"Disk Not Ejected Properly" alert appears after unplugging & plugging back in Blue Yeti mic

Every time I unplug and plug back in my Blue Yeti microphone to my Mac Studio, I get an alert saying that my WD Elements Desktop hard drive (used for Time Machine backups) was not ejected properly although I never disconnected or turned off my Elements hard drive myself. Here is what the alert says every time:

Disk Not Ejected Properly
Eject “[name of my Elements hard drive]” before disconnecting or turning it off.

It appears that unplugging & plugging back in of my Blue Yeti microphone triggers the improper ejection of my Elements hard drive, but then the disconnected external hard drive gets reconnected automatically soon after.

Is this expected? Why is this happening? Are these inadvertent disconnections & reconnections of my Elements hard drive affecting my Time Machine backups? If so, how can I fix this?

Thank you.
