if the music is on your ipod download yamipod and you can rip it all straight off and put it on ur hdd

if not look for hdd recovery utilities/progras in google

download them from Mininova : The ultimate BitTorrent source!

using bitlord

it should be able to recover them, as when you delete something from your hdd you dont actually delete it you just flag it so it can be over written. your best bet is not to defrag, load anyhign new. till you have looked as it could likey over write it.

if you have done a system recovery on your ipod it is unlikely that it will be there.

hope it goes well.
