Not sure if everybody else has already heard about this, but I hadn't... There's now a new firmware update out for the Seagate Momentus XT that stops some of the spin-downs and freezes etc. associated with the earlier firmware.
I just updated mine using these instructions: http://www.io101.org/blog/howto/update-seagate-momentus-xt-firmware-sd24-sd25-on-macbook-pro/
Everything seems absolutely fine and I'll be interested to see if it does result in me getting better battery life. I think the hard drive maybe sounds quieter too, but that might just be in my head!
I'll report back with any issues etc.
