The machine can be experiencing a hardware issue, rather complex to debug

Given the hotplug nature of SATA, what you could try is rescanning for 
the optical unit. I never did it before but there has to be "how-to" in 
some place (searching...). Ah, look this:

But I wouldn't do it unless there is someone in the other location (at 
least for the first tryout) just in the event something fails.
