I'm looking for a Mac OSX program that can compare two drives and tell me which music files are not on one drive.  Does anyone know of a good <$40 program that can do this?  I'd like to find some that's $20 max but can't find anything.

I haven't used it, but Sync Checker looks like it would fit the bill.  You can download a demo version that stops automatically after detecting 200 differences (the full version can detect 50,000 differences).

Thanks.  I think the issue will be the 50k file limit.

Maybe I'm misunderstanding it, but I think the 50,000 file limitation is not the number of files it can compare, but the number of differences it can analyze and report on?

If you're comfortable with using Terminal, rsync will do exactly what you want and it is included as part of OS X.  If you only want to know the differences, make sure to pass the -n flag.  Otherwise, rsync will copy the missing files.  If you open terminal and run 'man rsync', it will tell you all the gory details.

Assuming the directory structures are the same you could use diff - http://hints.macworld.com/article.php?story=20070408062023352

Failing that you'd have to cook up something with find....

Let us know how you get it done thx

A good friend of mine uses Beyond Compare on his Windows and Linux machines.  He said he wished that they would do a Mac Version.  I sent them an email asking if they would ever do it. 

Here is the response:

The current version of Beyond Compare ( 3.3.8 ) is only available for Windows and Linux.

Beyond Compare 4 will include a Mac version, we hope to release it around the end of this year.
