I don’t fucking know why I can’t eject USB hard drives. I installed the SysInternals apps, and best they can tell me is that Dropbox is fucking with the drives. I explicitly told Dropbox to not fuck with USB drives. I don’t know who’s lying, I just want whoever is fucking with the drives to stop fucking with the drives, OK??? OK.
The best bit is that if you lose patience and cancel, the “Cancelling…” takes even longer than finishing the job would have done. I really have no idea what’s going on. Journalling file systems in Linux don’t have to do this.
