Searched through the net for about 3h now, tested anything that seemed promising - but still no 3TB! And I don't mean no 3TB partition - the drive is actually detected as 1.8TB by various programs!

And of course, Windows Diskmanagement shows also 1.863,04GB for this disk, although it is GPT formatted and has no partitions on it.
My System is a Windows 7 x64 on an ASUS Maximus V Formula with the UEFI-BIOS from 11/09/2012 v1408 (up-to-date). The disk is connected to one of the 6g Sata3 ports and has no jumpers set.
After all I've read, I would say this should work - but it doesn't.
What the heck is wrong?!
