I install my second hdd from my old computer to my new computer as a second hdd because it was a 2 tb hhd which I use it as store. But after I turn my new computer on, bios didn't detected the already formatted drive and Disk management doesn't show anything. I didn't copy the stuff on there because it would take about a week and a half to get off there and some of files is too large fit on dvds. It even has new sata cables.
