Have you tried disabling all drive-related power saving options in System Preferences?

If that doesn't work, I would also try disabling the sudden motion sensor (I know you say it isn't getting bumped, however, OS X isn't expecting ANY motion reporting from the optical SATA channel, so maybe it gets confused)

In Terminal, you can disable the Sudden Motion Sensor by typing sudo pmset -a sms 0 and pressing Return (changing the setting to a zero disables the module).

Edit: I'm not suggesting this is going to fix the problem, but we can see if it changes the behavior, which will help isolate the problem.
