Indexing software for shelved hard drives?

Here's a question for backup enthusiasts out there.
Is there some sort of freeware / shareware out there that'll index a hard drive for you and then keep a database or something that you can search?
Let's say, for example, you have a 1TB external drive that you want to shelf. You pull out the drive, put a clean one in, and you put the old drive away. But then say I want to check if a certain file is on that drive. I'm looking for a quick way to scan through an index file of that drive to see what the contents are without having to mount the drive.
Any thoughts? Thanks!

Oh sure, lots of disk cataloging programs!

I happen to use one called Disktracker out of sheer laziness (been using it since OS 9!), and there are many others. Just do a google or MacUpdate search on mac disk cataloging programs. If you own Toast I believe one is actually included in the bundle.

I use the one that comes with Toast. It's fairly basic but it does the job.

I'm using the excellent CDFinder software I have got no complaints.
It can catalog hard disks (internal and external), server volumes, DVD-ROMs, CD-ROMs, iPods, Blu-ray, and USB sticks.

Download CDFinder for Mac - Catalog your external media and disks. MacUpdate Mac Software Downloads
Download DiskCatalogMaker for Mac - Catalog your disks. MacUpdate Mac Software Downloads

Thank you everybody for your suggestions!
I'm on my way to better data management.
Cheers!
