Synchronization problem

Desktop

Hello,
I just installed Owncloud on my Mac mini M4 Pro and I’d like to add my server address.
So I entered my server address, then my login credentials. When I get to the synchronization page, I want to add my SSD, which I’d like to back up. I go to the advanced settings to select my SSD. I then click “Finish,” but at the end I get this message!

I do not understand French - but I assume the error message is stating that the file system is not supported - right?

What filesystem was your SSD formatted with?

Thank you for your reply. Indeed, the hard drive wasn’t formatted correctly. I formatted it as APFS and it works.
