Have A Broken Partition That Cannot Be Deleted, Formatted Or Resized

I have this broken partition on my computer. If I open it in the disk administrator it says that it is formatted. The problem is that it isn't formatted correctly and that I can't read it, change it's properties or delete it. If I try to do anything with it the tool says that the file is not found.I really want to delete it to get the space back. What can I do? The problem is likely that my harddrive has recorded somewhere that a partition exists while it in reality doesn't. Is there a way to make my computer realize that it is actually unallocated space?

Here's the eventlog error code: 80070002@020A000D
