We're talking about compact flash, right? IME, they've just got a vfat filesystem on them. You can just mount them directly and use tar. It's not exactly what you asked for (an image), but it should work just fine. Otherwise, to create an image, you could just cat them around. Insert (but don't mount) the source, cat /dev/sda1 > cf.img . Then put in the other one, and cat cf.img > /dev/sda1 . That should work. The only reason I suggest that instead of giving a proper dd command line is that I don't know precisely what block size to give to dd. Unless you have some very special requirement, though, I'd say the best way to move the data around is to mount it and deal with the files, not trying to mess around with images. As a test, if you do cat /dev/sda1 to a file, you could see if you can mount it the image file via -o loop, before catting it out onto the target card. good times, Vineet -- http://www.doorstop.net/ -- http://www.digitalconsumer.org/ Protecting fair-use rights in the digital world
