KDE has a "safely remove" option (just like windows!), which we are
trying
to use. But if you have written a lot (say 2-4 GB), then after a
minute or
so an error message pops up saying that it was unable to unmount,
the following processes are still accessing the drive, etc..
I understand that it is waiting to sync, but to the typical user it
looks like
an error. The problem is that the sync takes a long time, but you
have
no idea how long.
That's why I've been going to a terminal and sync-ing from there,
at least that way I know when the prompt comes back, I can go back
and "safely remove", and it will work fine at that point.
Ideally, I would be able to turn the buffering off. It might take
konq
longer to complete the "copy", but at least when it said that the
copy was complete, the copy would be complete and the unmount
wouldn't time out.
Somehow windows does this without destroying flash drives, I
wonder what the trick is.
