Hi. I have a 5Tb Seagate internal hdd that I tried to move to a newly built desktop. It is visible in bios and disk management but not in my computer and I can't access it in disk management. Disk management says it's not initialized but when I try to initialize it, it can't find it. The drive is visible but there is no black or blue bar next to it. I've tried connecting to other SATA ports and cables with the same results. If I put in external hdd enclousure, Seagate tools sees it and basic tests show it's working properly. Seatools does not see it if installed via SATA connection. When I put it back in the old desktop, it works just fine. I even transferred all the files and reformatted in the old desktop but putting it in the new one results in same problem. Any ideas why this is happening and how I can fix it? Thanks.
