I had a Samsung 860 EVO 4TB SSD installed in my HP EliteBook 820 G4 on the SATA port. It was running Windows 10 flawlessly for 3 months until I updated the BIOS last night and the BIOS no longer recognizes the SSD. I tried rolling back the BIOS to the previous version but it still won't recognize the drive. I took the drive out and put it into an another older HP EliteBook and that computer doesn't recognize it either. Any ideas why my SSD isn't being recognized anymore?
A spare 500gb HDD I had is recognized by both laptops.
After running the hardware diagnostics via the BIOS, this is what it says when the drive is installed: https://i.imgur.com/nxgbjza.jpg
This is what the hard drive diagnostics says when the drive is NOT installed:
Obviously the drive IS being detected because the diagnostic is giving two different results when it is connected and not.
