so, i'm back! with all my data!!!
as i'm not too technical, i used 3rd party recovery software for complete scan of my HDD, it found my partition and one more which i had to delete to be able to recovery good one...
it took aprox 16h to scan, 16 more to make image file to another hdd before i make more stupid actions, after successful recovery it took again 20 and some hour to copy data from one hdd to the other (both attached by usb)... i think avira made the process slower this time...
i also copied all of my data from lap-top to the same hdd and now i'll try again to copy all that to the unRAID attached hdd... this was the point where i screwed with attaching data hdd to array... as Joe L. said:
"Never assign ANY disk to unRAID unless it is ready to be re-used/re-partitioned/formatted."
Thanks Joe, thanks lionelhutz!
