Robert,
To go from one identical sized cf card to another identical sized card,
ideally same brand, with a hard disk file in the middle, and assuming
the CF card was at /dev/hda and that the hard disk was being used as
part of /var, I would do something like put the one you want to copy
into the CF drive and:
dd /dev/hda /var/cf_images/cf_image-name.img ; this copies all the data,
including boot track, to a file called cf_image-name.img in a dir called
/var/cf_images/ that must already exist;
then swap the master for the blank in /dev/hda, and...
dd /var/cf_images/cf_image-name.img /dev/hda ; this takes the data from
the file and puts it onto a blank cf card
Note, this may take a while, if the cf drive is slow and the cf size is
large. It also does not work well if 2 different sizes of Cf card are
used. Do not get this backward, of course, or you can wind up with 2
blank CF cards, or worse, a blank hard disk !!!!!!!!!!!!!!!
Anyway, that's the way I always do it, if CF cards are the same.
Cheers,
- Michael

Hello Guys,
At the moment with all the packages I install and changes I make to
the configuration of my systems the build time is quite lengthily from
start to finish.
Is there any efficient and simple way to duplicate compact flash
cards? We’re not talking massive numbers so I want to avoid doing it
professionally, just something I can do here with my card readers
would be good. I want to be able to create one finished card and then
make multiple versions of the same thing.
I have done this a long while back but found that we has problems with
networking when placing cards in different boards, it seemed to get
confused. I forget which method I used.
I’m using grub boot loader if that makes any difference.
I look forward to getting your suggestions guys,
Robert
