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.

Even better. I'm definitely going to use 'sync' when I unmount a removable drive. Thanks.
