Laptop external hard drive not showing up

What to do if the computer’s external hard drive does not show up

Solution: Replace the BIOS battery and re-enter the BIOS to detect the hard drive. 2) The IDE cable is of poor quality or not plugged firmly.

Connect the mobile hard disk, enter the device manager to uninstall the mobile hard disk driver, then click on the main menu, operation, scan and detect hardware changes, and the mobile hard disk driver will be automatically reinstalled.

First of all, please check whether the hard drive power connection is correct and make sure the power cord is firmly connected. Also, consider replacing the power cord with another power plug. If the data is accidentally lost, it is recommended not to read or enter new data into it at the first time. You can try to use some data recovery software to recover the overwritten files.

The solution to this kind of situation is not difficult. It can be solved by making correct settings according to the BIOS instructions of the motherboard and the hard disk itself.

When the drive letter is not displayed when the mobile hard disk is connected to the computer, you can right-click "Computer" and select the "Manage" item from the pop-up right-click menu.

If there is no prompt in the lower right corner of Computer, you need to rule out whether there is a problem with the interface and driver of the computer itself. After changing the interface and updating the driver, there is still no prompt. I need to further confirm whether there is a connected mobile hard disk.

How to solve the problem when the hard disk is not displayed when plugged into the computer

Try to reconnect the hard disk: Reconnect the hard disk and check whether it can be read normally. If it still cannot be read, you may need to use data recovery software to recover your data. If your hard drive stores important data, please do not format the hard drive easily. You can try to use professional data recovery software to recover data.

Just unplug it and try to plug it in again. See if it can be displayed after plugging it in again. If it still doesn't work, you can try another slot. There may be dust in the current slot. Another option is to use another hard drive to see if it displays the problem to rule out whether the power supply is damaged.

What should I do if the hard disk is plugged into the computer, but the computer does not display it? If it is a brand new hard disk, you need to enter it first, repartition the hard disk, right-click, and after completing the format, you can open it in the resource manager. See the hard drive.

Connect the mobile hard disk, enter the device manager to uninstall the driver of the mobile hard disk, then click on the main menu, operation, and scan to detect hardware changes. At this time, the mobile hard disk driver will be automatically reinstalled.

The system does not find or recognize the hard disk after booting. This situation causes the system to be unable to start with a hard disk. Even if the computer is started by other means, the hard disk cannot be found.

What should I do if the external hard drive cannot be displayed? The USB is not recognized by the computer. If it is due to the system or the driver that comes with the system, you can fix it as follows. Press F8 on boot to enter safe mode and then exit. Select restart or shutdown before booting to enter normal mode (repair the registry).

The laptop cannot detect the hard disk

1. The USB is not recognized by the computer, if it is due to the system or the driver that comes with the system. Press F8 on boot to enter safe mode and then exit. Select restart or shutdown before booting to enter normal mode (repair the registry). Set CMOS parameters.

2. In the "Drive Letter and Path of Mobile Hard Disk" window, click "Add" to solve the problem. Detailed steps: Open your laptop, find the "My Computer" icon and right-click on it. In the pop-up properties window, find the "Manage" option and click on it.

3. Another problem is the voltage, especially if the optical drive position of the notebook is changed to the hard disk position. It may be that the low-voltage interface causes insufficient power supply and the hard disk cannot be displayed. Another possibility is that the hard drive is broken.

4. When this happens, it can basically be determined that there are bad sectors on the hard disk, or there may be a problem with the hard disk firmware. You can use bad sector checking software to test whether the hard drive has bad sectors. The hard drive is running normally but cannot be detected by the BIOS. After starting the laptop, the hard drive is not detected in the BIOS, but the hard drive is running normally.

5. Type 1: The computer cannot detect the hard disk or cannot recognize the hard disk after the win7 system is turned on. Many people may think of the hard disk compatibility mode issue. However, it is rare that there are compatibility issues between the hard drive and the motherboard, and they can usually be eliminated first.

Why does the computer not respond when the mobile hard disk is plugged into the laptop?

1. Because the high-speed mobile device is plugged into the low-speed hub, the device may not be installed normally, and some friends still use the mobile hard disk at the same time. When using a USB flash drive, for convenience, just use the USB 1 standard connection cable that comes with the USB flash drive. This will cause the USB 0 standard mobile hard drive to not be recognized correctly.

2. First find the “This Computer” icon on the desktop. Right-click and select Manage. The Computer Management dialog box will pop up. Click "Device Manager" in the list on the left. Find "Unknown Device" in "Other Devices". Right-click and select Uninstall. Now re-insert the external hard drive.

3. Why my mobile hard drive plugged into the computer cannot be displayed? It may be caused by one of the following reasons: First, please check whether the hard drive power connection is correct and ensure that the power cord is firmly connected. Also, consider replacing the power cord with another power plug.

4. First, you must determine whether it is a computer problem. Plug it into the rear USB interface or try another computer. Secondly, you must troubleshoot the mobile hard disk box and data cable. It is best to disassemble it. Move the hard disk box and try to connect the disk body directly to the slave disk. You can also replace a box and data cable.

5. Insert one end into the hub and the other end into the hub completely. The USB interface of the computer thus solves the problem of insufficient power supply. Plug in the two USB plugs on the mobile hard drive. Maybe the mobile hard drive is not enough! This is actually powered from the keyboard port PS 2 port (the USB cable comes with the PS 2 port).
