Let me see if I can summarise the solution that worked for me based in Gailpods instructions
1.Download and install the HP USB formatting tool from here:
ftp://ftp.compaq.com/pub/softpaq/sp27001-27500/SP27213.exe
2. Attach the nano and put it into disk mode:
(From 'SoniaC's post)
Move the hold button on and off the press menu and the centre select button at the same time, after 6 seconds the Apple logo will appear - then hold down the select and play buttons at the same time - the nano should flip to disk mode.
I did not have to restart the computer at this point but you might try it if the first run through this doesn't work.
3. Close iTunes if you have it running.
4. Kill the iPodService process.
Do a Ctrl-Alt-Del to pull up the system dialog and click on the 'Task Manager' button.
Select the 'Processes' tab.
Select iPodService.exe process and press the 'Stop Process' button.
5. Start the USB formatter application from step (1) and format the nano drive to FAT32.
6. Once it's formatted run the updater application.
7. The 'Restore' option should
now be available to you. Select restore.
You nano should now be working again. All music that was on it previously will obviously have been scrubbed.
