Looks pretty suspicious or a joke. Having a hard drive with 400 million dollars, instead of finding the best masters in reality, he goes to the forum to ask... Are you the author? gkelly 15Z5YJaaNSxeynvr6uW6jQZLwq3n1Hu6RX https://bitcointalk.org/index.php?topic=24346.0 Make a complete copy of the hard disk (image) and upload it here and we'll see what you can do 

Once upon a time there was a boy named (redacted). He used to go by the alias gkelly. He got involved in mining bitcoin early on. He was successful in mining 7000+ bitcoins which he stored in his wallet. He used his laptop to mine them. After a while summer came and it was too hot for him to handle both his wife and the mining laptop. Thats when he decided to choose his wife and stopped mining with his laptop. Days went by and his laptop was got too depressed to live and finally left this world. Although he died his organs were salvaged by glelly. He stored the HDD which stored his wallet which stored his bitcoins. And few years later without realising, he was losing millions of todays bitcoin worth, he dumped his hdd in the bin. And by the time he realised how much he fucked up the poor HDD, which stored his wallet which stored the bitcoins, was already buried 7feet under all other discarded rubbish. Thats the story how gkelly murdered those many bitcoins with no trace of the incident except the blockchain which stores the information on that poor soul. And legend says it still haunts people visiting the pile of garbage looking for treasure.
