Use YamiPod to extract the misic from your iPod. BACK IT UP somewhere and restore your iPod. Drag and drop your music to your iPod via iTunes and voila, you have a working iPod!
Alright here is the dealio...
80 gig Ipod Classic
OS- Windows Seven
Itunes- Up to date, but I currently uninstalling it to try an older version.
As with many Apple products life was great until...well I don't know what the hell happened. My Ipod was playing fine, I then plugged it into my new laptop to manually add some new music. Thats when a message flashed that certain files were missing, didn't think much of it until I ejected it and found ALL my music was gone. So I plugged it back in to find Itunes does not acknowledge the existance of my Ipod. However, my computer does and it shows that there is about 35 gig (the amount of music I had) worth of space still taken up on the Ipod. The Ipod works fine unplugged, minus any music.
Now I have tried nearly everything...
The 5 R's (restore, retry, etc...)
Uninstalled Itunes and all Apple files attached
Put the Ipod in disk mode
Changed the drive letter
Turning the Ipod off while plugged in
Gently pleading with Itunes to please forgive my Ipod for whatever it did...you get the idea
Well any ideas? I really can't stress enough how badly I need the music on there now. As with most young men I have choose to ignore previous life lessons that showed me the importance of backing everything up.
Please...Please Help Me
