I followed the instructions from the previous post, using fdisk, set it 
to b wrote it, then did the mkfs.vfat to format it.

Rebooted the pi, /dev/sda1 was mounted as /media/pi, and the ext4 
partition /dev/sda3 was mounted to /media/pi/_1.

But I ran into an rsync problem when I wanted to --exclude=/boot, it only 
sent 49 bytes the first time, and only  40 bytes on try two.  So I 
removed the --exclude, and its now copying / to /media/pi/_1/ at a 
pretty decent speed for a pi with its usb2 speed limit to anything.

Once this has finished, I have a reader ready to plug in, with an even 
faster 32Gb sd in it and I make probably the 20th attempt to use piclone 
to make a backup sd card as I and another coder have about 6 weeks worth 
of work we do not want to lose if this sd card goes tits down.  The 
kernel being used for the previous tries had very short uptimes, and 
piclone never got to the finish line.

Amanda has backed it up, so I have that as a last resort, but I want at 
least 2 bare metal backups to protect the ground breaking work of 
putting a pi to work running heavy metal via LinuxCNC in real time.

Oh fudge, rsync is in a recursive loop. Damn.
