So I installed Windows 7 fresh a couple days ago, and now when I hook my backup drive up for some reason when I open the My Videos folder I had saved (and every folder inside it) I get a "you don't have permission to access this folder" error. It tells me what to do to fix it and it lets me open up the folder after I do so, but when I try to play the video it says "file not found" even though it's clearly there and taking up space. These videos were on this hard drive before I ever used Windows 7, and they worked fine on my last Windows 7 install. I also am using the secret administrator account, and strangely enough, when they worked on the previous install I was just using a user account. What's going on, and how can I fix this? Preferably the entire videos folder at once if possible, since I have about 30 folders inside it...
