Windows 10: How to repair a damaged partition on a data drive?

My main desktop (running Windows 10 version 2004 19041.685) computer has a StarTech hotswap trayless rack that I've used for years:



I have a number of bare hard drives that I use to backup and to store offline data; I put one of my offline data drives in which I'd used a month or so ago and something appears to be wrong and the partition must be damaged in some way because Windows says it's "5588.90 GB RAW Healthy (Basic Data Partition)":



I've tested the drive using the Western Digital Diagnostics and it passes both the SMART and short DST tests and the drive does not appear to have any problems but there's no partition data. Is there any way to repair or recover the damaged partition and files? I've googled but almost all results are about a "Recovery Partition".

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
