WD30EZRX a disappointment

Received 2 of these from Newegg yesterday.  BIOS sees the drive(s) perfectly.  But when wanting to use or partition them they aren’t recognized.  Very frustrating.

Motherboard is a Gigabyte GA-MA78GM-US2H

If running windows7 right click on my computer then start manager from there you can format your drives

windows 8.1 start My pc manager is last on list at top of menu

I use Linux.  Besides the installer options I’ve tried Gparted and others but none can find the drives.  Never had any problems with other WD drives.  Currently using a couple 2TB Blacks.

Looks like I may have to send these back.
