Before reading this forum, I'd never heard or considered updating hard drive firmware. I really don't have a grasp on it at all still. I am moving around the four HDs in my Mac Pro for optimal performance (the biggest, slowest drive is currently my boot drive - I know, stupid me) and I'm wondering now if I need to update my firmware or if I'm just making stuff up in my head. My HDs are as follows, in case: Western Digital WD3200AAJS-41VWA1 (original boot drive from '08, now will just house my downloads folder) Seagate Barracuda 7200.12 ST31000528AS (going to be my new boot drive - am I picking the right one?) Seagate Barracuda 7200.11 ST31000333AS (gonna house my iTunes folder) Western Digital Caviar Green WD20EARS-00S8B1 (was stupidly my boot drive, going to create 2 partitions and back up boot on one, music on other) I'm just going to setup the backup daily through Carbon Copy Cloner. Am I going about this correctly? Oh yeah, and original question - firmware? You guys have been awesome to me so far, thanks!
