Time Machine Buddy says: Stopping Backupd to eject destination disk!

Question

I have a new external hard drive to replace one that failed for Time Machine BAck up.  I formatted it and two nights ago,  did a successful initial backup which consisted of about 600 or 700 GB (on a 2TB drive) .
Last night,  I checked on Time Machine and saw it was "preparing to backup "  for 1 1/2 hours.  I knew that was not normal so opened up Disk Utility to verify disk.  However,  Disk Utility just hanged.
The color wheel just started spinning and everything on my screen was frozen,  so I powered it down.  After two attempts to power back up,  the computer finally came back up,  but now my new external hard drive is not recognized by either Time Machine nor Disk Utility.  I tried powering down the drive,  disconnected it from the computer,  then restarted the computer twice,  and the drive was then recognized
I was then able to do a successful backup last night.
However,  this morning,  on reviewing Time Machine Buddy, the last line after BAck up completed successfully is :” Stopping backupd to allow ejection of destination disk!”
How did this come about and what am I doing wrong,  and how can I fix it?
I am also using Time Machine Editor and have only scheduled backups twice a day.  Could this be the problem?  Although I have used these two programs before with my other USB external hard drive (™ Editor and ™ Buddy ) without any problems.
I am posting a copy of Time Machine Buddy’s status.
I would appreciate any help ,  thank you!
P.S. It looks like my external hard drive is ejected?  but Time Machine and Disk Utility still have it listed.  I tried verify disk again this morning,  but it just hanged like the other night.

THANK you,  Klaus.  Did you send me the link to pondini?  Somehow I do not see it here,  but got it in my email notification?
Did you say "late"  Pondini?  So sorry to hear that!
I have searched his website but did not see anything relevant to why my destination disk is getting ejected?
I wonder if I should just disable TM Editor?  Same thing that happened originally,  again happened this am with my computer freezing,  having to power down,  etc.
Anyway,  thank you for your interest.
