I am having trouble adding a second drive in my pc. Whenever I connect the second drive, it does not appear in my computer. I ve tried to set the master and slave settings, but I cant seem to get it right. After playing around with it for I while, I got a blue screen of death, restarted the machine and got the "operating system not found" error. I checked in the bios and noticed that the hard drive is not even detected. help please.
