[smartmontools-support]How to get CF card's serial number?

[zhaohaibo <zha...@ne...>]

hello,

    I'd like to get CF card's serial number in linux or freebsd.
I have tested tools:hdparm,smartmontools.
    #hdparm -i /dev/hda
    #smartctl -i /dev/hda

    F000535497, I got this number by above commands.
But I can't find this number on CF card.
    
    So I am puzzled.
    CF card's SN is same with HD's?    
    
Thanks!
