Intel M.2 SSD 660p not detected in ubuntu

[vincent-tremblay]

Hi everyone,

I bought a new laptop, Acer Nitro 5 (AN515-54-58YY). I added a M.2 SSD PCIe of 512GB and can't make Ubuntu recognize/detect it.
BIOS detect it, Windows 10 and Windows 10 setup, detect it, but ubuntu live CD, installer, gparted, lsblk (or any other command), can't detect it. I tried Ubuntu 18.04, 19.04, 19.10 Daily build.
My windows FASTBOOT is disabled. Inside BIOS, I tried desabling FASTBOOT and SECUREBOOT options. Nothing work.
I can't change any option for AHCI or RAID option (I've done a lot of research on the web before asking here...)
Tried boot option nvme_load=YES, nvme_core.default+ps_max_latency_us=200 ...
BIOS is up to date, and firmware of SSD too.

The SSD is an Intel SSD 6 (660p) SSDPEKNW512G8XT.

Can it be incompatible with Ubuntu for any reason ?

Help me please !

Thanks !

Have you updated UEFI and SSD firmware? Even if new.
Almost all Acer will need "trust" setting in UEFI after install.

Acer Very latest UEFI/BIOS works, downgrade not required if no trust screens, you must now upgrade:

Acer Trust Settings - details, some now report that then secure boot has to be on to set trust:

Hi oldfred, and thanks for helping me !
Yes Bios(UEFI) and firmware of my SSD is up to date.

I can't configure my trust settings, because I can't even install my ubuntu, because I can't figure out how to make Ubuntu detect it (my SSD PCIe).

All post you share me is revelant only if I could install Ubuntu.

Thanks for your help !

I was hoping that firmware update was all that was required.
And sometimes those with same/similar system post additional info on issues, but I am not familiar with Acer other than lots of posts on "trust" issues.

You should have AHCI setting on drives somewhere. It may be currently RAID or Intel RST.
It may be under an advanced or IDE settings. (Which may seem backwards).

My Asus motherboard has UEFI settings all under the BIOS/CSM settings. Since CSM is an emulation mode in UEFI, it also seems backwards. CSM/BIOS settings should be under a UEFI tab or setting.

It is "RST Premium with Optane" in SATA Mode and I can not change it. It is in the "Information" page, and no other options on that in the others tabs ...
And under Boot Mode, I only got UEFI, no legacy, ahci, raid or nothing else ...

I really think I can't do anything !

Is windows 10 could make Uubntu installer not detecting SDD ?
I tried with GParted Live USB, and it do not detect my M2 SSD ...

Thanks

Microsoft requires vendor to let uses turn UEFI Secure Boot on and off. Probably for those with Windows 7 as it did not support UEFI Secure Boot.

Others have posted with Acer that you have to set a password in UEFI to open up additional settings. Do not lose password, or reset later to blank when done reconfiguring system.

In my unfortunate research, "Intel RST with optane" isn't supported in Linux. Since I can't disable it (nor change SATA mode) in BIOS, I'm stuck right there. Hope in the future, Linux will add support for it. Or Acer will add option to change it in a Bios update.
I will install win10 on m.2 and linux on slow hdd (disappointing). I will use F12 boot option to switch from one to the other at boot time ...

[oldfred]

I have yet to see a system that cannot be changed. Some UEFI setting somewhere will open up those changes.

Yes, but that doesn't mean the drive doesn't work in Linux. Phoronix tested Intel 660p m.2 NVMe SSDs using Ubuntu 18.04 about a year ago. Read here:

Yes, I know that the SSD work with Linux, but as I said, I can't change "RST" to AHCI ou whatever options for SATA in Bios. So I need Linux be able to handle Intel RST (because it can't detect SDD nor controller), or Acer to modify their Bios to let people change that option ... I'm really surprise to not find any solution to my problem. I searched solutions for more than 50 hours in the couple of past days with no luck. People will have this kind of problem more often and maybe someday will have solution, hack or evolution !
