	Before I tried [[Replacing corrupted recovery OS with one from Apple]], I was desperate, so I downloaded an image of somebody else's ATV, the first 2GB of a 2.0.2 system, and copied it onto my hd. It started with a curious linux penguin splash screen, then I did a factory restore. Although it copied only the first 2 GB, it still had a partition table that thought the disk ended at 40GB, so the Media capacity is only 32GB. I removed the Media partition (4) and replaced it with one that fit the empty space. Then I (too hastily) put the drive in the ATV. No matter what I did, factory reset to running diagnostics, the ATV still showed only 32GB capacity.

			Solder a power switch onto the cord, so I don't have to unplug, with accompanying spark, to shut down/start up.

	;dd:The disk duplicator utility is excellent for copying data from and to disks verbatim. You should unmount disks before use so that the disk isn't changed in the middle of a copy. Use a large blocksize to speed copies, with the -bs switch, e.g. "bs=1m". The blocksize, in bytes, changes how much is copied into memory, which buffers reads and writes. The larger the buffer, the faster large transfers. bs can take numbers and popular suffixes, like k and m. The actual blocks on the disks are probably 512b, but that has no relation to dd's settings.		;dd:The disk duplicator utility is excellent for copying data from and to disks verbatim.

			====Retrieving the old settings, so iTunes thinks this is the same ATV====
			If you make a new Media volume, or use someone else's then your iTunes will not recognize this as the same ATV, and you will have to remake all your sync settings. If you've made complicated settings for podcasts, or have a system that is keeping track of what you've already watched, you'll regret this.
