Shawn, I haven’t changed any DirectoryFactory setting in the solrconfig.xml as I am using in a local setup and using the default configurations.
Device has been unmounted successfully (confirmed through windows message in the lower right corner). I am using Solr-4.10.2. I simply run a Ctrl-C command in the windows Command prompt to stop Solr, in the same window where it was started earlier. Please correct me if something has been done not in the correct fashion.

If you are using the default Directory implementation in your solrconfig.xml (NRTCachingDirectoryFactory for 4.x and later, MMapDirectoryFactory for newer 3.x versions), then everything should be persisted correctly. Did you properly unmount/eject the removable volume before you unplugged it? On a non-windows OS, you might also want to run the 'sync' command. If you didn't do the unmount/eject, you can't be sure that the filesystem was properly closed and fully up-to-date on the device. What version of Solr did you use and how exactly did you start Solr and the example? How did you stop Solr?
