DD is utterly filesystem-agnostic.. it only understands block devices,
and makes a bit-by-bit copy of them

hence: dd if=/dev/cdrom of=thatdisc.iso

will produce a perfect ISO filesystem image, because that's what is
exposed by /dev/cdrom

likewise for any other block device (partition or otherwise). so
creating a copy of an NTFS partition (or any fs)

# dd if=/dev/sdb3 of=partition.img
# mount -o loop,ro -t ntfs partition.img /mnt/tmp

would copy that ntfs partition, and then mount that filestem image
localy, read-only, under /mnt/tmp  (useful for forensics).

also worth looking into, is dd_rescue, which will copy (to the best of
its ability) raw partitions on a damaged drive.
