    I accidentally unplugged my Time Machine backup hard drive today without ejecting it first :-/ It had successfully finished making a backup a couple of minutes before this happened and so I hope that this hasn’t corrupted the drive. I checked to see if I could retrieve files from my backups and seem to be able to do that without an issue.

    I then ran the “tmutil compare” and “tmutil compare -s” commands via Terminal to verify the backups. To my surprise (and mild horror!) I got the following results: “Added: 80.7K Removed: 47.9M Changed: 199.9M” I expected these to be around 0 as I had run the commands right after running a backup and without making any changes to the files on the Mac. I disabled WiFi for good measure too. The majority of the changes seem to come from one file “! 148.4M (size) /Users/username/Library/Application Support/Google/Drive/user_default/sync_log.log”

    Is my drive in good health or should I be concerned? What would you guys recommend I do next? Many thanks!

    If it was done with the backup when you did this, I would not worry too much about it and the odds of there being any issues are low. Maybe run a Disk Util first aid on the external just for good measure.
