Hi there and be welcome!
Like always, there is more than one possible cause for this problem (and of course, more than 1 possible way to solve). Let's start with the most obvious thing first I'd say :). What you do, is delete both the drives from the device manager. After doing so, WIndows will ask you if you want to reboot. Do so! Upon the next boot, Windows will re-recognize the drives. If you're lucky, the drives will work again!
If not, feel free to tell us so we can dig deeper
