My SCO Unix server was shut down during a power outage. Now when I try to boot back up, it says:

Root file system needs check..

I press ok to check then gives this error:

Error FSCK read failure BNO
Bad sector detected

How do I fix this problem to get the server backup?

This is not good. Although I am not familiar with SCO's boot process, I know somewhat about it, and I know that bad blocks (or bad sectors) are a bad omen.

First - make sure you have a backup. You might have a damaged physical disk.
Second, try booting into single user mode (maybe append "-s" or "single" to the boot command) and try running fsck manually. You might be able to succeed.

It's still not looking good. I tried doing it in single mode but same error comes up and doesn't let me get passed it. Is there a way to bypass the bad sector until I can grab my data off there?

My only suggestion is to connect the physical disk to another SCO system. Sorry I can't be more helpful...
