Dual hard disc configuration HP EliteBook 840 G3 = > second SSD not recognized

[MontiPeiti]

Hi there, I have added a second SSD (Samsung 850 EVO SATA III 500GB/MZ-75E500E) in addition to the M2 SSD. However the second SSD in dual configuration does not show up, neither in BIOS nor in Windows. I have tried:

- Diskpart application: second drive not visible

- Diskmanager: same, second drive not visible

- Windows Explorer: no success either

- Legacy disabled, secure boot disabled: no success

- Legacy enabled, secure boot disabled: no success

- Legacy disable, secure boot enabled: no success

- I have also checked the SSD in another PC, there it works/it is visible

- removed and put back again, no success

Other relevant info maybe that I cannot find the HDD caddy, hence put in the second SSD directly without the caddy. But cannot imagine that this is causing the issue... right?

Thanks for any guidance.

Right. But the manual for the series says machine can ave M.2 SSD or 2.5" HDD/SSD, NO DUAL STORAGE option that may be the cause but beyond my imagination.

I will ask my friends to see more lights.

Thanks Banhien,

I should have mentioned it in original post that according to this document (in the drives section) it should be possible to have dual HDD configuration.
