Today I disassembled my computer to clean it. Tons of dust. Felt great. Reassembled everything and…one of my HDDs isn’t showing up. Checked data and power, all good. So it’s a SATA port thing.

Looked at motherboard manual, looked at the charts/reference guides, thought I understood it, changed a port…the HDD in question is there but now my M.2 SSD isn’t showing up.

Also, I wasn’t expecting to need to be doing minor surgery on my PC so I took some edibles and they are hitting and I’m…I’m just lost. Everything I thought I knew is a lie. Help?

SPECS:

  • MSI x299 Raider motherboard (direct link to manual PDF, start at page 36?)
  • i9-7920x CPU
  • M.2 NVMe SSD in M2_1
  • M.2 SATA SSD in M2_2
  • SATA HDD connected at SATA2
  • SATA HDD connected at SATA4
  • SATA HDD connected at SATA3

This configuration results in M2_2 not appearing. If I move SATA3 to SATA6 one of the HDDs doesn’t appear.

I’ve been mucking with computers over 30 years now, I should have this but I’m so lost.

    SATA2, 3 and 4 are independent of the M.2 slots, so they should work. Make sure you’re actually using 2, 3 and 4, sometimes the numbering can be strange. On your board for instance SATA1 is on the lower right side of the SATA connector block.

     6 4 2
     5 3 1
    

    With a SATA SSD in M2_2 SATA ports 6, 7 and 8 should also work.

      Thank you for chiming in. Had to give up for the night due to lack of coordination but will be trying this tomorrow. Thanks again for your help!

      Hey again! Okay, this isn’t working. Not sure what’s up. In fact, the device in the second M.2 slot (SATA SSD) isn’t showing up either, now.

      Using 2, 4, and 6 only two of the three HDDs show up.

      USing 2, 6, and 7 only one of the HDDs shows up.

      In all scenarios the SATA SSD in M2_2 is just not showing up. Maybe it got loosened during the cleaning?
