Q: I can not restore my ipod classic error  1430  what do i need to do

I assume you have worked though each and every suggestion in this Apple support document?

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

I would recommend doing a disk diagnostic on the iPod's HD using the instructions given by turingtest2 in this older thread to check your Hard Drive's health.  He always covers what the resulting numbers indicate.
