Koganam, would you read my post carefully, you would see, than I didin't ask “why there is a data corruption when power failure occurs”, but looked for a better recovery procedure than reloading historical data from NinjaTrader server. And I really don't understand why should I reload historical data for 8 days, when Ninja collects only tick data and creates a minute data based on incoming ticks.
Believe me, I know a little about operating systems, teaching a course "Operating Systems Principles" in the past in a college and being a software engineer.
In previous post I wrote that deleting the last, corrupted files saves remaining data, but I was wrong.
Therefore I continue to complain about an inadequate recovery from such case.

I get your point: apparently I must have misunderstood the thrust of your post.
