How can i fix my i-pod?

I lost my usb cable to conenct my i-pod to my computer. So i just bought a new one, i hooked it up and realized that my i-pod froze. After awhile i finally got i-tunes to read my i-pod except it said "i-pod currupted restore." It didnt read my i-pod as Jenn's i-pod. So the first time it was restoring it froze everything. Now i am restoring it again, and its taking a long time. Is is working? How can i get my ipod to unfreeze?
