I can no longer access my d drive after re-installing windows 10 on my c drive.

Thank you in advance for your help.

I reinstalled Windows 10 on my desktop computer.  I have two hard drives in my computer.  Windows was re-installed in my c drive where it has always lived.  But now, I can no longer access my d drive.  The d drive was working perfect before re-installing windows and I do have data on it that I would like to keep / retrieve.  Windows explorer does not show d drive at all.

The hard drive is a Hitachi HUA722020ALA331.  It is a 2 TB hard drive.

Here's what I've tried:

When I go to disk manager, it immediately tells me that I need to inititialize the disk before logical disk manager can access it.  I have tried to initialize it using both MBR and GPT but either option gives me a message from the Virtual Disk Manager saying the device is not ready.  In disk manager it also shows the drive with a red arrow, unknown, not initialized and with no information.

When i go to diskpart it will show the drive being online but also shows it with a size of 0 B.  It also tells me that the drive is readonly and when i type in the command "attributes disk clear readonly"  diskpart fails to clear readonly.

I have also uninstalled and re-installed the drive.  Checked updates for drivers.  It has most current driver.  

I have also tried using data recovery software from stellar and easeus and neither of them show the drive.

I also took out the hard drive and connected it to a Nexstar and connected it via usb to my laptop when i couldn't get working as an internal drive to my desktop.  Tried all the above and still the same.  I also made sure to run as administrator.

I don't know what else to try.  Please help.

Thanks!
