Messed up setup of new WD Elements external drive, help

[silverlakerCA]

Hi there.
I formatted a new 14TB Elements drive, and allowed Time Machine to back up to it (setting 7TB as the maximum).
That went fine.

Then launched Chronosync with hopes of backing up my Lightroom images to the Element but it won't work at all.
Is that because there's Time Machine on the Elements now?

I sure could use help.
Thank you.

Could be because of how the drive is formatted. What I'd do before copying anything is to format the drive again as APFS, make two volumes—one for TM and one for Chronosync. Then, set the TM partition up as necessary in System Preferences (System Settings), and do the same with Chronocync. Keep in mind, I've never used Chronosync, and I have no clue how it works, but this could be a solution to your issue.
