I'm running Windows 7 64-bit, and I've mounted my previous computer's Vista 32-bit hard drive through an external enclosure so that I can access my files on my new computer. I can access every part of the drive except my old User folder (C:/Users/John).
When I attempt to access it, it prompts me for the administrator password (which it didn't need for any other part of the drive) and then loads infinitely.

Letting it load doesn't seem to do anything. The harddrive is constantly working but nothing is happening. I find it extremely strange that it's just the E:/Users/John folder I can't access, but it doesn't even work when I run as Administrator.
Any help?
