I have never used eraser or vista before.  I am trying to erase all unused disk space but when I execute that task I get a complete with errors message.  The log says: The program does not have the required permissions to erase the unused space on disk.  Run the program as an administrator and retry the operation.  I am an administrator.  I tried closing eraser and relaunching and had the same results....any ideas?
This is Vista Home Basic BTW.
