Trying to retrieve / revive external WD drive

I have a not-so-old WD external partitioned drive that was being used for Time Machine backups & holding older files on the other partition. During the last Time Machine backup it didn't complete and just kept spinning its wheels. I cancelled the backup. I'm now unable to get it to completely mount - Time Machine side won't mount. Ive tried Disk Drill app with no luck - wouldn't mount either. Is there anything I can try using macOS to make it mount & access data? I also have this from latest disk utility first aid session: I'm pretty sure it's formatted macOS journaled. I'd like to be able to use the drive for other purposes if not too big of risk of failing again if it can be repaired. But without know what the issue is - not sure what to do! Thanks for any help. Here's the format info: Sooo, wanted to re-format before recycling or other experiments. Looks like failure?? And finally , then tried first aid again.
