* $Bitmap contains a bitmap covering the entire block device, including metadata and special files.
* $MFT contains block size, for computing bitmap offsets. This is usually 4096, for compatibility with stream compression, but it can be different.
* ntfsprogs ([http://www.linux-ntfs.org]) comes in handy: ntfsinfo --mft <dev> for block size, ntfscat <dev> \$Bitmap for bitmap
* This has to be the easiest of all, ironically.
