WD live wont read external drive.... help

i bought a WD TV Live about 4 days ago, i tried to hook it up yesterday to my 4 tarabyte external drive and the WD only reads 1 tarebyte. does anyone have any ideas as to how i can make it read the others? or why it wont read the others?

Welcome to the forums.

What brand and model is your 4TB drive?  I ask because I am not aware of any one making a single 4TB drive.

Sounds like the external drive you have is a RAID drive.   The WD TV Live should read up to a single 2 TB drive.  However, it probably won’t correctly read an external RAID drive.
