Okay, so I have some files that when erased turn up "Administrator Privileges Required" errors. So I run Eraser as an admin, and now I get "Access Denied" errors. I used FileAssassin to make sure the files weren't locked. Run Eraser again, and still no dice. I use v5, and I even upgraded to v6 to see if that would do anything. It didn't. My file system is NTFS, and I use Windows 7 Home Premium x64. Both versions of Eraser work on all other files, however it is these "special" files I'm talking about that refuse to erase. My Erasure method is the ol' good Gutmann 35-pass algorithm.
