I put my OS and a few other things on my SSD but now I want everything else to save onto my HD, and I cannot find where it is because it doesn't show up anywhere.
When you use Disk Management, remember that both the upper and lower RIGHT PANES will SCROLL so you can see all each contains. If your HDD shows up OK in BIOS Setup, it will be in the LOWER RIGHT pane where you can work on it.
Yes I've tried all this before. It doesn't show up. I put my OS on my SSD, that works fine. Even my CD drive shows, so does my external drive. But my Internal HDD will not show up in Disk management. I see it in Bios, is there anything I need to do?
When I connect everything I hear it spinning
It is hard for a HDD that is detected properly in BIOS Setup to NOT show up in Disk Management. However, you have to look in the right place.
In Disk Management, look in the LOWER RIGHT pane. SCROLL if you have to, to see all its contents. This is where you will see valid hardware devices that Windows still cannot use because it does not understand the device. That is the case for a totally blank new HDD with no data.
