboard BIOS? If the hard disk can be detected, it is recommended to replace the PE software or update the PE software, which may be that the PE is too old to support the hard disk port. If the hard disk is not detected in the motherboard BIOS, it may be that the hard disk cable or hard disk is broken.

If the computer cannot detect the failure of the hard disk, you need to check the data cable and power cable connected to the hard disk to see if there is a problem of poor contact, or replace a hard disk to test it.

Find out why your computer doesn't recognize your hard drive.

After troubleshooting, it's time to install the system!

Can you see the hard drive in the BIOS? If you are sure that the hard disk can be seen in the BIOS of the computer, it means that the system disk you are using does not load the corresponding hard disk drive information, just find a system with the latest hard disk drive loaded and install it.

Hard disk is one of the main storage media of a computer, consisting of one or more aluminum or glass discs. The disc is covered with a ferromagnetic material. The following is the solution to the hard disk that I collected and sorted out when the computer is installed, welcome to read.

The solution to the problem that the hard disk cannot be detected when the computer is installed

Disk boot failure, insert system disk and press enter prompt when the computer is booted, causing the computer to be unable to enter the system normally, what is going on? In fact, this problem occurs mainly because the computer cannot find the hard disk when it is turned on. So, what should I do if I can't find the hard drive when my computer turns on it?

The hard drive could not be found

1. After entering the BIOS first, select the "IDE HDD Auto Detection" item to see if the hard disk can be detected. Yes, and check if the model is consistent, if the hardware problem is ruled out normally, if the drive cannot be found, then your hard drive is damaged or connected incorrectly.

2. If the hard disk can be viewed in the BIOS, generally the main boot sector of the hard disk is damaged, you can use the PE system with DOS toolbox to run the DOS command "fdisk mbr" to try to repair the main boot sector of the hard disk.

3. If the method in step 2 does not work, you can try to restore the BIOS to the default settings.

4、。Sometimes there is some kind of error in the system, which may cause the system to not recognize the hard disk, use the system installation disk to repair the system or reinstall the new system.

5. If it is a hardware failure, it is recommended that the customer dial in and open the computer case to plug in the relevant wiring of the hard disk, if the problem cannot be solved, it is recommended to send it to the service station for maintenance.

The reasons and handling methods for not finding the hard disk by reinstalling the system with a USB flash drive are as follows:

1) The first reason: that is, the hard disk mode is different, resulting in the use of U disk reinstallation does not recognize the hard disk, because most of the hard disks of the computer are serial port hard disks, and the ordinary XP installation disk and the Ghost version of the installation CD, they do not integrate SATA control driver (or some are also integrated, but do not match the actual SATA control driver), resulting in incompatibility, and can not identify the hard disk, resulting in the inability to install the operating system or blue screen normally, so it is necessary to change the mode of the hard disk, change the AHCI to IDE mode, and the hard disk can be recognized and the system can be installed normally.

Solution: Press DEL, go to BIOS, find advances---SATA CONFIGARATION---stata mode selection--change AHCI to IDE F10 to save OK, or select "Devices ATA Drives Setup Configure SATA AS IDE", and finally press F10 to save and exit BIOS.

2) The third reason: the main boot record MBR of the hard disk is wrong, which will also lead to the failure to recognize the hard disk when installed with a USB flash drive, and Jianyi rebuilds the master boot record MBR

Data Development:

1) Hard disks include solid-state drives (SSDs), mechanical hard disks (HDDs), and hybrid hard disks (HHD, a new hard disk based on traditional mechanical hard disks); SSD uses flash memory particles for storage, HDD uses magnetic disks for storage, and hybrid hard disk is a kind of hard disk that integrates magnetic hard disk and flash memory.

2) Hard disk technology: head reset energy-saving technology: by resetting and adjusting the head when idle.

Multi-head technology: It is used in servers and database centers to speed up the disk by adding multiple heads to read or write at the same time on the same disk, or to use the head to read or write to the disk at the same time on multiple disks.

3) The capacity of a hard disk is measured in megabytes (MB MIB), gigabytes (GB gib) or terabytes (TB TIB), and the common conversion formula is: 1TB = 1024GB, 1GB = 1024MB and 1MB = 1024KB. However, hard disk manufacturers usually use GB, that is, 1G = 1000MB, while Windows system still uses the word "GB" to represent the "GiB" unit (1024 conversion), so the capacity we see in the BIOS or when formatting the hard disk will be smaller than the manufacturer's nominal value.

The capacity metric of a hard disk also includes the capacity of a single disk of the hard disk. The so-called single-disk capacity refers to the capacity of a single disk of the hard disk, the larger the single-disk capacity, the lower the unit cost, and the shorter the average access time.
