BIG problem when upgrade the HD

Hi,
i have a really big problem with my apple tv.

Recently i have upgrade the apple tv HD and i have save the imagine of my original HD on my mac.

Then i have to re-upgrade the HD and i try to do this with the imagine that i have create but i discovered that the imagine is now 35mb and not the original 40gb and produce and error when i try to activate it.

SO NOW I AMM WITHOUT A IMAGINE OF A “VIRGIN” HD

I try to do a simple copy with carbon copy cloner of the old HD but when i try to install the atvflash the installer produce a error.
I suppose why the HD i made is without the recovery partition.

Have you any idea? Or better have you a imagine of an “virgin” apple tv to gently share…

Thanks a lot, Matteo

The actual available space for syncing on the AppleTV is about 32GB. Is that what appears in iTunes?
