Scan the partition using getdataback, and if it sees the files, register the tool so you can copy them to another location.
Can you provide a screenshot?  Is the partition active?  If not, then try to activate it then format it.

- In the Search box, type diskmgmt.msc and then click the diskmgmt.msc
- Right-click on the partition you want to mark as Active and select Mark Partition as Active.
- Read the warning and click Yes to confirm your alteration.
- Right-click on the partiton then format.

Partition can be shown either empty or it can be shown as unpartitioned space. What exactly is your situation?
If it is just an empty partition then use GetDataBack as recommended.
If it is unpartitioned free space then use UndeletePartition from Active Disk.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I ended up wiping and reloading the server server. All is good now.
