If you are not able to open you hard drives or USB disks on a windows based PC by double click, then here is a simple procedure that will help cure your problem.
If you have found yourself having to open your disks or hard drive by following the path Hard drive, right click and then explore in My computer for the drive to open, then your Hard drive is infected with a virus.
This problem is generally caused by most of the viruses which infect windows OS systems. They block and restrict access to any of the drives.
Here is antidote for this problem:
In most cases when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.
This autorun.inf file is a read only, hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself. autorun.inf initiates all the activities that the virus performs when you try to open any drive.
You have to just delete this file and restart your system to correct this problem.
The following set of commands will help you to delete the autorun.inf
1. Open Start and go to Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.
2. type cd\
3. type attrib -r -h -s autorun.inf
4. type del autorun.inf
5. now type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Similarly repeat step 5 for all your hard disk partitions or drives.
6. Restart your PC and your troubles are no more.
