I have multiple Corsair 90gb/120gb/240gb SSDs that won't show up on my PC. I have one working one and it did show up and I was able to reformat it. The SSDs won't show up in Device Manager nor in Disk Management. I tried different Sata Cables/Power cables and they don't work. They could all be dead, but I took the casing off one of them and the power LED on the inside lights up when the PC is powered on. I'm testing these on my Bench Tester and I can't verify these in Bios because for some reason I can't get into Bios, so I wanted to see if anyone had any idea on how to get these SSDs up and running again.
