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: Resetting SATA devices under Linux http://www.skytale.net/blog/archives/24-Resetting-SATA-devices-under-Linux.html 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.
