Dell L702X laptop Windows 7 64 bit all drivers up to date according to Dell.
Using 3TB as external USB drive when I plugged it in and went Disk Management it only showed 746GB.
I formatted and unallocated several times but no difference. Used Gparted per instructions no difference.
WD Partition software will not recognize the drive.
I use several 2TB WD drives with no trouble.
I have the latest Intel Rapid Storage Technologies and it does not see the drive at all.
