[SOLVED] Manual says M2_2 slot supports SATA mode, though installed SSD isn't recognized

[whaduvah]

On motherboard ASUS TUF Gaming B450-PLUS II, manual says that the M2_2 slot supports both PCIe 2.0 x4 and SATA modes. I have installed a spare M2 SATA III SSD I had (model: WDS100T2B0B), which has B+M keys, into the M2_2 slot, but nor the BIOS or the operating system seem to recognize it.

The manual is available at https://dlcdnets.asus.com/pub/ASUS/...AMING_B450-PLUS_II_UM_print_updated091620.pdf, and the relevant section is "6. M.2 Slots (Key M)":

Is this a "copy-pasting" error from Asus or is there something I have to do in the BIOS for it to recognize my SSD?

What BIOS version are you currently on? As for your storage, can you list them for us as well as the slots/ports that they occupy?

BIOS version is 3802. There is a NVMe M2 1TB SSD (XPG GAMMIX S50 Lite, model: AGAMMIXS50L-1T-CS) in the M2_1 slot and nothing else.

Support web page spec sheet says, M2_2 supports NVME (PCIE) drives only). No mention of support for SATA drives.

Install SATA M.2 drive in slot M2_1 instead.

Aw, that's sad. Didn't want to do that because the NVMe SSD has speeds that the M2_2 slot can't handle, but I guess it's better than nothing. Thanks to you all.

Another option is using M.2 to SATA adapter and connecting to sata port on motherboard.
