after replacing hdd device showing bad reallocs and pendings

After Buying a new hard drive off this website and replaced it successfully formatted to fat32 64 cache

restoring it with itunes and then syncing music to the device my smart data shows..

Retracts: 39

Reallocs: 512

Pending Sectors: 216

I personally don't think this is good, obviously correct me if i'm wrong in the last restore some of my songs were on the device but not playing. Do take in consideration that this is meant to be a working and clean new hard drive? Need Help Badly!!
