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.
It’s an ongoing PITA. Windows should come with Process Explorer installed by default.
Windows should just tell you “The file is in use by <actual information here>” by default.
You’re right, of course. I’m so beaten down I now I guess I just accept the mediocre solution.
