I have a new seagate 4 tb hard drive to repace my old 320 gb for storage.
It shows up in bios but not in windows disk management. I thought maybe it was bad so i checked it in an external enclosure and was able to format and work perfectly... put back in computer and same problem!
just to make sure motherboard was ok put old drive in and works fine.
What is the problem???

With disk management you mean the thing that you use to create partitions and stuff?
Oh, also I have heard that hard drives with more than 2TB need some "special treatment" to work.
Maybe that's the reason.
I remember it as one of the reasons why I won't get a drive with more than 2TB, but I forgot what it was.

EDIT: Googled it: http://www.hgst.com/support/faqs/hard-drives-greater-2tb-may-not-work-existing-operating-systems

"This is not an internal or external hard drive issue. It is a 2TB volume limitation caused by the Master Boot Record (MBR) partitioning scheme that has long been used by Windows 32-bit operating systems such as Windows 2000 and XP."
