USB drive from another windows server backup is inaccessable on a new server

Just pulled a Vantec 2Tb USB drive off the shelf to use for a backup drive on a physical server.  Its' previous application was as a Windows Server Backup drive on a Windows 2008R2 server.  The new application is also 2008R2.  The drive was not "decommissioned" after the backups on the old server were no longer relevant.  That server got virtualized.

When I run Windows Server Backup, the USB drive does not show under available targets for my backup.

The USB drive shows up in File Manager, but prompted me to format before it could be used.  I did a quick format - show Properties comes back with the full drive capacity unused, Security shows full control for SYSTEM and Administrators, but I notice no rights are selected for Owner/Creator and access is denied when I attempt to edit logged in as Administrator.

A couple things that shouldn't matter.  I say the drive is inaccessible on a new server.  Turns out that it's actually the same physical server.  It is, however, a clean installation of Windows Server 2008R2, different host name and different roles.  The USB 3.0 drive is connected with a 2.0 cable.  The 3.0 cable appears to be have been misplaced.  I think the only penalty here is speed.

Connect the drive - go to Windows Disk Management (right click on My Computer - Manage - Disk Management).
Delete the current partition from this drive.
Then right click on the free space - create new partition. Follow the wizard and select NTFS - quick format.
After that see if you can use the drive for backup.

OK I follow up to the point where I have Disk Management screen up.  The top "Volume List" does not show this device.  It does show up in the lower "Graphical View" as Basic and Online.  Delete Partition is not an option I see, but Delete Volume is, as well as Mark Partition Active.

Take a screenshot of Windows Disk Management and post it here. Looks like the drive is dynamic somehow. That could explain why you cannot select it for backup.

Guess I didn't refresh before I accepted the solution...  I didn't notice your request for a screen shot.

After deleting the volume and creating a new volume and doing a quick format, this disk, as F: showed up in both views in Disk Management (instead of just the Graphical View).    It still shows as Simple/Basic/NTFS.

As it turns out, there is still an issue.  Now I have more failure modes.  Depends on how I configure Server Backup.  If I Schedule Backup, it all looks normal, except perhaps where I pick the target hard drive.  The USB drive shows as Disk4 and when I ask for additional details, it does not include volume F:  I select Disk4 and get the warning that the target disk is to be formatted.   A few minutes later, I got an error telling me the format failed.  I tried this a second time and the MMC snap-in unloaded after a "non-valid operation."
When I Backup Once, the F: still does not appear at the point I select a target for the backup.

Is the drive new and functioning well when you use it in Windows for data only?
Does it have its own power supply?

I tried a second external USB device - same issues.  After deleting the existing volume and creating/formatting a new one (both had been used for Windows Server Backup), they both worked fine with file copy/paste/open/delete operations.  The first device had an external power supply, the second did not.

FYI, looking for issues in Device Manager, I found that there was no driver for the add-in USB 3.0 card installed in this server.  Any successful connection has been through USB2.0  ports.  Am looking for that driver.  Would certainly rather have this using USB3.0.

I'm getting close to just installing an agent on this physical server and backing it up with my VM environment...  This is a temporary server and didn't see an advantage in doing that initially.

Thats correct. Windows Server Backup is not perfect and should be used if third backup tool is a no go only.
Anyway with USB2.0 and external power supply it shoud work. As an example you can try taking backup to network share or internal drive. Maybe proble is in WSB and not in HDD.
