Wouldn't using dd only allow this img to be copied to another cf card of the same size?

the "to" device can be the same or larger.  it makes the larger device look
the same size as the original, however, so you can't simply use the
additional space for anything.

so far as i know, df in both the *bsd and GNU varieties just reports a list of the filesystems mounted and their size, usage, and mount points. in my mind df stands for "disk free" (space) and so far as i know no version supports arguments that make it work like dd.

Matt,

I have done this using the df utility. You can block copy the entire flash
disk on a machine with a CF reader. I copied it to an image on my hard disk drive. Then, you can use df to copy it back to other CF cards as many times
as you like.

Basic syntax is:
 df if=/dev/<CF reader device> of=./voyage_0.5.2_image.img

Regards,

Bruce.

Bruce,

perhaps dd (not df)
