thanks again Kenichi Watanabe for responding.
i had in fact done a restore on my ipod when i was prompted, and it was from this point onwards things went out of shape.

I'm not clear on whether you did a Restore on the iPod or not...
If you did (a Restore), and all of your songs are stored in your iTunes music library, you may just need to set up automatic syncing for the iPod.
First, if the iTunes sidebar (along left side of iTunes window) is not visible, from the iTunes menu bar, under View, select Show Sidebar.
Connect iPod. In the sidebar, find the iPod under DEVICES, and select it there. To the right, and toward the top, there is a bar of buttons that starts with Summary. Click on Music next to Summary. This is the iPod's Music screen, where you tell iTunes how to sync your iPod.
Check the box for Sync Music. If you just did a Restore, there is nothing on the iPod currently.
NOTE: If you did not do a Restore, AND there are songs on the iPod that are not in your iTunes library (on the computer), do not proceed. When you set up automatic syncing, any songs on the iPod that are not in your iTunes library will be lost.
If your entire iTunes Music library fits on the iPod, you can choose to sync Entire music library. With this setting, everything in your iTunes music library syncs to the iPod. Going forward, any changes to the iTunes music library sync automatically to the iPod, the next time you connect it (or when you click Sync).
Otherwise, you can choose to sync Selected playlists, artists, albums, and genres. Then select (checkmark) the playlists, artists, albums, and/or genres that you want on the iPod, from the lists below. For example, you can put all of your favorite songs on one or more playlists in iTunes, and select those playlists on the iPod's Music screen, under Playlists. When you click Apply, your song selection syncs to the iPod. Going forward, changes to the iTunes music library (based on how the iPod's Music screen is set up) sync automatically to the iPod, the next time you connect it (or when you click Sync).
i actually wasn't able to access any of the normal menu functions on itunes because it automatically tried to sync with the device regardless of whether i had checked that option. i did try and use the 'sync selected playlist' option which did not help, as the sync process was still laboured and in the latter stages of my desperation (after rebooting ... uninstalling .... reinstalling etc...) itunes was showing error windows with -50. which i investigated btw.
so i did conclude that my ipod had been corrupted.
i have a good friend who own(ed) a similar ipod classic in near mint condition who agreed to sell it ...and as a result i have now a device which is now working.
and am a happy camper again.
having gone through this process of installing updates (and updates, :/) i am a little wary of doing so in the future, as i know my pod did function before.
and as an aside, i do prefer the earlier format to this current one. i don't find it as easy to navigate (though it is not that hard) and it isn't as pleasing on the eye, which i thought would be the point of any marketing tool.
