Hi,
My USB drive is enabled. The USB flash drive or any other storage device is recognized when connected to my laptop. But when I click on the drive in windows explorer, it says access denied. The same works fine in other laptops. I have admistror previlages. There is no local group policy set up on Removable storage access. I have searched multiple forums and tried out various options, but still cant connect to my USB drive. The drivers are successfully installed and are the latest. This happens even when I connect my camera or mobile phone. It shows up as 'Removable Disk' in windows explorer, but cant access it. I have given authorization to the drive as well. Please help.
