Sorry, I will disappoint you but CCxx firmware generation was already there.
And unfortunately, freshly bought HDD with CC1H means only "already updated" from CC1G buggy firmware, probably no more.
Because it seems there are 2 buggy firmware present on market : SD17 and CC1G.
Take a look at this post :
ll the ones I have (21 in total) have had the buggy firmware (either SD17 or CC1G). After upgrading all of them to the fixed firmware (SD1A or CC1H) all troubles seemed to have gone.
So do not expect any PCB changes or "new new" firmware. In my opinion, best hopes are now with 7200.12 generation (even is power consumption was a little increased with first 500Gb 7200.12 disk released from Seagate).
But you experience is very welcome.
