I have a Pi-Desktop case with the SATA bridge, and it no longer sees the /dev/sda target. I am unsure if it is a bad SSD or a bad bridge. I don't have another mSATA slot to check it. I have poked around, but I can't find a likely piece of hardware that would seem to be the bridge. I have tried lsusb, lshw, etc. Is there away I can inspect the bridge to see if it is operating?
