Sorry for the slight necro-post on my first post here, but I came across this same situation *twice*, and found a solution both times. I only post it here because when I google this particular problem, this is one of the first results that comes up, so I figured having a solid solution on this thread would be a good idea.
Setting proper ownership and permissions is on the right track, but there's an additional step that seems to need taking when dealing with some of these folders (*especially* folders on the root directory of the drive, as that's where the issue seems most prominent in my case).
When setting new permissions to allow yourself to delete the folder (via Properties (right-click) -> Security (tab) -> Advanced (button) -> Change Permissions (button)), you should definitely make sure you uncheck the first checkbox ("Include inheritable permissions from this object's parent") and check the second checkbox ("Replace all child object permissions with inheritable permissions from this object"), although that second checkbox is only needed if there are folders you want deleted in the folder you're trying to delete. It'll ask something about deleting permissions when you click OK, go ahead and agree to do what it asks. After that, you should be set to delete the folder.
Up until I did that last step, I was running across the same permission issues with deleting folders (Windows telling me I needed permission from "GamesoulMaster" to delete a folder when I *am* GamesoulMaster is very frustrating). Of course, I can understand the issue in my case, where it's inheriting permissions from the drive itself (being a folder in the root and such). Still, it's frustrating, but this should help a lot of people who are having this problem and haven't found the solution with the suggestions in this thread.
