The vast majority of the mobile hard drives and USB drives we use are in the form of a Plug and Play type. When we use USB devices, we may also encounter unrecognized mobile devices, that is, the USB device can not find the letter.

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. Why the computer crashed? How does the computer often crash?

PS: Some computers because of the front USB interface and not connected to the motherboard interface, resulting in the front USB interface is not available a lot, so this also need to pay attention to.

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.

In two different situations:

1, the computer's USB interface itself is not a high-speed interface, and 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 will be able to check the USB interface, the general computer has several USB interface, if the effect of the front is not good, It is best to receive a USB interface that matches the removable hard disk. Tip the "Printer Daemon service is not running" solution!

2, 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 power, not normal operation, of course, will not display on the computer mobile hard disk letter.

Of course, the above situation is to ensure that the mobile hard disk is good, if you can not determine whether the mobile disk is good, can be used notebook test, because the notebook to the mobile disk power supply through the mobile disk data line dual-head power, in general, the mobile hard drive suddenly do not recognize the disk, there First, check the USB interface, switch to a USB interface to try, conditional words for a computer to try, here to remind, as far as possible to connect the computer after the USB interface, because the chassis front of the USB interface may be voltage instability. Second, reinstall the Mobile hard disk box, or replace a mobile hard disk box and data cable to try; Finally, if the above problem is eliminated, it is possible that the disk body failure, then should stop continue to power the attempt, if the hard drive is still in warranty on the warranty. If the warranty period is exceeded, and the data is not important, you can use MHDD detect the bad way, but to do from the disk, in DOS operation, swept out of the red and green block, MHDD also brought the repair function, you can try to use the relevant mobile HDD repair tool to repair the mobile hard disk, if repaired well, It is recommended that this hard drive does not recommend saving important data, because the hard drive may have been quickly out of the question, can not guarantee the future data can be stored for how long, lost important data can not be worth the candle.
