How to hide a drive letter in Windows XP

In the following tutorial, I explain how to hide a drive or drive letter from being displayed in My Computer. This is useful if you don't want just any average user to be able to easily detect, access and navigate a hard disk that is attached to your system. Note that the drive can still be accessed from explorer by typing in the drive letter. Because we are going to be editing the system registry to hide the drive letter you should proceed with caution, as it is possible to do irreversible damage to your system if you make a mistake.
