Hello,

I was able last night to gather some more info about the OS and the condition of the disk. I think it needs to be replaced. As you will see from below is the alternate disk and not primary. I'm trying to scramble a procedure for replacement from "When Good Disks Go Bad" but i have some doubts about it. If you can help it will be real helpfully.

Any help will be great,

Thank you.
