newfs -N /dev/rdsk/c0t0d0s0可以看到所有的超级块，前面的不行，可以用别的。

你的盘是用veritas管理的，能这样修坏块吗？

硬盘有块(不是super block)损坏,用format去恢复.

为什么现在都要搞特殊置顶呢

BAD SUPER BLOCK: BAD VALUES IN SUPER BLOCK

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).

format 命令来修复是否太危险了,具体应该怎么拿来修改呢?

这是一个例子,你用"y"带替"n" 可以继续进行修复.
