This is what I have:

# smartctl --all /dev/sda

Device does not support SMART

Error Counter logging not supported
Device does not support Self Test logging

I guess I am stuck since it says it doesn’t support SMART.  Or is there some way to get some status from this “disk” to see if it’s really the root cause of my performance issues.  I think I would have seen something in /var/log/messages if there was a critical issue.
