if there is a clear pattern like 0's or 1's then 9 is easy, for some partial data recovery. the more times you re-write and the more random the writes both in data and sizes, as the data's not exactly writen like a record any more the harder it is to recover random data gets hard to recover around 3 rewrites by ?local? places, for those that wear aluminum hats the line between ?local? places and the big guys is getting smaller and smaller each day and $billion to the national debt.
