Re: Clone a bootable USB key

[Dieder Vervoort <linuxx@telenet.be>]

Hi Adrian,

Indeed this is working. ( Test it with 2 identical USB-keys)
But I think this is not a solution because the target usb is not the 
same size and make.
Thats why I copied the files and the MBR separately.( forgot to mention 
this )

What I am trying to do: I would like to make a copy of my USB-key to one 
or more  files,
send the files to a friend and he has to dd / copy this file to his 
USB-Key, and I was hoping this should work.

Thanks,
