You can find the LCN (Logical Cluster Number) of the first MFT cluster at
the Offset 0x30. Please note that this is a 64bit value (0x30-0x37). The LCN
of the MFT-Mirror is located at Offset 0x38 (0x38-0x3F).

You can find some NTFS documentation at the Linux-NTFS project at
http://linux-ntfs.sourceforge.net/ .
