Hello everyone,

I recently upgraded my system by replacing the motherboard, RAM, and CPU. The setup is now:

• Motherboard: MB 860M-X

• RAM: Crucial CT32G48C40U5

• CPU: Ultra 225

I successfully reinstalled everything in my case, and the system boots up with all components connected.

The issue is that this motherboard only has 4 SATA ports. To connect additional drives, I installed a converter on the M.2 Gen5 slot: https://s.click.aliexpress.com/e/_DEJn6pL

When I go into the BIOS, only the SSD appears in the disk menu, since it’s the only drive directly connected to the motherboard’s SATA ports. The other 4 drives are connected through the adapter mentioned above. Surprisingly, Unraid detects all the drives correctly, and I can access my files on the server as usual (for example, from the local network and Plex).

My questions are:

• Is there a specific setting or procedure to make these drives visible in the BIOS?

• How can I check if transcoding is working (I didn’t have this feature before)? => followed an ibracorp video and i think it's working. can see hw in my plex monitor pannel.

• Do you have any tips to reduce system power consumption while idle? => I'am at around 45wats with, 1 ssd, 4 hdd and 1 stick of ram + cpu of course and plex only active. if i also activate the arr suite i'm at around 60w. => probably shoould make another post for that...

• Is it possible to automatically spin down the drives after a certain period of inactivity?

• Should I set the disks differently on my MB and adapter ?

Thanks everyone, and have a great day!

Add-on controllers typically don't show the devices in the BIOS; this is normal.
