no luck seems that quick wipe deletes 1mb data at the begining and 1mb at the end of the disk.
so i think i cant do nothing to do at this point to try to recover some data from my raidz pool.

Yeah.. i'm 99% sure there is no recovery.

i dont understand how 1mb of data can do that damage to 3tb disk.:(

Why not? If the 1MB that is overwritten is the crucial information that proves data is even on the pool, then yes, overwritting it would cause you to lose everything.
