Neither of the MBs that I am using for testing are even capable of UEFI. all are MBR.
My main MB is a Gigabyte GA-Z87-D3HP which is capable, but I have Win 7 Pro installed (which is NOT).
I did download an iso of build 9879 and installed on the one system:
-C: is WDC SATA2 WD2500KS 250 GB and then added 2 of the ST1000DM003s that I have been having trouble with for D: and E:
I also added 2 of the drives to my other installation (which has been upgraded from the original).
Couple of them were in the state where they would not spin up, docking into the linux system and reseting that PUIS feature to off, inserting into the Windows 7 machine and allowing Scan & fix when requested got them working.
Not had any issues so far today, it's almost like something got 'fixed' in the build without anybody saying anything!
I am ABSOLUTELY convinced that Build 9879 has been the culprit because I have been using these drives for months in a Win 8.1 Pro system (1 drive), a Win 7 Pro system (2 drives) and one in my main Win 7 Pro system that has been in-service without a hiccup since I bought the parts (1 Feb 14), assembled and brought the system up. In fact I have NEVER had any issues with any previous Seagate drive of the same family (ST500DM002 & ST1000DM003, 500 & 1000 GB) & I have multiples of each of these drives. The main reason that I have the 1000GB drives is that you can't find the 500's any more.
I did verify with one of the problem drives yesterday that with that PUIS feature enabled, the drive does not even spin up. It needs to be inserted in a Linux system and have that feature turned off. NOTE that the Linux system has NO problems bringing up and communicating with the drive that has that feature turned on - In the SAME system, simply shut down, swap main drive to a Linux distro and booting up.
It's starting to make me wonder what the Linux community knows about this feature that the MS Windows programmers don't!
