Extract Photos and Music From iPod
iPods - older than the iPod Touch, can work in "Disk Mode". This means that you can use File Juicer's features to extract files from the iPod.
This is mostly useful if you have lost your Mac, or all data on your Mac.
Then the images on your iPod may be all you have left, and while they are of lower resolution in ithmb files, they are in TV quality and certaily better than nothing
Music on the iPod is exactly as when you had it in iTunes, so the files you recover that way are fine. MP3 files get named according to the tags inside, while MP4 files must be imported into iTunes before you see the info about the song.
Connect the iPod
Connect the iPod to your Mac. Do not synchronize it yet as that may remove what you have got on it already.
