Every computer in our office has a mysterious drive X showing up in My Computer, showing the exact same storage capacity and free space as the original drive. Every computer has a drive C and a drive X and on first glance they look identical, but when you double click on drive X there's a bunch of random files that mean nothing to any of us. We took one of the computers off the network and scanned it for everything we could think of to scan it for, but we've had no luck with Google searches for this problem, so we have no idea what to do. I'd like to post a picture here of the screen but I don't see a link to upload a JPG.
