iPodDisk is designed to make it easy and intuitive to copy music off iPod; it enables you to do so within the Finder, or whatever application that can read files.
Tight integration with Finder
iPodDisk isn�t exactly a tool that copies songs from iPods; instead, it enables other applications to do so by emulating an iDisk drive.
After it starts, iPodDisk automatically opens a Finder window. You can browse, drag from, or even play music directly on the drive. From a user�s perspective, there�s no difference between the emulated drive and regular local folders, with the exception that iPodDisk drive is read-only.
Search your music with Spotlight
Most �get music off iPod� applications come with built-in search functions, but iPodDisk doesn't.
Instead, it works with Spotlight.
Copy your music, your way
You�re not restricted to Finder; any tool that can read files will do.
Ever wonder what filled up your 40G iPod drive? Again, you�re not restricted to �cp�; all commands capable of reading files will do - tar, scp, rsync, and etc.
You can do the copy in the terminal even without iPodDisk. But iPodDisk also provides a convenient hierarchy structure well organized by artists and albums.
