The storage drive on our BI server died yesterday, and all the video data was lost. The program and database are still fine though as they were on a separate SSD. So after replacing the video storage disk, is there anything special I need to do to get rid of all of the thumbnails for all the previous recordings that no longer have video attached to them? A database cleanup or anything? Or do I simply just manually delete them in the BI interface? Thanks.

I think delete and regen the database from BI5 settings should sort it.
