I am looking for software that will allow me to search for files that are saved on external hard drives without having to be connected to them. I want to be able to locate a file from a kind of virtual index of the hard drive - ideally the file structure and search functions would resemble OSX, except it would only have names of files, not the data itself. then, when I know which hard drive the desired file is on, i can plug in just that drive and retrieve the file. make sense? there's something for PC called datacatcher that seems to do this; haven't found anything for mac. thanks for any help!
