At any rate, I'm now unmounting and then waiting for a while before removing the flash (just in case it is still writing). Thanks.
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.
