new 160gig Classic Freezing up

[wesdog]

Ok I got the thign all loaded up last night and saw a few glitches iTunes made so I went and corrected them then plugged my ipod up to laptop. The ipod was already turned on as I was going thru cover flow to see what artwork was screwed up. When i pluged in usb cable itunes didnt see my ipod and the ipod had no connected message. I clicked disconnect on laptop for device then removed pod to a frozen screen. Now on my old 30 gig 5th gen all I had to do was move the hold button back and forth a few times rapidly or hold in the select button and down on scroll wheel for a few seconds to reboot pod, neither works on this one. The backlight is still on also so battery will drain fast but wanted to edit the pod before battery dies, lol. Any new tricks to reset these things yet?
