Unplug Ipod without safely eject. Now no music in Ipod and Itune can't identify it.

Hi all.

Last night, I unplug my Ipod Gen 7 without clicking on "eject" and thought everything was normal (most of the time I do safetly eject first) until the next morning. Before heading to work, I turn my Ipod on and there were no musics in it.

I then plug into the pc and go to Itune. I notice the following two things will happened depending on my actions.

1 Click on Itune and then plug in the Ipod. Nothing happens and the Ipod listing doesn't shows up underneath Music Playlist.

2 Plug in Ipod and then click on Itune. It become slow to appear and when it does appear, it may lag which prompt me to go to task manager. When it stop lagging, I get a message saying "An iPod has been detected, but it could not be identified properly. Please disconnect and reconnect the iPod, then try again.

As far as I know, Itune is up to date and my pc still pop up and recognise the ipod so I assume the device driver is fine?

Also the Ipod itself now shows zero music. It is also version 1.0.4 PC and model MD479QB

I thought it could be Itune is at fault but since there no music in my Ipod at all, I'm assuming the worst here. By unpluging it first, I untentionally corrupted my Ipod? I mean my Ipod Gen 7 is very old now (over twelve years old now). If there is a way to fixed it, I will try but now I am thinking wheather to get a preowned version or just get an mp3 player altogether?
