You can't really hide a drive unless you write a driver, which is not possible in VB6 or install some sort of 'illegal' rootkit.

You can also hide a hard drive via the registry. It will hide the drive from "My Computer" and file browse dialogs, but it does not prevent access to the drive if people know the drive exists and manually type the hard drive path in Windows Explorer or the command prompt.
