Hey guys, I recently got a 15" Sandy Bridge MBP (2.0 GHz), and had been researching on getting a second HDD/SSD (via OptiBay) when I realised something. My MBP came with a 500GB Seagate ST9500325ASG (5400.6) as stock. The G at the end of the model number seems to indicate that it's a G-Force-equipped drive, according to Seagate's website. Question 1: I thought there were incompatibilities with SMS and an HDD's own shock-sensor? Have these been solved? Question 2: I can't find the place where it says if the SMS feature is supported/enabled; I remember it being in System Profiler>Serial-ATA, but not any more. Using Terminal to check (with pmset) yields an "sms 1" though. Does this mean SMS still exists? Or does it now report if an HDD supports some kind of movement sensing on its own? Question 3: Would SMS stop a drive installed on the optical drive SATA connector? Thanks!
