cloning /dev/sda1

[Lenny]

Hi All,
I found that ntfsclone is already there.
I am using /dev/sdc1, another 4GB SD card to try to make another copy of 
/dev/sda1.
I am not wanting to make a file, but just copy all the files over to the SD 
card.
I mounted /dev/sdc1 as /mnt.
I try:
ntfsclone /dev/sda1 /mnt
and that does not work.
Any suggestions?
All the web pages I read on this gets quite convoluted, and if it takes more 
than one or two CLI commands, I would prefer a GUI interface to do this.
Thanks for any help.
Glenn
