Q: Corrupt iPod Classic (1429)

Hello! I own an iPod Classic (120 GB) since a couple years now and it has never given me any problems. Recently, after i bought an album on itunes, when i plugged it in to synchronize it, my computer tells me it's corrupted and i need to restore it, but when i try to restore it it makes it so far but then it says it cannot restore, and that's when it says "error 1429"

The stats of my iPod are:

Retracts: 375

Reallocs: 938

Pending sectors: 9

Poweron hours: 2905

Start/stops: 373

Temp: current 25c

Temp: min 12c

Temp: max 45c

Does anyone know what should i do to fix it?
