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.
