Thanks in advance to anyone willing to help. I have two HDD's one is 160Gb the other is a 3TB Seagate with 1.5TB partitioned. I reinstalled windows on the 160GB were it was before and 1.5TB partition is now not showing up. It detects the drive and it is assigned letter E: just as before. Its in the bios and has drivers but the 1.5TB partition is not showing up in disk management either only the 1.1TB unpartitioned space.
