In our daily study and office work, U disks and mobile hard drives are portable storage devices that are often used. However, during use, failures will inevitably occur. For example, we often encounter situations where the computer cannot recognize the mobile hard drive. So, how do we solve the problem of mobile hard disk not being recognized? do not panic. The editor will share with you the method to solve this problem.
The editor found that recently some friends wanted to know the solution to the problem that the mobile hard disk cannot be recognized, so Xiaozhuang spent some time understanding the solution to the problem that the mobile hard disk cannot be recognized, so now we solve the problem that the mobile hard disk cannot be recognized. Share this question with you.
1. It may be that the USB power supply is insufficient, causing the mobile hard disk to fail to start normally. Inadequate power supply may exist from the beginning, or it may suddenly occur one day. The reason cannot be determined specifically. It may also be a system setting or removable hard drive failure.

2. When the mobile hard disk is connected to the computer, it will be powered through the USB interface and connected to the data interface at the same time. It can provide 0.5A current, and there will be no problem in general data copying. However, the front panel interface design of older motherboards is imperfect and often leads to insufficient power supply, resulting in data loss and even damage to the hard drive. We must pay attention to these situations.

3. As far as power supply is concerned, generally speaking, the power supply from the USB interface is sufficient. However, you may encounter situations where two interfaces need to be connected at the same time, so users are best to purchase a data cable with two USB interfaces when purchasing to avoid insufficient power supply.

Some users may turn on the energy-saving mode by default when using the system, which may cause insufficient power supply to the USB interface, resulting in intermittent failures in the USB interface.

5. Right-click My Computer/Properties/Hardware/Device Manager and double-click the Universal Serial Bus Controller. We will see many options. Double-click on any one to open the properties dialog box.

6. Switch to the Power Management tab, delete the check before allowing the computer to turn off the device to save power, click OK to return, modify the properties of each USBrothub and then restart the computer. USB devices can resume stable operation with as low a frequency as possible.

7. In terms of data cables, we mainly face failures caused by interface compatibility and incorrect connection of the front USB cable.
First, let’s talk about the problem of wrong laps. If the USB cable on the motherboard is connected to the front USB port on the chassis, incorrect polarity may cause the USB device to burn and may seriously damage the motherboard. During repeated use, the rear USB interface should be used as much as possible, and the positive and negative levels should be carefully identified when inserting.

8. Mobile hard disk status analysis: The problem of the hard disk itself is the problem of the hard disk itself. The method is very simple. If some brands of mobile hard drive boxes cannot be opened at one time, you can directly connect the removed hard drive to the computer case. Now mobile hard drives are basically interfaces.
