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.

Writes are asynchronous on Linux.

Unless I mount it with sync, which I wish would be default for non-system drives (which are going to be in fstab anyway). I didn't notice any difference, aside from the lack of guessing when the magic is over. 2GiB goes into black hole, now what?

You can also use the sync command to flush cached writes and wait for completion, but I agree that it is a bit cumbersome.

Strongly disagreed. A lot of removable storage benefits very strongly from async writes. The performance benefits are night-and-day and worth the hassle of explicitly unmounting.

I think a better compromise would be to mount non-journaled + removable storage (e.g. vfat USB keys) as sync.
