Running iTunes on Windows, whenever I try to update my iPod, I get the following error dialog:

Windows - Delayed Write Failed
-
Windows was unable to save all the data for the file \Device\Harddisk2\DP(1)0-0+6\iPod_Control\Music\F09\07 Cryin_ Won_t Help You No.mp3. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.

This doesn't always happen after the same amount of time - it may happen after loading 50 tunes, it may get to 150. It's not always the same tune, either.

The iPod will have frozen at this point, and needs a reset. Sometimes I need to reload the iPod software after this happens, sometimes not.

I've recreated this issue connecting to two seperate Windows machines, so whatever the problem is, it's on the iPod side. I rang Apple Support, and they suggested that I re-format the iPod's HD. I'd thought that reloading the iPod software did that, but apparently not.

I'll try this when I get home. I can't do it now - I'm on a client site in Orpington again. Wish me luck, 'cos if that doesn't work, it's got to be sent away to the menders. :-(
