New Hard Drives Are Working, but Not Showing

I know there are some simular topics, however i havent found one that matched my situation.

Problem:
- Hard drives are working, but are now showing in My Computer

Some Info:
- Brand new hard drives
- Updated BIOS to newest one successfully
- BIOS recognizes the drives
- I tried uninstalling and reinstalling the drives
- I rebooted a couple of times

Some pics:

I'm confused. The title says the drives are not showing, the text says they are now showing. The first screen shot shows the drives. What's the question?

i should be having 4 hard drives in My Computer, not 2

Look at the jumper settings & cable position. The drive might come set for master but they can't all be master.

You need to go into disk management and probably set the drives to online or initialize them.

Right click Computer in your start menu and click Manage. Click on Disk Management and see if your drives are listed.

Any update on this?

I think there are not created .
Go in disk management and check their status
