BIOS not seeing replaced HD

I have the Rampage III Formula (LGA1366) motherboard.  I wanted a larger secondary HD so I could boot to a Acronis boot disk and place the backup image on the new drive which is a 3 terabyte.  I already had a 1 terabyte as the second HD.  I replace the second drive with the 3 terabyte.  When I reboot the BIOS does not see the drive.  When I get into windows I have to go to device manager and scan for hardware changes under disk drives to get windows to see the drive.  I did do the disk management,  format etc and had no problems getting windows to see it but it does have to be found after a reboot like I mentioned above.  

I updated the BIOS from ASUS but it still does not see the drive.  If the BIOS does not see it Acronis will not see it so I can't pick the 3 terabyte drive to put the image. Running WIN10 64bit Pro

Any help is appreciated.

If you want to use Acronis as described on this board you'll need a 2TB drive or smaller (<2.2TB) as the BIOS can recognise but not enumerate drives with a larger capacity.  Windows can handle them but not the boot environment that Acronis needs.
The last BIOS update for the Rampage II was in 2011 and doesn't address this.

EDIT:  Ditto for the Rampage III (sorry need my eyes checked!!) that will support 3TB but only in UEFI which isn't going to help you either - go for a 2TB HDD  instead of 3

What BIOS are you working with? Have you tried connecting the drive to different SATA ports?

The latest version from ASUS for my MB.  I really don't have another place to try it unless I disconnect the CD drive.

Then disconnect CD-ROM and connect it to that port. Go to BIOS and check in all setting menus of you see the drive. If Windows sees the drive then BIOS sees it for sure.

If that works then it can't stand to see anything but the original HD that was there before?

So what is the solution? If WINDOWS SEES the drive, then BIOS sees it as well. And what MASQ wrote is not true. If BIOS fails to work with this drive then Windows will never see it as well.
Acronis boot environment based on WinPE will see this drive as well. 3TB drives are not new.

I am going to get the exact same brand but a 2TB.  I will update as to what happens when I install.  Will be here on Friday from Amazon.

Maybe you need a newer motherboard.

Put in a 2TB,  no change.  Put back original 1TB and BIOS does not see it but windows does.  So yeah maybe time for new MB

Reset BIOS to "Default Settings", f10, save and restart?
