Why is Windows Server 2016 not recognizing my Western Digital external USB 6TB drive, when it does recognize my external USB 1TB drive?

I have a 1TB USB external disk drive connected to my Windows Server 2016 and backing up data to it.  
Because it is only 1TB in size, I need a larger capacity USB external drive for backups.

Note:  I am using Acronis Backup 12.5.

I purchased a Western Digital 6TB USB external disk drive, formatted as NTFS (Allocation unit size:  4096 bytes)

When I plug the 6TB USB external disk drive into the Server, the drive is not recognized by the Server.

What could be the problem?

eemmpph,

Have you checked for the disk in the Disk Management Console?

It would be helpful if you could attach a screenshot of that here so we can see what's going on with the disk.

Thank you,

The Windows 7 Disk Management View for drive T: has the view below.

 However, Windows Server 2016 does not show the drive at all.

eemmpph,

When you plug it into the Windows Server 2016 machine, does anything come up?
Is it showing up in File Explorer or just not in Acronis?
Have you checked Device Manager?
And you said Disk Manager doesn't show the disk at all?
Have you tried a different USB port?
is the Server Virtualized?

Thank you,

Can you post the Disk Management snap-in screenshot from Windows Server 2016 when the drive is plugged in?

Also, can you check event logs and see if there are events occurring at the time when you're plugging the drive in?
eemmpphAuthor Commented:
It does not show up in Explorer, nor Device Manager, nor Disk Management.  

Yes, the Server is virtualized, but I am plugging the usb into the host, not the virtual machine.  

The 1TB drive appears, but not the 6TB drive.
eemmpphAuthor Commented:
I will get a "disk management view" from the Server so that you can see what I see.

eemmpph,

Nothing regarding USB devices shows up with any sort of error or warning symbol?

Have you tried downloading drivers directly from Western Digital for your device? Or did it come with any software?

Are the USB Ports 3.0?

Thanks,

if its virtual machine, what is your hypervisor, is it VMware or hyper-v

If it is hyper-v, you need to configure USB drive as pass through disk
https://thesolving.com/virtualization/how-to-configure-a-pass-through-disk-with-hyper-v/

If its VMware, you can add usb device directly connected to disk

I have a VANTEC USB case that is limited to 2TB Drives.  My 3TB Drives were not registering.

Okay, I found the problem (no driver installed).

I was mistaken when I wrote:  "It does not show up in Explorer, nor Device Manager, nor Disk Management. "

It does NOT appear in Windows Explorer, nor Disk Management".

The drive DOES appear in "Control Panel \ Device Manager", however, it has a yellow shield next to it.

When I click update driver, it says "Windows was unable to install your WD SES Device USB Device.

I went to Western Digital's website, and downloaded the 64bit driver software (which was a .msi).

After installing the driver software, the drive still had a yellow shield in Device Manager.

I disconnected the USB cable from the computer, then waited a few seconds, and reconnected the usb cable.

The WD 6TB drive now appears in:   This PC, Windows Explorer, Device Manager and Disk Management.

To answer your question, my virual machine is Microsoft Hyper-V.
MaheshArchitectCommented:
but is it appearing in virtual machine (2016 server)?
MaheshArchitectCommented:
you need to add drive as pass thru disk in VM properties
David Johnson, CD, MVPRetiredCommented:
You found and fixed the problem.. missing/bad driver
eemmpphAuthor Commented:
I looked in This PC, and Windows Explorer but did not find the USB drive.

I want to thank Devin (and give him the credit), because he suggested "Have you checked Device Manager? "  A look at Device Manager, which would have shown me the yellow shield right away (indicating a driver is missing).
