start with
	disk/fdisk -p /dev/sd??/data
	disk/prep -p /dev/sd??/plan9
	dd -count 1 /dev/sd??/plan9 -count 1 | md5sum
	dd -if plan9 -count 1 | strings
	> should see something like
	       3: Plan9.00
	      43: CYLINDRICALFAT16
	     438: Bad format or I/O error
	     463: Press a key to reboot...
 	    488: 9LOAD
 	    500: PBS2...

you may need to open a new window to do this.
