[Keeping a record of what's on each disk?]

Virtual Volumes View (http://vvvapp.sourceforge.net/) is what i use to achieve this.

It's not perfect but if you have all drives mounted to a Pool-Folder like Chris does,

you can simply index that folder and the output might be a bit more navigatable than simple textfiles.

 

Virtual Volumes is REALLY GREAT... it also has the Update function, Search Function....

REALLY GREAT... the only disadvantage is that i have to run it regularly
