Yes i know about it, but it recognizes as:
ls -la /dev/da0*
crw-r-----  1 root  operator    0,  77 Apr 28 17:23 /dev/da0
crw-r-----  1 root  operator    0,  80 Apr 28 17:23 /dev/da0s1
crw-r-----  1 root  operator    0,  93 Apr 28 17:23 /dev/da0s1c

and

#gpt show da0
        start        size  index  contents
            0           1         MBR
            1          62
           63     3571210      1  MBR part 165
      3571273  8589937079


but there was a 4TB slice with important data, i didn`t touch RAID - so 
it`s should be there...

i didn`t remeber was it gpt or not :(

And yes hdd failed during reboot so RAID filesystem should be clean.
