Hi Erich, As I understand things, you believe that your filesystems are okay and you just want to recreate the MBR so you can try to fsck and mount them? How did you set the disc MBR up in the first place? If you used the automatic scheme in the installer and you know the size of the disc, you could reconstruct things that way. What does `gpart show' look like at the moment? --sym
