I got a Western Digital 40 gig hard drive for my digital camcorder (can we say hours of kinky movies?) and I was wondering if somone can tell me whats involved in putting this in. I have a CD-ROM and a CD-R drive already, am I gonna have to change their letters or anything? I can't imagine this will be too hard, so anything you guys can tell me would be great. I will not be running anything off this drive, it will just be for storage. Thanks guys.
