The NTFS file system provides built-in security controls in Windows NT, 2000, XP, Vista, 2003, 7 and 2008. An NTFS-secured hard drive will appear locked in another system. You can't access the drive because the NTFS permissions are set up for users that don't exist on your system. The only way to correct this problem is by taking ownership of the hard drive. To take ownership of a hard drive or partition, you must be an administrator.
