If I understand you cannot see the drives in Windows Explorer. Device Manager recognises the drives.
Click the bottom left start orb and type "Disk management".
Do you see your drives but no letter then (not for recovery or system reserved if you have one) right click and assign a letter.
A screen shot of Disk Management would be useful. Use the Windows snipping tool and the little paper clip icon on the top of the post to make and upload the screen shot.
