Unable to open drives on double-click: How to solve it

Sometimes we get a buggy thing happening with us when most of our USB slots are filled up and we try to open a disk-drive by double clicking and we can't open except using  right-click options. 

Well, many post and many suggestions go for checking the virus-stuff in the USB drive providing links to many third party tools and other anti-virus options.
On the contrary of all these superficial tweets....I found my problem solved through a simple handling with the computer management tool for disk management.
Before jumping on to the steps for solving the problem, I would like to highlight that the main cause for this problem is due to external disk(s) connected with the system bus. Each disk drive is allotted a unique letter from C - Z. Sometimes due to multiple connection, there may perhaps be a collison for the names and the system cannot recognize them. So,it does not allow it to be open through d-clicking!

How to solve it..

You must be logged on as an administrator to perform these steps.
If you don't like the letter Windows has assigned to a new drive or you want to organize your drive letters in a certain way, you can change the drive letter.
You can assign the letters C through Z to each drive on your computer. A and B are usually reserved for floppy disk drives, but if your computer does not have floppy disk drives, you can assign A and B to volumes. You can see which drive letters are used on your computer by opening Computer.

Now do the following:

You can change, add, or remove a drive letter by using Computer Management.

>>Open Computer Management by clicking the Start button , clicking Control Panel, clicking System and Maintenance, clicking Administrative Tools, and then double-clicking Computer Management.  Type the password(If needed) or provide confirmation.

>>In the Navigation pane, click Disk Management(It can also be simply reached by right clicking  My Computer icon and selecting Manage).

>>Right-click the partition or drive that you want to change, and then click Change Drive Letter and Paths.

Do one of the following:

**To assign a drive letter if one has not already been assigned, click Add, click the letter that you want to use, and then click OK.

**To change a drive letter, click Change, click Assign the following drive letter, click the letter that you want to use, and then click OK.

**To remove a drive letter, click Remove, and then click Yes to confirm that you want to remove it.

Remember:

 MS-DOS and Windows programs make references to specific drive letters. If you change a drive letter, some programs that you have installed on your hard disk might not work correctly.

You cannot change a drive letter if the drive is either a system partition or a boot partition. If you get an error, the partition or drive you are trying to change might be in use. Close any program or window that is using the partition or drive and try again.
    Have a nice hack!!
