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.

Have you tested the drive on a working computer with a simple SATA to USB controller? Just to see if it still alive?

You mean like an enclosure? I need to buy one, not sure if I need to get a powered one with an A/C adapter or not. Some research I did indicates that the drive might need to be power cycled such that it is connected via power only (with no data) so that it undergoes some kind of power cycle. A usb-powered enclosure might not be able to do this.

No, I even reset the BIOS settings to factory default and it didn't work.
