It was a 500G that was out of warranty. I was able to open it up and found a standard 3.5 inch SATA hard drive. I directly connected it to a computer and the drive was totally dead. If the drive was connect to one of the first four physical drives that bios checked, then bios would halt and freeze. If it was connected through an add-on SATA card, then it bios would not recognize it. I purchased a replacement 500G SATA drive from NewEgg that was on sale and was able to install it in the original MyBook box. It is working perfectly. The drive I purchased carries a 3 year warranty as an added benefit whereas the MyBook is only a year. The controller is what make the front light operate and has nothing to do with the drive. The other thing you might want to check it the power adapter. The other MyBook failed in the exact same way but when I changed the adapter it was just fine. I hope this helps but YMMV Good luck Robert
