Ummm yes when you dump crap to a raw device, and then you cat it you
get what you put there, and any other crap that was uninitialized after
it.

I suspect you want to do something like mkfs /dev/ram0 ; mount /dev/ram0 /mnt/ram; 
copy file /dev/ram or similar... or maybe I'm missing something.

Oh if you really wanted to do that \0 is null, echo might need
an option like -n or similar to send literals.
