Bootable SD Cards

d3x0r

I have the ROC-...UBUNTU... image working on 1 SD card.
I got some additional samsung cards at the time, and when I copy the image to them (dd if=theImage of=/dev/sdc ) they get the same data, if I read it back, I can diff that and the source file and it's the same....  but the samsung cards didn't boot.
I went to the store today and got another of the original type, (although it's a different lot but the same size) and they don't work, I also got different samsung and some patriot sd cards, and so far only 1 in 5 SD cards will boot.  
And, they all read exactly the same when reading /dev/sdc...
they all report as 32GB in size, but dd if=/dev/sdc of=testImage   only reads back exactly the size of the original image... how does it know?
On the one image that did boot,  added a bunch of stuff to the drive (presumably in the additional 26GB after the root image) how do I copy that to another stick if it only reads 2.4G?

If I understand you correctly, you flash a 2.4G image to a 32GB sdcard,
and read back 2.4G with the following command:

     dd if=/dev/sdc of=testImage

I'd like to confirm that first.

And would you give a photo of all your five SD cards?
