This was a flag that the WD utility program was the issue. Seagate is the only company Ill never buy from again - way too many second chances given to their hard drives. I do have a Lacie (regular hard drive, not SSD) as my Time Machine backup and its been great.

When automatically updating for the Sierra 10.12.2 update, an App Store notification window appeared stating “WDDriveUtilityHelper prevented updates being installed”. Sandisk, G-Tech, and Samsung are the brands Id feel most comfortable with.

After a few hours, I could not access My Book with Finder (no Backups.backupdb folder).

Determined the issue was not with Time Machine as I turned backups off, rebooted the iMac, confirmed with Finder that I could read from My Book (Backups.backupdb folder was visible and accessible).Library/LaunchDaemons/ (this starts the WD Drive utility helper).įrom the System Preferences>Users & Groups>Login Items, remove WDDriveUtilityHelper (this runs the helper when a user logs in).Īfter performing these actions, My Book has successfully executed Time Machine backups for 2 days with no issues. Additionally, I deleted the following that were not removed by the uninstall program:

There is an uninstall icon in /Applications for this. Update: I have resolved the back-up issue by uninstalling the WD Utilities program and removing other items associated with this program.
