This could be irriversible from within Windows. You may need to use a tool like a Linux boot CD or Partition manager to change the drive format from NTFS to something else. This will remove the NTFS permissions and perhaps let you access it again.

Start an elevated command prompt:

cacls I: /t /c /G YOURUSERNAME:F /P YOURUSERNAME:F

Press enter.

Try this attached program. Unzip it and run the "Take ownership" reg file. This will give you a right click option in the drop down menu to take ownership. I have not used it on a complete harddisk but it works succesfully on folders and files.
