However, sometimes when connecting the mobile hard disk to a Windows 7 computer, you may see an error message, that is, "Win7 does not display the mobile hard disk (Win7 cannot detect the mobile hard disk)". This situation is very common, but this problem does not mean that there is a problem with your mobile hard disk. In this article, we will share some ways and tips to solve this problem.I. Check the connection. First, you need to check the connection. Please check whether the USB data cable is normally connected to the mobile hard disk and computer. Sometimes, a loose connection may cause the mobile hard disk to be unrecognizable. In addition, you should try to connect the mobile hard disk to a different USB port to ensure that the port is working properly. If you use a USB extension cable, the problem may occur. If the USB extension cable is too long, it may cause signal loss, resulting in the inability to detect the mobile hard disk. You should directly plug the mobile hard disk into the USB interface of the computer to ensure that the signal is stable. II. Check the driver. If there is no response after the mobile hard disk is connected to the Win7 computer, it may be because the corresponding driver is not installed in the computer. Mobile hard disks usually come with a CD-ROM, which contains drivers and other related tools.You can insert the CD and install the driver. If you don't have a CD-ROM, you should search for the latest driver on the website of the mobile hard disk manufacturer and download it. III. Check the USB port. Sometimes, the USB port may be damaged or contaminated, resulting in the inability to detect the mobile hard disk. You can use some methods to eliminate these problems. First of all, check the USB port carefully to see if it is damaged or contaminated. If there is any damage, the USB port needs to be replaced. If there is pollution, you can use some cleaning techniques to remove dirt. IV. Use the device manager. If the mobile hard disk still cannot be detected after trying the above method, please try to use the device manager. Please press the Windows key + X key and select Device Manager from the shortcut menu. Find the disk drive and expand it.Below, you should see your mobile hard disk. If it is not displayed, right-click on the area and select "Scan Hardware Changes". This operation should be able to detect the mobile hard disk and solve the problem. V. Use data recovery software. If your hard disk still cannot be detected and works well on other computers, the problem may be caused by damage to the file system. You can try to use data recovery software, such as Recuva, to check the mobile hard disk and try to recover data. If the software can recognize and access the data, the problem may be caused by damage to the file system.
