Broken partition 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?

Run Disk Check


What tool are you using? Use Disk Mgmt or Partition Wizard installed version to make use of its Check File System feature.

If it fails Then run the HD maker's HD Diagnostic extended CD scan.
