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.
You can also just pull the USB drive out, if you have waited a reasonable time after last writing to it, no harm will be done.
Also, terminal commands have the advantage that they are the same over the course of 20something years and across all desktop environments, while the tinyfloppy windows moves critical functions around with every second patch so you have to relocate stuff you had just memorized.
And if you’re not sure whether the cache has been fully flushed, run
syncand it’ll return once it’s done!
