I had finished with the 2TB SATA so formatted it, left it on all night as it was that slow, but when I put it into the built in sata dock on top of the case the pc didnt see it. I rebooted to no effect.

I went into disk manager and told it to present a new volume on the disk, at full size and it did. But still it does not run in the SATA dock, so I put it into the external usb dock and managed to copy a couple of files across, but not vice versa on the pc dock? I dont want to install it as secondary drive until I know its working properly.

If that makes any sense. Do I need to create a primary partition too? Win 8.1 tells me that it can partition disks but I cannot see the method in the disk manager.
