VVV: Virtual Volumes View (fsoft.it)

Not to be confused with Varying Vagrant Vagrants ( https://github.com/Varying-Vagrant-Vagrants/VVV )

This software is excellent for keeping a fast local searchable catalog of the filenames from all your drives, even after they are unplugged or powered off.

I found vvv after looking for something that can replace Sisoft Sandra.
