Thanks to all that replied so fast. I can't believe through all the
searching I did that this didn't show up. Maybe I'm just an idiot.
Anyway, I was just forgetting to run newfs on the new disk... Thanks
again to all that replied.

Subject: bad magic number

Gurus,

Our server had a bad drive and I replaced it with a new one. It seems
to see the drive fine. I formatted and labeled it, yet whenever I try
to mount one of the partitions on the disk, it fails with the following
error message:

"/dev/dsk/c0t1d0s1: bad magic number"

This is a Solaris 9 OS. I've searched all over the place, including the
archives of your site, however, nothing has worked. If I try to run
fsck on the disk, it fails stating:

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).

I've ran fsck -F ufs -o b=# with just about every location the backup
super-blocks are, to no avail. I hope this isn't a RTFM email, my
apologies if it is, but any information given would be greatly
appreciated. Thanks!

- Alan
