I have been batting with this issue for a bit and cannot find the answer to it.

So the Dmesg see's the device, being Symwave WDC WD64....

media@Media-pc:~$ dmesg | tail -n 20

It looks like it attaches sdd and sde. Now when i look in the disk utility it shows "Hard disk Symwave WD6400AAKS-0 device /dev/sdc doesn't show any other info then that, if i format, it says that it cannot open /dev/sdc no device or address error.

Underneeth the device it does show two general usb3.0 CRW that are sdd and sde.

Now if I do a fdisk -l it doesn't show the device:

media@Media-pc:~$ sudo fdisk -l

So now I am confused. Any ideas how I get fdisk to see the device?
