The WD 1TB HD is suddenly not mapping on my gaming computer. It is several years old so I assume it has died. What/how can I check to verify. Some years ago I had a SATA cable go bad on another device so I guess it could be that. Is there a way to wake up a dead HD. It's not a huge loss because there are only game files and photos stored there and a few apps. I had to replace the OS drive with an SSD a few years ago. The case has three more HD bays so I'm just going to install a 2TB gaming HD. It seems that my backup HD which is connected to my router is also inaccessible but it does map. That could be a sharing issue. I would appreciate thoughts. Thank you.
