Greetings,

I recently installed a 1TB Toshiba hard drive and it has begun showing signs of communication difficulties. I think I may have stressed the ribbon cable when I installed the drive. I would like to try reseating the cable but I’m not sure how to properly unplug it without causing further damage. Below are the messages I see from the boot sequence that are causing my concern:
