Hello ALL !

I have a Dell Precision 5530 with 32GB RAM, 1TB NVMe and I am trying to add the second SSD option.

I purchased the necessary cable and have tried several BIOS settings (recommneded on various chat/help) and I have also tried several Hard Drives and absolutely nothing shows in BIOS and consequently Windows.

Its it a bad cable or what else can I try to diagnose ?

Thanks in advance for the help 

James
