Hi,
I have a similar problem than thread : Intel SSD not recognised by Intel Firmware updater, or Ubuntu Live USB, or CentOS boot USB
I used a SSD for several months as a boor drive and now it's not recognised as an UEFI boot drive and I can't see it in a live USB. But I don't have another system to test it.
Booting from a live USB does not recognise the SSD. This eventually gives the error: "nvme nvme0 identify controller failed (-4)". 'fdisk -l' does not show the SSD. The SSD is connected directly to the motherboard, was working before, and is:
Intel 600p 128GB 80mm PCIE 3.0 X4 M.2 SSD.
Motherboard is a SuperMicro A2SDi-4C-HLN4F.
Is there anything I can do to use it again? Any advice would be greatly appreciated.
