This problem has been known for a lot longer time. However, "most people" only complain about it - and they also think it is easy to fix this problem. Well, it is not easy - in fact it is very hard to fix this problem. For data on this, please search the mailing list archives of FreeBSD. > anybody knows any work-around ? Yes - the work around is this: don't do that! Do _not_ remove any mass storage device before unmounting it. If you can't learn to live with this workaround, please do not use removable mass storage devices with FreeBSD. HTH -- Regards, Torfinn Ingolfsen
