The computer can recognize USB, but cannot open the U disk and indicate "access denied". The device manager indicates that the device is working properly. What is the reason? How to solve?The problem is when the system is reloaded. There is no virus.
What antivirus software installed, ah, what firewall, you have banned it?
Belonging to the mobile disk, can change computer to try, if still, under a U disk repair tool, not a production tool to mass production.
What do you charge for soft killing (antivirus software) check your kill soft?!!!According to experience, it could be ESET NOD32!After the default installation of the ESET NOD32, it will remind you to block access to the U disk, which may prevent U disk access if you are not aware of it.You turn on the advanced settings and then allow access to OK..If it weren't for ESET NOD32, the same thing...
U disk access denied, you can follow the following steps to repair:1) into the "start running", enter the regedit to open the registry editor, the "HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionexplorerAdvancedFolderHiddenSHOWALL" branch, and then find the binary sub key "Checked value" in the right window, "Checked value" instead of "1 keys".2) in the tools folder options, select show all files and folders, so that you can show them.3 in the U disk will see four files, namely floder, destop, destop2 and autorun.inf, the four all deleted.4) after you find a hidden file RECYCLER in the U disk, delete this folder.5) find the [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon] branch and change the key value of the key of "Userinit" to "userinit.exe"".6) in the process, the current user name under the wuauserv.exe and svchost.exe end.7) enter the c:windowssystem32svchost directory (note that svchost is a folder, not a program) and delete all of this directory. This is done, the U disk pulled down and plug in, you can use it normally.
