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. -- -Chuck
