Windows tries to auto-mount anything it can get its hands on and thereby tries to set, among others, the dirty bit (indicating the volume needs to be unmounted first - the thing that makes your computer scandisk if you don't shut it down properly). Most of these tools work by having a proven (mathematically) bottom layer that mirrors writes so that they cannot be actually written and are written by having an upperhand interface with reads and writes and a lowerhand interface with only reads. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
