Hi, I got an Xbox Slim last night and I want to transfer the content from my old Xbox (external HDD) to the slim. I looked on-line and they showed that any of the official HDD transfer, whether new or old, will help with this issue. I followed the instruction except, I don't the pop-up screen that tells me I can transfer. I went to the storage and it doesn't show the hooked up HDD. Any idea on how to proceed?
