Can’t do time machine back up to my WD Passport HD after installing Big Sur ?

Just upgraded to Big Sur. Using WD HDD Passport for Mac. Three tries it just keeps saying “preparing backup” and blue line keeps moving back and forth. It DID say it recognized backup drive selected. Will appreciate all ideas/help. Thank you.

iMac, OS X 10.11

How is the Drive Formatted ?


It needs to be formatted into a format Catalina understands.


Is there any Third Party software that came Bundled with the Drive installed on the computer ?


How I is the drive connected to the computer ? Directly into the computer or through a USB Hub ?
