The computer does not recognize the mobile hard drive how to do

The computer does not recognize the mobile hard drive solution one:

Generally speaking, mobile hard disk normal access to the computer, in My Computer or computer disk Management can see the new hard disk symbol, the simplest direct access to my computer can see the new mobile hard disk symbol, the beginning did not see can wait for a refresh of my computer to see, can also be viewed in my Computer Management.

① when encountering a mobile hard drive does not show that we first check that the data cable of the mobile hard drive is connected to the computer with the removable hard drive no, sometimes because it is not plugged in, causing the computer can not identify the situation of mobile hard disk is also more, in addition, when the mobile hard disk USB connection is good, we look at the host USB reception is not good, change the interface to try , the front is not good, change back to try again.

② when the computer host USB interface is available, and the data cable and hardware are firmly connected, the mobile hard disk still cannot show we can try to unplug the host US interface, a little wait to insert again to try, the author encountered many this situation, began to access computer prompts due to equipment access, But in my computer can not see the mobile hard drive letter, repeated Plug and pull a few results have.

③ first to get another computer to try, if normal, is your system, if not normal, is your hard drive or hard disk USB cable problem. First find a good USB cable to try it, or not is the hard drive thing, send repair it, the general hard drive we will not repair.

If it's your own system, you look at it from the Device Manager, move the hard disk before the exception icon, such as the question mark exclamation point, and so on, there will be added new hardware, to find again, and check the computer service is prohibited by the relevant services, it is impossible and do not know where the problem of friends can restore the system to normal ( Such as: A key to restore or reinstall the system, and then take the test, the general problem can be solved. There are still problems ... The last time to see the BIOS set up or restore the BIOS directly to the factory settings, not yet, check your motherboard.

The computer's USB interface itself is not a high-speed interface, while the mobile hard disk is a high-speed hard drive, so even if the power is normal can not show the mobile hard disk area, the computer's USB interface, the general computer will have several USB interface, if the effect is not good, as far as possible using the rear USB It is best to receive a USB interface that matches the removable hard disk.

As a result of the mobile hard drive on the demand for power, if the computer's USB interface power supply, mobile hard drive will be the same light, there will be speed, but due to lack of electricity, can not operate normally, of course, will not display on the computer mobile hard disk letter.

Computer does not recognize the solution of mobile hard disk two:

1. The CMOS parameters are not set to open for friends who have never used USB external devices, it is possible that the system cannot detect a USB hard drive even if the driver is properly installed, mainly because the default CMOS port on the motherboard is turned off, and if it is not set to open, Then Windows naturally cannot detect the removable hard drive.

To solve this problem, we can reboot, enter the CMOS Setup window, and in the "Pnp/pci CONFIGURATION" column, "Assign IRQ for USB" is set to "Enable", This allows the system to assign an available interrupt address to the USB port.

2. Computer power supply due to the USB hard disk in the work also need to consume a certain amount of electricity, if directly through the USB interface to take electricity, it is likely to appear power shortages.

As a result, almost all mobile drives come with a separate external power supply or a PS2-turn interface that is powered by a keyboard. At this time as long as the prior connection to the external power supply or through the PS2 to connect with the keyboard, to ensure that the mobile hard disk to provide enough power after the test, then should be normal use of it.

It is important to note that it is recommended that you make sure that you have enough power before using a removable hard drive, or you may be damaged by a lack of power.

3.USB extension Cord Failure to remove the above two reasons may be the USB interface type does not match the mobile hard disk can not be used. For example, the computer configured USB interface is 1.1 standard, and the purchase of the mobile hard disk is the USB 2.0 standard interface, which requires connecting the computer and mobile hard drive connector must support the USB 2.0 standard.

Because a high-speed mobile device is plugged into a low-speed hub, the device may not be installed properly, and some friends use a USB drive while using a mobile hard disk, which makes it easy to use the 1.1 standard connector that comes with the USB 2.0 standard, which results in the correct identification of the mobile hard drive. This failure can be resolved simply by replacing the connector with the USB 2.0 standard.

4. Improper system setup for some users, after installing the driver, you can view the removable hard disk icon from Device Manager, but there is no corresponding letter identification in the explorer, which is caused by improper system setup.

Double-click the move hard drive icon in Device Manager and click on the pop-up window of the "Properties" button, you can see the disconnect, removable, synchronized data transfer and INT13 unit four options, which "can be deleted" in front of the system default is not ticked, as long as the option to restart the computer, You can see the new mobile hard drive letter in the resource manager.
