If everything goes well, dd will tell you how many blocks were copied, and then you can disconnect the iPod (maybe you'll need to eject it first), and it will restart and load the new firmware. If dd reports errors, you might be able to use the number of blocks successfully copied to locate the bad block that caused the stoppage.		*Now you can press return.

			I used Restore Your iPod Firmware WIthout Data Loss at http://www.techspikes.com/2009/10/restore-your-ipod-firmware-without-data-loss/ as inspiration for this tutorial. It describes how to do the same thing, but in linux.

	See http://www.openobject.org/isop/?p=47 for how to re-partition an iPod's hard drive so that bad blocks are part of the partition-map partition instead of the firmware or data partitions. I've successfully used the routine there, but with a firmware partition twice the size. Make sure you're using the right size for your device by listing the existing partition map and printing it or saving it in a text file. I also made free space partitions usable space instead of enlargening the partition map, which doesn't always work.
