I have a 264gb Samsung ssd as my boot, motherboard is z97 saber tooth asus mark1 i7k core, recently trying to add my 3tb Wd red drive for games movies everything but my key games I have on ssd. When I reboot it doesn't want to boot even on the bios it's not on the list trying to boot so that confuses me. Also the boot process when it does go through my boot is like 4 minutes sometimes longer, and let's say I get past that point, computer starts running really slow and sometimes lags. I portioned the 3tb as two 1.5 tb partitions. I went to asus to update bios. Still running slow or doesn't boot. Depends on how it feels. Please help with some helpful hints or solutions please!!!
