Just to close this thread – It looks like it’s working fine now. Not sure what mistake I had done last time. But now, the index data is still persistent on the pen drive even after server shutdown and restarting it on a different machine where the pen drive is plugged in.
Thanks for all your help..

I haven't tried moving it to a local hard disk, as I wanted to work on two machines (work and home). So was using a pen drive as the index storage. Yesterday, I did the complete indexing and then unplugged the drive from work machine and connected to my personal laptop. Data folder didn't exist. Erick, As per your earlier suggestion, I am using Tika and SolrJ to index the data (both binary and as well database content) and the same had been committed using the SolrJ UpdataRequest. I was able to see the data in the admin UI screen and even performed some searches on the index and it worked fine.

Were you able to see data in the admin UI _before_ you unplugged the drive?
