I'm having difficulty finding out which version of the firmware is on my XT750. I've installed Win7 under Parallels and ran the Seagate utility. It returns, F.MSZ3Q4, but I have no idea what that means. Whenever I click on the MomentusXT link at Seagate, I'm taken to firmware for the 250GB, 320GB and 500GB drives, no mention of the 750GB. Can anybody point me in the right direction?
