Hi All,

I am fairly certain that this disk is failing in my server, and I am replacing it straight away anyway.

However, I'd appreciate the views of the list just to be sure as I value your opinion(s).

I got these errors, once only so far, in /var/log/messages. This disk has / on it.

I am also getting these errors every 30 minutes:
