Hello all. New to the forum. I installed a 2tb ssd and an 8tb WD purple HDD in my Dell Optiplex 5060 tower as additional storage (Not boot). Both are internal drives. The 2tb drive showed and is working up fine. The 8tb WD drive does not show up in File Explorer, Disk Management, Device manager, or DISKPART/LIST VOLUME. There was no detectable sound (spin up) when booted the first time, nor when connected externally via a USB to SATA cable. The drive was purchased from an Amazon seller and I am working with them on a solution. That said, I am curious as to the reasons this happened. I look forward to seeing responses from forum members.
