Q: 1439 error what is this

I assume you have tried everything here?

iPod: Cannot restore or update in iTunes with error 1415, 1417, 1418, 1428, 1429, 1430, 1436, or 1439

It could be an indication or a damaged or dying hard drive.  I would recommend doing a disk diagnostic on the iPod's HD using the instructions given by turingtest2 in this older thread.  He also covers what the resulting numbers indicate.
