Thanks for the numerous replies with most stating to run fsck -F ufs -o b=32
c1t0d0s2. Which worked!

Original Question:

I have a E420 server with Solaris 8 and I get the following message after
bootup. The system appears to be running fine except for one disk used for
storage which we get the following message.
Disk 2 cannot read; block 16, unexpected inconsistency. Bad Superblock magic
# wrong use alternate superblock to supply information (c1t0d0s2). We tried
running a newfs on the disk and also ran a newfs -Nv c1t0d0s2 for Superblock
info and get kicked out with the message "cannot read block 16" before it
completes. Any sugestions on fixing this other then replacing it?
