I have an old laptop sata drive that I want to use as a storage device. It is a 500 GB WD. I have it plugged into a SATA bridge so that it can plug into my computer. When I plug it up, it doesn't show up, but rather shows up as a greyed out F drive. I can't access it so that I can format it? How do I access this drive. Even when I unplug it the F path still shows up on my computer panel.
