Hi i have the os installed on the SDD and now want to install my hdd. So i plugged it in and turned on the computer but it doesn't recognize another drive..... Do i have to install the windows 7 OS on both Drives ? or is there something else i'm supposed to do ? I basically just want the HDD as a storage device. Also this is a second example i need answered haha my sdd needs to be upgrade but can't be the primary drive. If i don't install an OS on the HDD can i still make it a primary drive to update my SDD firmware ? or do i need a OS to do that ?
