External Hard Drive Issue

Recently my imac began to "eject" one of my external hard drives on its own. The external drive is a WD 3.0 TB drive. I plugged it back in and it showed up as normal. The next day it disappeared and does not show up anywhere.

I have a device that I have used to recover items off of other drives that have become un-accessable. So when I hook it up it says my computer cannot read the drive on the computer. It does show up in disk utility. It shows as uninitialized with 0 space remaining on the drive. This is the second drive to do this on a mac for me. I know it was initially formatted correctly. Will one of the software recovery programs work with this issue or should I just go to a professional place to try and recover? Is there anything else I can try on my end?

Thanks in advance.
 
Sorry to inform you but the 3 & 4 TB versions of the WD external have low reliability and a high return / failure rate. Strangely the 1 & 2 TB versions are far more reliable.
