so i just did a dban and a format of my hdd. it worked all fine and stuff, then i wanted to install some games on it and left the pc, the pc then went to sleep mode, and when i turned the pc back on the hdd wasnt there anymore, i tried to switch sata cables, did not work. idk what could be wrong, i can fell that the drive is getting turned on but it not showing up on the pc, what to do?
