Hello, I ran into this problem today, I bought new SSD and HDD, and I connected them with two SATA DATA CABLES and both with a SINGLE SATA POWER CABLE with 4 sata pins on the cable. But when running windows it does not show the HDD still. At first I though it was my SATA motherboard Cable but then I checked and it wasn’t the issue. I don’t really have the second pin out cable for SATA. Do i have to buy one or is it not the issue ?
