Is there a way to view a sync log to see what Itunes has deleted from the Ipod?

On a Mac, you can use iSync to see a log of all changed data on the
iPod, or other media strage device that supports logging.

There is no actual "changelog" file on the iPod that will tell you
what it has been up to, but if you really must know, you can just see
what all you have in iTunes, and whether or not you have the entire
library synced, or just a portion.  When you do chhose to have the
songs updated automatically, the files (MP3's, AAC's, MPG's, etc.) on
the iPod will be an exact duplicate of your iTunes Music folder on
your computer. (This folder is where iTunes automatically copies all
your music)
