4TB only seen as 1.6TB


hello,

i have installed windows 2012 datacenter test on 2tb has installed no issues.  have installed 4tb hard drive on sata port 2 bios level seen.  when login windows , server manager or computer manager shows drive @ 1.6tb instead of 4tb.  have taken same drive , put windows 7 machine , have no problems detecting drive @ 4tb. 

from server manager in 2012 have added drive 1.6tb not expand either max. 

from testing windows 7 when select drive when initialized creates 1.6tb partition , creates 2tb partition when move drive 2012 sees 1.6 not 2tb either.

not sure if missing something, please help.

thanks
