Hello, I believe I have successfully flashed my drive with the 500 gig security bin file. However, the drive is not seen by the 360 at all. I always get "No storage devices" HDDHackr does not throw any errors when flashing or formatting. FATXplorer tells me the drive's security sectors are valid and everything. So I have a couple of questions 1). Should HDDHackr change the serial number of the drive? The one I can see doesn't match the one that is displayed when flashing the drive (the one I see starts with an A) 2). Speaking of the serial number, should the one from the security bin file have a bunch of spaces in front of it? 3). Opening the drive in Hex Workshop and looking at sector 16 onward shows what I think should be there. Should I look for something else? I'm doing this because the Xbox 360 I have was picked up at a thrift store and has no internal drive. I'm just trying to "make it whole". Thanks for the help!
