e2fsck /dev/sda1 reports clean, and it looks like smartctl is not present.

I agree, smartctl should be on the live image. I know the idea is to keep the ISO size down but it makes the live media useless as a diagnostic utility so I usually end up keeping System Rescue CD on a old 1GB usb stick for real diagnostic work or when I'm upgrading drives and need it to move everything over.
