I have a 2.5 inch SATA Hitachi 320GB 7200 rpm hard drive. I want to put it into a desktop system with SATA. I have read that there are power concerns about 12v and I have read that SATA is SATA and it doesn't matter. Can someone truly say for sure which is the case? I have not had any luck running this 2.5 inch drive in my desktop. I can see the drive in BIOS and see it in the operating system and I can see the SMART status showing the drive is healthy but I can not format read or write to it and I just don't understand what gives.
