Hey guys, I have just finished building my second gaming PC. Everything is working perfectly, when I installed windows I selected my SSD to install the OS on instead of my HDD (which was on the list). However now I am using my computer, it is unable to locate the HDD when I attempt to save files or install games. It is however in the device manager list: ST2000DM001-ER164. Not quite sure what has happened, as this did not happen last time I installed my hdd/ssd. Thanks for any help in advance.
