Just got a USB key; put it in..
there was already a USB mounted (/dev/mmcblk0p4) and the new USB device not showing.
reboot
new device now showing in device manager
attempt to 'initilaize' the device; 1 partition ext4
error - 'partition failed'
so 2 questions really.
1. why was there already a USB device when there was no physical device
and
2. how to set up the new USB key
