installed a 256 SSD in the main drive bay and replaced a 750 7200 drive that was in the optical bay (running fine for ages) with a 750 Momentus XT. Before switching the drives in the optical bay i did a clone of the 750/7200 to the 750 MXT... looks fine through USB as an external drive. When i switched the optical bay drives i had a problem. Machine booted very slowly, comes to the desktop but the cursor (trackpad) is non responsive as well as the keyboard. An external mouse works but only to move the cursor. The desktop and icons do not react to click or drag. Machine is essentially frozen. Removed the drive, works fine. Re installed old drive in the optical bay, works fine. MXT shows up and works well through USB as an external but no dice on the connection through the optical bay Any idea's? Searching here and google didn't find anyone with this specific issue. mbp 2.2 i7 2011 running Lion w/ latest updates. Any insight is appreciated, thank you in advance.
