Can you recommend a hard drive cataloging application or approach for Mac OS X (preferably native -- not a WineSkin approach)? It does not need to be compatible with El Capitan just yet.
More details on my specific needs/requirements:
I have a few dozen external hard drives, and would like to have one master catalog I can search for that elusive file when needed, without having to plug them in.
Ideally it can also be updated every time the drive is plugged in, and have robust searching abilities. Extra points if it uses Spotlight's robust and native search capabilities as well.
Printing drive contents is not an option.
Extras but not required:
To throw a wrench into the machine, it'd be a perfect world if this cataloging could be kept up to date via a cloud (such as my Dropbox account) but I think this would be asking for too much!
