Hi @Glen
Thank you for the question and welcome to the Community!
This certainly sounds like the optimized file scan database on the client has an issue and the next step is to rebuild.
Please check for the presence of registry key:
Location : HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\Instance001\Data Classification\Configuration\{GUID}\
Key Name : DatabaseRebuildControl
Type : DWORD
Value : 3
This marker governs if the database should be rebuilt on the next services restart.
Please restart all client services and you should the database get rebuilt. The database can be found in this location, but as you suggest, there will be a separate database per volume:
C:\System Volume Information\Commvault\Data Classification
The database will named something similar to “dc_002.db”.
There are also steps mentioned in documentation for manually deleting the database if this automatic process doesn’t yield results:

Thanks,
Stuart
