In general mobile hard disk normal access to the computer, my computer or computer disk management can see the symbol of the new hard disk, the most simple and direct into my computer can see the new mobile hard disk symbol, she did not see can wait refresh to see under my computer, my computer management View.

① When encountered removable hard disk does not show we first check whether the mobile hard disk data cable connected to the computer and mobile hard disk no, sometimes not plugged in, the computer does not recognize the mobile hard disk more, another mobile hard disk USB connection good, we look to the host USB to accept whether adverse, a change in the interface to try, the front will not do, for the back and try again. Computer crash? Computers often crash how to do?

PS: Some computer front USB interface did not connect to the motherboard interface, leading to the front USB interface can not be used a lot, so this also needs attention.

②Ensure that the host computer USB interface is available, and the 50Ft SVGA VGA Monitor M M Male To Male Extension Cable and hardware connections are secure, mobile hard disk is still unable to show we can try to re unplug host US interfaces, wait insertion to try again, I encountered this The case began to access the computer prompts due to equipment access, but not see the mobile hard disk drive letter in my computer, but repeatedly re-plug a few results there.

③ First up to try to get another computer, if normal, is the matter of your system, if not normal, that is, your hard disk or hard drive USB cable. Find a good USB cable to try it first, or not work is the hard disk, repair, and general hard disk will not repair.

Own system from the Device Manager to see whether the abnormal icon in front of the mobile hard disk, such as the question mark exclamation point, you add new hardware, re-find, and check under the computer services whether banned service, it can not and do not know where the problem friend can restore the system to normal (eg: a key to restore or reinstall the system), and then connected to the test, most problems can be solved. There are problems ... the last time to see the BIOS settings or the BIOS back to factory settings, does not work, check your motherboard.

Two situations:

1) the computer's USB port itself is not a high-speed interface, and removable hard disk for high-speed hard disk, so even energized normal can display mobile hard disk; You can view the computer's USB port, general computers have several USB interface, if the pre-effect bad, as much as possible to use set USB, and is best connected to the USB interface on the mobile hard match. Tip the print spooler service is not running "solution!

2) mobile hard disk on the power supply requirements, if the computer's USB port is insufficient power supply mobile hard disk as lights, there will be speed, but to take power, and can not operate normally, of course, will not be displayed on the computer mobile hard disk drive letter.

Of course, the above is to ensure that mobile hard drive is good, if it is unable to determine whether the removable disk available notebook trial, because the notebook to a removable disk power supply is powered double-headed disk data by moving the line, in general, the mobile hard disk suddenly recognize the disk, there are several possibilities. First, check the USB interface, for the trial of a USB interface, if conditions change a computer test, to remind here, try to set the USB interface connected to the computer after, because the chassis front USB interface possible voltage instability. Secondly, removable disk cartridge, reinstall or replace a removable disk cartridge and data lines to try; Finally, if you exclude the above problems, there may be the fault of the disc body, should stop the energized try, if the hard drive is still in warranty went Warranty . Over the warranty period, and the data is not important, you can use the MHDD detect bad sectors, but to do the operation from the disk, in DOS, swept out of the red and green blocks, MHDD also comes with a repair function, you can try to use mobile hard disk repair tools for mobile hard disk repair, repaired recommended after this hard drive is not recommended to save important data, because this hard drive may have been faster problem can not guarantee that data can save long lost important data more harm than good.

We use the vast majority of mobile hard disk and U disk are using a USB interface is a plug-and-play type. We often use the USB device also may encounter a situation that does not recognize the mobile device, that can not find the drive letter of the USB device.
