Computer hardware, like an external hard drive, is extremely important for day-to-day computer usage as it enables the user to store extensive data, as well as share that data from one computer to another seamlessly. WDPassport 500 GB is one such hard drive. Normally the system recognizes the hard drive automatically when connected, and the icon appears in My Computer. However, it may be that the system fails to recognize the WD device. It is easy to solve this problem. One needs to change the Drive Letters and Paths or go through the Registry Editor to make the necessary changes.
