So my ssd been acting weird lately, I've been checking it with crystaldisk info and Sandisk's own software and it listed as Sata 3gbps sometimes while 6gbps other times(after restart). So I bought a new SSD and did a fresh install of windows there(since its faster, PCIE M.2) and the SSD still on weird switching between 3 and 6 gbps so then I thought I try doing firmware update that SSD dashboard been asking to do and that did not fix it. So then I found a setting in Intel Rapid Storage technology which is called "Link Power Management" and it's on "Enabled" by default and so I went on and disabling it. After that the SSD been on 6Gbps and I thought well that fixed it and then today SSD just disappears from windows and not detected in BIOS either, could it be dead? I tried different SATA cables and ports and its still not being detected. It is slightly a year old and still in warranty. I even try switching its place with my HDD and it still doesn't show up.
