I do not thing behaviour on powerfail is part of block device definition.
Pavel, AFAIU,
Joern meant that if HDD starts a block write operation, it will
accomplish it even if power-fail happens (probably there are some
capacitors there). So, it is impossible, say, that HDD has written one
half of a sector and has not written the other half.
And he wanted to say that DataFlash HW does not guarante this. But,
perhaps, adding a special HW, this is implementable.
