this command is destructive and it will erase all data you shouldn't use it on a partition with important data # newfs

if you already have a ufs partition then there is no need to make a new file system
be careful not to use it now, as it will delete everything
anyway it's used this way:
# newfs /dev/ad8s1a
but do not run that command now!
 
Code: 
2T8# mount -t ufs /dev/ad8s1a /root/backup
mount: /dev/ad8s1a : Operation not permitted
there is problem
 
same error
Code: 
 mount -t ufs /dev/ad8s1a /mnt/backup
mount: /dev/ad8s1a : Operation not permitted
 
I see you are using GEOM on the ad4 and ad8, what are you using it for?
Besides geom, the only cause for having a permission error are that you are not root, you have already mounted something on the same target directory or there is a jail and/or a security level enabled.
 
thank you for help i have fixed thank you much!
The hard disk is repaired :D
now other question:
i can set up primary hard disk ad8 and ad4 the secondary?
