This topic has been discussed at length on this list. Please search the archives. Conclusions that can be drawn: 1. Don't do that (If you're going to do it, try umount -f). 2a. Disabling write caching is the only way to get USB storage to be near hot-pluggable. Major write performance degradation is guaranteed. 2b. A non-trivial amount of work is needed to fix this. A suggested fix would be to rework the way that GEOM and CAM work together so that additional state information is passed (In the past, this topic has brought about two dozen Trek bikes, four bike racks and a lovely $COLOR-painted bikeshed).
