Thanks Kevin, This is quite helpful, only I have a fairly unusual disk structure, since the disk was originally a dual boot system with windows XP which I eventually converted into a full ufs drive. So all the BSD partitions are located on what was originally the second half of the disk. Is there anyway I can escape out of the automount prompt and run fdisk, or anything. I've been trying everything I can think of. Thanks, Dan.
