By this you mean, you used ccd to reformat the drive as part of a newly 
created RAID-1 mirror?

If you just newfs'ed the disk, most of the data blocks will still be 
intact and can be recovered (to some extent).  However, if you did 
create a RAID filesystem on the disk, you are out of luck.  The process 
of creating a RAID-1 or -5 volume involves syncronizing all of the 
disks, which will overwrite every sector on the drive.

I'm sorry that you lost data.
