Yes, because they might not be _completely_ erased - unless they have a cleanmarker node at the beginning, then it's possible that they're only partly-erased. So it erases them again, just to make sure. > I also noticed that an umount hangs until kupdate is finished, should it? There's no real reason for it to do so - can you get a backtrace (SysRq-T) and find out what it's waiting for? That should be fixable. > Is it safe to power cycle the board during this initial formating? Yes. The formatting is done specifically to make sure it's safe to power cycle at any time. -- dwmw2
