I have a Z690-A Asus motherboard. In M.2-2 slot I have a crucial P5 Plus 2000GB. I have two Sata hard drives attached. I replaced my 4GB sata drive with a Power PCIe XS70 4GB SSD Drive in m.2-4 no problems. I was changing my 2GB Sata drive out with with a Power PCIe XS70 2GB in M.2-3 slot when I do this the hard drive light stays on steady. I have tried all combinations moving to different slots. Asus says the Power SSD is compatiable with the mother board but I wonder if there is a conflict with the Crucial SSD? I also have a second computer with the same specs. I was changing out the Sata drive when I installed the Power SSD the same problem showed up. Any help here.
