As the only internal storage medium, I've recently installed a new and totally blank internal M.2 PCIe SSD in my Lenovo Ideapad. The Amazon link appears to give more information than Samsung's website, but it suffices to say that it's a Samsung PM981 512GB M.2 SSD.
As luck would have it, the BIOS recognises it just fine and, after changing from RAID mode to AHCI, it also shows up in both lsblk and sudo parted -l. However, my Xubuntu 19.10 Live USB's file manager shows no signs of knowing that it exists and neither does df -h.
It's quite well known that Linux often has trouble recognising M.2 PCIe SSDs, but in this case lsblk is telling me that the operating system knows that the SSD is connected. How could this happen? What do I need to do so that I can safely install Xubuntu to this SSD that Xubuntu isn't fully seeing?
