1TB hard drive for gen 1

[potatis]

I extracted the 3 dmgs from the original appletv hard drive and put in a 32gb ssd using the "prepare a hard drive" instructions on ankwardtv. No problems so far, but using the same method with a 1tb hdd doesn't seem to work. Neither does atvdrive or atvcloner apps. Disk drive utility shows the recovery and osboot partitions to be 3 and 7 gb respectively, which is a bit odd, but the block nummers are correct as far as the terminal shows. What could be wrong?
