Hi All, I recently purchased Carbon Copy Cloner 4, and discovered that it had the option to unmount the target drive after finishing a backup. I enabled it, but the drive does not unmount. I cannot even unmount the drive in Finder without getting a warning that the drive is in use. I have looked through the console logs, and I am not able to figure out what program is preventing the unmounting of the drive. I have the volume excluded from Spotlight, am not running any antivirus, so I am at a loss. I even re-partitioned the drive and started fresh with the clone, and it did not help. How can I find what program is preventing me from unmounting? Thanks.
