I purchased a 3TB drive last year and it was partitioned in firmware to 
1.5TB partitions.  I just purchased two 4TB drives and they are firmware 
partitioned into a 1.8TB and 2.2TB partitions as I just checked.

Putting the drive into a USB drive holder, I see two drives appear in 
dmesg with the new 4TB drives.

[520426.457278]  sdf: unknown partition table
[520426.465781]  sde: unknown partition table

I had to use a firmware tool from the manufacturer to convert the drives 
to a single partition with the 3TB drive.  I have not tried the 4TB 
drive yet.

As my drives were from seagate, I just downloaded their tool and used 
it.  I had to put the drives onto a SATA buss to do the conversion as 
the software wouldn't work through the USB port.

This may be your problem.
