SSD worked for a whle now it doesnot show up at all

Dell Latitude 5530 Intel I71255U, 32 GB Ram

Purchased a 2TB SSD and installed it on my laptop more than a year ago. I´m an update freak so I constatly make sure everything is uptodate windows, firmware and drivers.

At some point the computer would stop recognizing the 2nd SSD:

- Ussually it would happen after I left the laoptop on overnight, next day when i typed something the computer wuld light up normally but error message that onedrive could not be found (2nd ssd) what I would ussually do was turn off and turn on, this would normally fix the problem up

- sometimes, rebooting was not enough, then I would go into the bios, the drive was there, had to toggle someting on and off just to make a change and the rebooting would work perfectly

- NOW after a firmware update the ssd is simply not there, not in bios not in windows

Opened the laptop and everything looks good, no apparent reason for this

I havent learned yet how to uninstall a bios update but do you guys have any other suggestions?
