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?

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!
