I currently use Ubuntu 20.04.3, but my M.2 SSD isn't being detected by Ubuntu.

My system: Ryzen 7 2700, Asus Ex-a320m gaming, ADATA SU650 120gb

I've disabled fast boot, secure boot, and SATA AHCI mode.

My SSD is new, I've encountered this problem before so I replaced the SSD with a new one and I still have the same problem.

    Many need UEFI update & SSD firmware update. What brand SSD? I downloaded Samsung update ISO for my NVMe SSD and created a bootable update. It looked like an old DOS screen and only had my model as an update. If you are dual booting with Windows you often can update easier. – oldfred Sep 22 '21 at 19:15

    Is the disk system set to AHCI mode, or RAID/RST mode, in the BIOS? – heynnema Sep 22 '21 at 20:05

    Use `sudo journalctl --since="-5 minutes"` within 4 minutes of inserting the SSD to see what's going on. – waltinator Sep 22 '21 at 20:16
  • The sentence *I've disabled* (...) *SATA AHCI mode* suggests you did the opposite of what you should have and that alone would explain the SSD not being recognized. You need to enable AHCI, the other modes aren't (yet) compatible. – ChanganAuto Sep 22 '21 at 21:39
