Dell G15 5511 SN850 disappears from system (when it's detected)

I recently got a Dell G15 5511 and have been trying to upgrade the drives in it. When installing in the 2nd (Gen3) slot, they are detectable but when in the 1st slot they are only detectable intermittently (usually from a cold boot) and quickly disappear.

I have tried multiple SN850s (1TB & 2TB) with the same result.

Has anyone experienced the same? Any suggestions?

Thanks

Hi @dev-null,

Thanks for reporting the issue.

Have you opened a Support Case? If not opened, for more information, please contact the WD Technical Support team for best assistance and troubleshooting:

Yes, I opened a case. They responded today and I am compiling the info requested. (As much as possible since it’s random if the drive is detected and for how long until it disappears from the system)
