You can if you want also run the 'sync' command to flush out the
write cache of the system.
I do that myself before I remove any type of disk that I have
written to, mainly out of habit, it's not a bad habit to
have.
I believe once a file system is unmounted all of the writes
have been flushed to it. You can see the change in behavior:
- write a bunch of data to a disk, run sync, then unmount,
it should unmount immediately
- write a bunch of data to a disk, then unmount, it may take
a few seconds(or more) to unmount.
Not sure why those popups aren't showing up on a consistent
basis, I don't use CentOS as a desktop, my Debian desktops
don't show any messages I don't think, though Ubuntu seems
to.
