Why does the mobile hard drive not show when the phone is connected to the computer, mine is the new

Sony Ericsson K750 mobile phone memory is not a removable disk after connecting to the computer,You need to view the files inside you need to install K750 PC suit,There is it in the original CD。

If you want to read the memory stick, it is not recommended to connect it directly with your mobile phone, not to mention that the speed is super slow (, it is also harmful to the mobile phone battery. It is recommended to use a card reader for the management of memory stick files, and the speed is at least 5ms.

When some mobile phones are connected to the computer, you have to turn on the hard disk on the mobile phone to connect to the computer, or you just charge, you see where there is a button to open your mobile phone's hard drive.

It has nothing to do with the phone settings, maybe your driver is not installed, I don't know if you have a CD? Attach the driver and PC kit.

You can just open the installation and you don't have to install the wizard.

It should be a problem with your phone settings, you check the connection type in the phone settings,

The data cable does have this problem, specifically the driver.

It is recommended that the table use a data cable, and it is possible that the rookie will burn the machine if you are not careful.

Go buy a card reader, 13 yuan, worry-free

Or buy a Bluetooth adapter with a lot of silver, super easy to use, safety first

Summary. Hello, some portable hard drives have switches to turn on.

Plug in the USB disk and can't open it, and this page will be displayed all the time.

I want to open the USB disk.,It promotes, please insert the disk into g.,The page I just sent.,How to solve it.。

You are reminded of this prompt when you double-click on the USB flash drive to open it.

Right. Hello, you try to change the U port, and then do you have important files in the U disk.

Can you use this USB flash drive normally on other computers?

Yes, the USB flash drive is sometimes not compatible with the computer, you try to change the interface, if it doesn't work, you open the device manager.

In the Disk Drive in Device Manager, find the USB flash drive.

Enable or update the driver.

Summary. Method 1: Sometimes the reason for the failure to read the hard disk may be that there is a problem with the computer interface, and you can change the interface to try to read the hard disk data.

Plug the USB flash drive into the computer, right-click on the computer properties, select Device Manager, and check the update driver.

Method 1: Sometimes the reason for the failure to read the hard disk may be that there is a problem with the computer interface of the segment plexus, and you can change the interface to try to read the hard disk data. Method 2:

Apple mobile phone through the app store ** Brother Guo Recovery Master, open the software on the home page of the computer to restore the appointment service. Method 3: Insert the USB flash drive into the computer, right-click on the computer properties, select the device tube trapped burner roller, and check the update driver.

The above is the information I have found for you in your question, I hope you will find it.

I hope I can help you, it is my honor to be able to help you, I hope you give a thumbs up, thank you.

If you buy a new computer, plug in the USB drive and double-click to open this page.

Try a different socket.

How to operate, try to change the socket of the USB flash drive.

Same. Then you should find a professional maintenance personnel to check it out.

Summary. The new portable hard drive can detect but not show up, often for the following reasons:

01.It may be that the connection between the hard drive and the computer is loose.

It is not displayed on the newly purchased portable hard disk computer.

The new portable hard drive can detect but not show up, often for the following reasons:

The new portable hard drive can detect but not show up, often for the following reasons:

01.It may be that the connection between the hard drive and the computer is loose.

02.There is a problem with the hard drive itself (a problem with the main control chip).

If the computer doesn't display the one you bought and won, then you must not have separated it, and you can see it by sorting it out of the formatted QQ.

Unable to recognize, one is that the computer cannot recognize the U device.

The second is that the U device cannot be recognized by the computer. We first have to determine whether it is a problem with the computer or the USB device. We can use other U devices to test if there is a problem with the computer.

If it's a problem with the computer. Your computer is not corrupted by a virus. The driver is not installed well or the version is incompatible. There are no software conflicts (fix the software problem first) and generally come up with a prompt to install the driver.

If it's a computer hardware issue. Let's start by measuring the four lines of the U with a multimeter (red +5V

white data-data-data-

green data-data-data-

Black. Ground wire) multimeter red table pen to ground black table pen measurement (white line and 渌 line. The resistance value is not different by 50 ohms, these two lines are from the south bridge, if the resistance changes too much, it can be judged that it is the south bridge problem. Illustration U burned out the module inside the south bridge.

In the look at the outside of the U device now a lot of drivers are required. Even without a driver, it will not come out of the situation that is not recognized. There are several situations in which there is no recognition.

A U data cable is not through or the contact is poor, generally contact that place, because of a long time, there may be rust and swelling inside, and there may be something blocked inside. Two.

The US line is not working. If the red line is not passed, there will be no reaction, and if the white line is not passed, it will not be recognized. The green line is not recognizable. The white and green lines cannot be reversed. It is also unrecognizable. The black line does not pass and does not react, as mentioned above in this measurement method.

Note. The low voltage of 5V on the red line can also lead to unidentification.

Three, the internal problems of the US machine board. 1. The crystal oscillator is poor and does not vibrate. 2. Crystal oscillator capacitance defect (20p): There are two 3 reset capacitors with defective resistance. The reset voltage is too high at the bottom 4, and the three-terminal IC is not good, and the voltage provided for the IC is not enough 5

Portable hard disk is obviously a good solution that cannot be read on your own computer.
