My main computer currently has an NVMe hard drive, which is installed with dual operating systems, Windows 10 and Ubuntu 20.04. During use, I encountered insufficient storage capacity. Since the motherboard has multiple M.2 slots, I added a new hard drive, the WD SN770（1T）. However, it is strange that the new hard drive can be smoothly detected and partitioned in BIOS and Windows 10, but in Ubuntu, it cannot be detected using the ‘lsblk’ command or ‘fdisk -l’ and even the lspci cannot scan the device.
this is the lsblk result
