Hi !

I have add a new disk to my sparc 10, with Solaris 8.

I have mounted this:

/ (/dev/dsk/c0t0d0s0 ): 31064 blocks 20857 files
/usr (/dev/dsk/c0t0d0s6 ): 172902 blocks 192672 files
/proc (/proc ): 0 blocks 932 files
/dev/fd (fd ): 0 blocks 0 files
/etc/mnttab (mnttab ): 0 blocks 0 files
/var (/dev/dsk/c0t1d0s6 ): 554710 blocks 161273 files
/var/run (swap ): 310560 blocks 9609 files
/tmp (swap ): 310560 blocks 9609 files
/opt (/dev/dsk/c0t0d0s5 ): 47564 blocks 13368 files
/export/home (/dev/dsk/c0t0d0s7 ): 1302516 blocks 253743 files
/usr/openwin (/dev/dsk/c0t0d0s1 ): 167084 blocks 116062 files

But i get error when i reboot.

** /dev/rdsk/c0t1d0s0
BAD SUPER BLOCK: MAGIC NUMBER WRONG
USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
eg. fsck [-F ufs] -o b=# [special ...]
where # is the alternate super block. SEE fsck_ufs(1M).

If try to run fsck -F ufs /dev/rdsk/c0t1d0s0 i still get magic number wrong.

Any sugestion, for my problem "please" ?
