Craig Wright claims to be Satoshi, and a Florida court has ordered him to list all of the addresses with his bitcoin.
Apparently he burst into tears in court because he couldn't provide the addresses. What a wuss!! It's time he was locked up to stop him trying to mess up Bitcoin.
Your saying it isn't possible for Satoshi to lose his usb drives?

I'm certain those 1 million bitcoins will be moved someday, whether Satoshi has them or he passed them on to someone else.
The only people who lose their hard drives or USB keys are novice computer people. Its something that would happen maybe to my wife or my dad on the computer.
Most saavy computer people, especially a highly skilled programmer like Satoshi, always keep backups and they probably got some full-proof RAID setup incase one hard drive fails.
He didn't lose the keys. He either destroyed them on purpose or he maybe had some unexpected death and its the reason why he never spent them. Or maybe he is alive and well and just spending the newest mined bitcoins not to attract attention.
